AU Premise: After stopping Demonseu and the Tobots' departure, the Galaxy Masters and their friends are dragged into the world of curses.

AU Bio: A general AU that serves as a continuation to the story of Taeyang and Pilseung and their friends. This takes place six years after Demonseu's defeat, and they are now in high school. There are age shifts, making Taeyang the second youngest of the whole group, while Pilseung is the oldest. At first, Taeyang is considered the leader, but after he turns, Pilseung ends up being the glue that held the group together.

Premise of the concept (inspired by Jujutsu Kaisen):

In Jujutsu Kaisen, all living beings emanate energy called Cursed Energy (呪力, Juryoku), which arises from negative emotions that naturally flow throughout the body. Normal people cannot control this flow in their bodies. As a result, they continually lose Cursed Energy, resulting in the birth of Curses (呪い, Noroi), a race of spiritual beings whose primary desire is to bring harm to humanity.

Jujutsu Sorcerers (呪術師, Jujutsushi, lit. "Cursed Technique Masters" or "Shamans") are people who control the flow of Cursed Energy in their bodies, allowing them to use it as they please and also to reduce its release. High-ranking Sorcerers and Curses can refine this energy and use it to perform Cursed Techniques (呪術式, Jujutsushiki), which tend to be unique to the user or their family. An advanced form of Cursed Technique is Domain Expansion (領域展開, Ryōiki Tenkai), through which the user can use their Cursed Energy to build a pocket dimension that covers the surrounding area within which all attacks will be stronger.

There will also be the addition of a concept called Bonds (채권, Chaegwon), where a group of people who share a strong bond can draw power from each other and empower the others. This is how the kids are able to access their cursed energy. Also, curses can be purified to become normal spirits with cursed energy still present.

Pairings:

Bak Gyeongpo x Lee Jihae, Pada x Pori, Kang Taeyang x Oh Pilseung, Rosie x Namhui (implied)

Characters:

1. Kang Taeyang (15) => Former Galaxy Master, becomes a Jujutsu Sorcerer specializing in the use of magical guns at first, but converted to a Curse User due to the bullying he endured from a young age and the trauma he suffered from things that happened while he was a Galaxy Master. However, after he was defeated by his friends, they welcomed him back and helped him get back onto his feet. He has a dark side whose eyes are red instead of brown and has powers of flight, speed and strength (see Eoduun Taeyang). Normally, though, his powers revolve around the use of guns, and he is the second-youngest after Jiuk.

2. Oh Pilseung (17) => Former Galaxy Master, becomes a Jujutsu Sorcerer specializing in martial arts. He has a crush on Taeyang, and becomes the unofficial leader of the group after Taeyang's conversion. His powers are within the range of fire, water, and wind, and he is the oldest member of the group.

3. Lee Jihae (16) => One of Taeyang's childhood friends who has a crush on Gyeongpo. Her Jujutsu specialty comes in the form of a bow and arrows which she can imbue with cursed energy to form nets that capture the curse. She is smart, kind, and cares for her friends, worried they would end up getting hurt in the process.

4. Lee Jiuk (15) => One of Taeyang's childhood friends, he is the youngest one, yet also the first one to access his cursed energy. He uses a spear that allows him to exorcise the demons if he stabs them right in the chest, except for special grade curses, which may require a bigger supply of cursed energy than usual. While he may be a bit of a coward, one can always count on Jiuk to be there for his friends, no matter how far they've gone.

5. Bak Gyeongpo (16) => One of Taeyang's childhood friends who is the third oldest of the group (behind Pilseung and Pori), he doesn't have a lot of cursed energy, but he's a skilled Jujutsu sorcerer with his mirrors, which he can use to trap spirits and to travel to different places that have a mirror marked by a bowl he made himself. He's a glutton, but he's brave, reckless, and trusts his friends very much.

6. Namhui (16) => One of Taeyang's childhood friends who used to be a bully as well, Namhui was changed by Rosie (King Majestic's daughter) and the others, becoming a mature yet light-hearted joker who lightens up the mood all the time. His cursed energy flow is irregular, due to his neglected upbringing and bursts of energy once in a while, but he uses this to his advantage by letting it flow through his butterfly net, allowing him to seal away curses and calm them down so they can talk.

7. Oh Pada (15) => Pilseung's younger brother who is the third youngest of the group, Pada is calm, cool, and collected, making him the voice of reason in the entire group. He fights with a dagger that allows him to cut through any Domain and curse, but at the cost of his physical energy. As a result, he's learned to rely on combat through skateboards, which doesn't use up as much energy but can kick someone far away. He tends to worry too much about his friends and family, though they usually find a way to calm him down.

8. Pori (16) => Pilseung and Pada's childhood friend who is the second oldest, Pori is excitable and physically gifted, which came at the expense of a lack of cursed energy. However, this does not dishearten her, but it became an opportunity to grow in wisdom. She is now fluent in all fighting styles, though she sticks with martial arts and seals to help her fight off curses.

9. Oh Hera (35) => Pilseung and Pada's mom, she is a dedicated policewoman who also ends up being a mentor in Jujutsu techniques, having grown up in a shrine. Her fighting style focuses on a random mix according to what she feels like using, granting her the element of surprise against her opponents. She's the mom of the group and has adopted all of them into the family, having distaste for Namhui's parents, who neglected their child and flaunted him around like a trophy instead of a human being. Kind, caring, and unable to let injustice go on, she hopes that they will become great Jujutsu sorcerers.

10. Jeon Iruk (16) => Pilseung's bully, he looks down on him and has a crush on Pori, though she has rejected him many times, calling him a hypocrite for hurting her friend and bringing down his self-esteem. He has tried numerous times to talk to her, only for her to shut him down. Arrogant, and willing to go to any length to win Pori's heart, he became a Curse User after being influenced by Eoduun Taeyang to join him. Luckily, he is stopped and sent to a juvenile detention center, but not after reconciling with the trio.

11. Swag (Unknown) => Taeyang's friend and former Galaxy Weapon, Swag is now a spirit who follows them around after Demonseu's attack and gives them help once in a while through a bond with Taeyang and Pilseung. He's a lover of rap and likes spending time with them and the others, who he considers friends.

12. Black Dog (Unknown) => Taeyang's former enemy, he is now a curse who attacks their school and exposes them to the Jujutsu world, only to be exorcised by Hera who arrived at the scene swiftly. Power-hungry and selfish, he would go to extreme lengths to get his revenge.

13. Star Ring (Unknown) => Taeyang's former enemy, he is now a spirit who tries to kill Taeyang as revenge for his defeat but was stopped by Ro-B, who had become a spirit bonded with Jiuk. After being exorcised, he decided to turn over a new leaf and bonded with Namhui. He's very sharp-tongued, but he slowly begins to change into a kinder person with Namhui's help.

14. Demonseu (Unknown) => Taeyang and Pilseung's former enemy, he attacks them while they are training so he could kill Star Ring, who he deems a failure. He is stopped by Taeyang and Pilseung awakening their bond with Swag and exorcised. He is power-hungry and would stop at nothing in order to absorb all of their cursed energy.

15. Octonaus (Unknown) => Pilseung's former enemy, he was controlled by Demonseu and is reborn as a spirit. He soon found a partner in Pori while she was figuring out her place in the group, and they found similar interests in fixing up the various weapons that tend to end up broken because of the others (*coughs* Taeyang *coughs* Namhui). He's the chill type, but mess with him once and he'll prank you until you apologize.

16. Utsukeratops (Unknown) => Pilseung's former enemy, he followed Octonaus loyally but died during the fight for Galaxy Weapon 6. As a result, he came back as a curse that attacks the group during an investigation in the Arctic. However, he was eventually defeated and became friends with Gyeongpo. He's loyal, gullible, and has quite the temper, but he's a good person deep down, even though he is a tsundere and refuses to acknowledge it.

17. Ro-B (Approximately 10) => Taeyang's friend, he is loyal to Star Ring but is determined to stop him, shown when he bonded with Jiuk and fought him off so he could be redeemed. He is a kind soul, innocent, and can be considered the baby of the group who is loved by everyone (something he and Jiuk can relate to, considering how much they don't like that.)

18. Eoduun Taeyang (16) => The other side of Taeyang, he is a powerful Curse User who emerges because of intense pressure. At first, no one notices and Taeyang keeps quiet about it, but it is only when the pressure gets too much for Taeyang that he fully takes control. Cruel, manipulative, and gifted with analysis, he is set on destroying all those who Taeyang holds dear in order to keep himself in control. However, it is soon discovered that this Taeyang was his dark side manifested due to his time in the Dark Matter Realm and in Demonseu during the final battle, and the darkness is exorcised by Pilseung with support from everyone else.

19. Robotstein (Unknown) => Pilseung's former enemy, he was destroyed in the battle to stop Demonseu from awakening and was brought back as a curse. However, with Bubble Cat's help, he is exorcised and brought back to life, allowing him to be with his loved one again. He's a bit crazy, but he truly does care for Octonaus, Utsukeratops, and Bubble Cat. He eventually bonds with Pada, sharing a feeling of exasperation towards their friends and comrades, and they can share their cursed energy too.

20. King Majestic (Unknown) => Rosie's father, the original owner of Galaxy Weapon 1, the Weapon Taeyang had been the Galaxy Master of. Becoming a curse after succumbing to the darkness of the Galaxy Weapons, he pulls the strings behind Eoduun Taeyang and is the final boss. He calls Taeyang unworthy of Galaxy Weapon 1, Swag a failure, and Pilseung a delusional boy with no dreams. After he is exorcised, it is revealed that he had fallen because of the power getting to his head, and he apologizes, calling all of them worthy of his daughter, especially Namhui, who blushes at the thought.

21. Bubble Cat (Unknown) => Pilseung's former enemy, they left to fix Robotstein's body, and came back upon feeling his signature there. They identify as genderfluid and tend to be bratty, but they are also caring, willing to go back to Earth to bring him back. They also end up bonding with Jihae due to their similarities.

22. Rosie (Unknown, Only Mentioned and Seen Briefly) => Member of the Galaxy Detectives, she is the princess of Unicorn and is good friends with all the members. While hostile upon her first meetings with Taeyang six years ago, she has grown close with them and had promised to come back one day. Even though this promise has yet to be realized, they wait for her, knowing she will fulfill it.

Plotline:

1. Six years after the fall of King Demonseu, Taeyang and Pilseung have grown closer with each other, and Pilseung, Pori, and Pada have joined the Galaxy Detectives. One day, during a sports event, they are attacked by Black Dog, and when normal means seem to have no effect, they try to distract him. However, he is soon exorcised by Hera, who realizes the kids can see the curse and promises to explain it at their home. When they get there, she explains curses and how it seems like the curse this time had a grudge against Taeyang. After a quick discussion, they tell her the story of the Galaxy Weapons, which doesn't surprise her at all. She then promises to teach them how to defend themselves, considering how they would be curses coming after them.

2. They've begun training at the cave where Galaxy Weapon 2 was found, only to be attacked by Star Ring. Jiuk, who is told to run, ends up bumping into Ro-B. Jiuk decides that he won't ever run away again, and rushes back to defeat Star Ring with Ro-B's help. After that, he is purified and Hera explains that when a curse is purified, they become a spirit.

3. Star Ring, now purified and regretful, stays away from Taeyang, knowing that he caused trauma for him. However, Namhui approaches him and they get to talking. With Namhui's help, Star Ring finds the courage to go up to Taeyang and apologise for his actions, which Taeyang accepts with grace, which allows Namhui to unlock his cursed energy.

4. Demonseu then attacks them, and while Jiuk and Namhui are able to hold them back, the others are helpless. Just then, Hera reveals Swag's presence, and while he is shy, he greets Taeyang. Demonseu is close to hurting Pada, but Pilseung pushes him out of the way, and Demonseu begins to take his cursed energy. Reminded of his purpose here, Swag quickly bonds with both and their cursed energy flows out, allowing them to exorcise Demonseu once and for all.

5. Pori begins to question her worth in the group and runs into Octonaus just as another curse attacks her. While unsure about him at first, they eventually work together and bond, allowing Pori to unlock her cursed energy. She then comes back with him, and the others welcome him.

6. During a visit to the Arctic, they are attacked by Utsukeratops. However, they end up defeating him and he's redeemed, allowing him to bond with Gyeongpo. Afterward, they head home, but Taeyang begins to get ominous dreams and headaches. When he is asked about it, though, he waves it off, saying he's okay. Once he's alone again, his eyes glow red, and he begins to speak in a deeper tone.

7. Their school is on a field trip in the mountain area, and there are stories of a spirit who attacks humans who wear cat ears and have blue hair. The kids decide to investigate, but they soon find Bubble Cat, who explains that they're here to find Robotstein. That's when they are attacked, yet it is only for a brief moment. Because of this, they decided to set up a trap. Using Jihae and Bubble Cat as bait, they lure him out, but his power nearly overwhelms them. Luckily, Jihae and Bubble Cat bond so they can beat Robotstein and purify him. After that, the two stay with them, but they also pass on a message from Rosie who promises to visit soon.

8. Pada and Robotstein begin to talk to each other about being used by others, and they grow closer over how ridiculous their friends are, which allows them to form a bond and unlock Pada's powers. However, on the other hand, Taeyang is getting more tired, and it is revealed to the kids through his diary when they check out his room that he is being bullied by upperclassmen at school, who rely on him to get them perfect scores for their assignments. They keep on threatening to hurt his friends should he ever make them fail, which puts pressure on him. When one of them comments how stupid he is & how he was better off dead, he snapped and Eoduun Taeyang appears, knocking them all down and dumping their bodies elsewhere before laughing and disappearing.

9. The news of not only the dead bodies but also of Taeyang's disappearance reaches his friends, and they are concerned. Swag says that he can't feel Taeyang's presence anywhere, which leads Pilseung to ask how that was possible. Hera explains that once one's cursed energy is unleashed, it cannot be closed again. Meanwhile, Jeon Iruk is approached by Taeyang with a new outfit, and he accepts the offer to join him. Eoduun Taeyang then grants him some powers, but promises to give him more once he kills off Pilseung and Pada. He then puts up a Domain where the kids are and tells Iruk to attack, which he complies to. Eoduun Taeyang shows himself once Iruk has them in one place, and they try to fight him off, but he can read their attacks and doesn't show hesitation to kill anyone, even lazily throwing some attacks at Pilseung without caring. They try to talk to him, begging for him to stop. Sadly, he doesn't listen to them and disappears with Iruk, but not before Star Ring notices a familiar silhouette behind Taeyang. Taeyang is soon seen putting up a Domain around the town, saying that with this in place, casualties are bound to occur.

10. The kids are devastated about the news and the fact that Eoduun Taeyang had put up a Domain around them so no one could get out, but Pilseung gathers them after some contemplating alone and tells them that they can't give up; trauma is meant to be overcome, and while it may never fade, he deserves to know that he is loved and accepted by his friends, no matter what. This empowers them, and they agree to go find him. Just then, he calls them, challenging them to fight him in the park. They accept and prepare to fight.

11. Arriving at the venue, they begin to fight Taeyang, but his strength is amazing. However, Pilseung notices similarities to Master V's attacks and deduces that Eoduun Taeyang's powers are inspired by the three Tobots from whom Master V came; Speed, Monster, and Rocket. With that in mind, he begins to combat it, and the others slowly make their way to Eoduun Taeyang. Then, Pilseung exerts a lot of energy into making a mini Domain for the two of them, where he gives Taeyang the comfort he needed for a long time. After Taeyang finds his resolve and breaks out of it, Pilseung collapses from the amount of physical energy required. Panicking, Pada uses his dagger to break the Domain, but faints as well, causing them and the super exhausted Taeyang to be taken to the hospital. Nearby, though, a silhouette is seen talking with the escaped Iruk.

12. In the hospital, Taeyang explains what had happened to him, apologising for never telling them. He is reprimanded by Hera, who is planning to build up a case against his school for allowing bullies like them AND Iruk to study there without strict discipline. The kids soon begin to chat, and Taeyang admits that he doesn't deserve to be the leader anymore, passing that title onto Pilseung, who is surprised but accepts it. A few days afterward, the three are discharged and most of them start searching for Iruk while Taeyang and Pilseung deal with the aftermath of Eoduun's rage. The bullies try to hurt Taeyang, but Pilseung kicks them back and gets mad at them for hurting his friend, calling them hypocrites who didn't know the difference between right or wrong. In the end, he beats them up and they run off, too scared to do anything else. Taeyang thanks him for this, and he blushes and waves it off. They soon get a phone call telling them that they had found Iruk.

13. Upon arriving at the scene, they start fighting him, but Star Ring notices the same silhouette from last time and exposes the person after they finally pin Iruk down; King Majestic, Rosie's dad. The kids are surprised, but he attacks them and even injures Iruk, calling him a waste of time. He then disappears, and Pilseung calls an ambulance while Pada and Pori do first-aid. Through this Iruk realises his faults and apologises to them. Hera shows up with the police and the medics, and Iruk is sent off to the juvenile detention center's hospital.

14. The kids regroup and allow Octonaus and Pori to fix their weapons, though Octonaus complains about how Taeyang and Namhui always seem to do weird stuff with their weapons, which makes them laugh. They then head off to the cave to train some more, only for them to fall into a Domain made by King Majestic, who attacks them brutally.

15. They fight with all their might individually at first, but then Pilseung realises they have to fight together, and they fight like a team just like how the Tobots had during the fight against Demonseu. After that, he is defeated, and the Domain is dispersed, purifying him in the process. King Majestic apologises for everything, revealing that he had been trapped in Demonseu for so long he had gotten delusional, but praises them for their wonderful collaboration, calling them all worthy before he asks Pilseung to exorcise him. Pilseung complies, and it is soon over.

16. A few months later, the kids are still combatting curses, but they're more relaxed and some have even begun dating. While Jiuk and Namhui have no one at the moment, Swag teases Namhui about his crush on Rosie, which makes him blush. The kids then promise to be there for one another, and to never keep secrets ever again. Hera calls them about a case in Jeju, calling them "special-grade sorcerers", which they agree to. After that, they soon head off.
