Things To Get VERY Clear On
1- Sparda and Eva are still alive in this and reside on Earth but to make this more interesting I'm gonna have Eva be like Salem and Ozpin by having her be a different breed of human.
2- Vergil and Dante will look like what they did in DMC 4 because honestly to my opinion that's when they looked their hottest but they will have their SIN Devil Trigger and everything else from DMC 5.
3- Their is no Nero in this one so sorry but I'm doing this since my other story has Jaune being Nero so doing it again or something similar would be a bit boring.
4- Love interests will be sprinkled out throughout the story as well as other crossovers so be on a lookout for that.
5- This story has inspiration from Demonic Heart and Jackpot! so if you wanna check those out the links will be in a comment.
6- To make this story a bit different there will be other mythology and folklore monsters to spice things up as I doubt a demon hunter would pass up a opportunity to kill a monster capable of matching demons in power. Also references to the game Minecraft as well since DMC having Minecraft stuff would be awesome.
7- Clothes and weapons will be varied but I will eventually have a same drip for him as well as weapon.

New Species- Enhanced Cambion- Half Immortal Human, Half Demon.

New Family

New Biological Father- Sparda

Alias- Legendary Dark Knight.

Code Name- Gareth Redgrave.

Species- Demon.

Relationship- Much like Ruby to her own mother, Jonathan idolizes his new father and sees him as his hero and his mentor since unlike his former father Sparda sees not only potential but like his tins sons a hero living inside of him so he spends his time training him in everything he knows and cares for Jonathan despite barely having met him. Reminds Jaune of Ozpin from his former world due to their somewhat similar personalities, their belief in his potential and their shared hair color.

New Biological Mother- Eva Redgrave.

Alias- Sparda's Mage.

Species- Immortal Human.

Relationship- For the first time in his life Jonathan was given a hug by a woman with a warm smile and warmth that made him feel loved. Adores Eva and has and will again pummel anyone that dares insult or worse harm her in any way. Eva is a reminder of Glynda Goodwitch who had helped teach him how to fight and often reprimands Team CRDL and Weiss for their bullying of him since Eva showed her warrior side by tearing out a monster's heart when it roared and made Jonathan cry. The other similarities are their use of telepathic abilities and their physical looks.

Adoptive Uncle/Resurrector- Hades.

Alias- King of Remnant's Underworld and God of the undead.

Code Name- Ciaran Darke.

Species- Old God- No there's not any other Olympian Gods.

Relationship- Known as the most powerful god in Remnant or at least when Remnant was first created, Hades had seen the worst and best of Remnant's inhabitants and of their clans but when his eyes landed upon Jaune Arc, he couldn't help but feel like he may have found something that could aid him in his control and domination of the Underworld. When Jaune "died" Hades reincarnated him onto Earth for a family that would train and care for him like he deserved with one day Jaune now known as Jonathan may become his champion.

Adoptive Aunt/Resurrector/Grandma Figure- Persephone

Alias- Queen of Remnant's Underworld and Goddess of the undead.

Code Name- Daeva Darke.

Species- Old God.

Relationship- Persephone has grandmother and aunt like vibes to her and adores Jaune's spirit as a child and loves it even more when he grew up on Earth though has a somewhat annoyance with the Underworld they were born from compared to the Underworld of Earth's due to the difference of the hierarchy. Now Jonathan having demonic blood within him she makes sure he's training those demonic abilities since demons from Remnant aren't strong enough to go to the living world after death like Earth's can nor do they have powerful or as powerful supernatural threats like Earth does.   

New Siblings

Older Brother- Dante Redgrave.

Alias- The Legendary Devil Hunter.

Species- Enhanced Cambion- Half Immortal Human, Half Demon.

Relationship- Jonathan loves Dante's carefree attitude and confidence which Eva says has rubbed off onto him as well as Dante's teachings of him in using firearms and other abilities their demonic heritage allows them to have. Dante reminds Jonathan of Ruby and Yang due to his powerful weapons and his carefreeness. The two share a close bond of both being the youngest siblings or in Dante's case formerly and is the one that gave Jonathan the nickname Johnny.

Eldest Brother- Vergil Redgrave.

Alias- Dark Slayer.

Species- Enhanced Cambion- Half Immortal Human, Half Demon.

Relationship- Bit rocky at first since someone appearing from another dimension like Earth is a bit suspicious but Vergil did quickly warm up to his new younger baby brother after seeing his motivation for the first time and loving it. He teaches Jonathan about having a code of honor while also mastering the power you have and the ones you should only gain with your own hands and with your own willpower. They both have a close relation and a very strong trust for each other to the point that Vergil has lent Yamato to Jonathan before on his missions. 

Other allies in his missions.

First One- Trish Burgio (Her DMC 4 voice actress's last name)

Alias- Fiendish Femme Fatale and The Bewitching Devil.

Species- Demon.

Relationship- Trish upon first meeting Jonathan two weeks after he turned 18 had him for a moment mistaken her for Eva so he hugged her as she herself believing it was Dante she jokingly hugged back only for them to see each other and be surprised. Since then Trish teases Jonathan about love and girls but also does teach him how to be flirty since from experience knows how much manipulation is a good weapon against others. Occasionally Jonathan will do one against Trish that will get her to smile and during their missions will wrap her arms around his neck, nuzzle her face into his chest or neck and even leave kisses on his cheek.

Second One- Lady Arkham but last name is abandoned.

Alias- Armed Hunter For Hire, The Walking Arsenal and the heavily armed beauty.

Species- Peak Human.

Relationship- Having very troubled family lives, the two actually hit it off right away and loves the other's company so they work together a lot and Lady loves how Jonathan is much much smarter in using his expenses and actually getting paid as compared to his older brother as well as impressed of how humans seemingly "evolved" from his former home world. Much like Trish Lady often teases him with girls and how he has better luck than Dante and Vergil in getting a lady to actually speak to him and does snuggle with him to cement that.

Third One- Nicoletta "Nico" Goldstein.

Alias- Artisan Of Arms.

Species- Human.

Relationship- Despite her constant cursing and wild child attitude, Jonathan loves her energy and views Nico as not only his first friend on Earth but also someone that will always have his back through thick and thin so he is protective of her and of what she makes for him though does find ways to make it up to her when they end up breaking.

Final One- Xiomara Viper.

Alias- X, The Viper and Fangs.

Species- Cambion- Half Demon, Half Titanoboa Faunus.

Semblance- Medusa's Successor.

Relationship- Having met Jonathan when he was merely four year old Jaune Arc, they admittedly hit it off as friends when instead of being scared or disgusted by her Faunus features, he was intrigued and thought they made her look cool and pretty in his own words. After finding out Jaune was getting bullied she started beating on Team CRDl and was ready to attack Weiss when something was ready to hit Jaune and being the loyal and courageous friend she was, she ran to him to try and help when they both "died" and were reincarnated but while Jaune was reincarnated as the third and youngest child of Sparda's bloodline, it is unaware of what or more who Xiomara was reincarnated as due to her lack of physical similarities to Sparda but with her lifelong friend and her secret crush by her side, they are both determined to find out who.   

(Her eyes in her Devil Trigger form)

Jonathan's New Looks-  Now has silvery white hair and bright blue eyes or actually bright blue eye on the right side while the left side is a silvery green color though they both have special features to them that make them unique. His training has given him a raging eight pack abs of muscle and is like his brothers a very handsome person with many girls falling head over heels for him. He stands at six foot four inches tall a inch shorter than his brothers and always has a necklace around his neck that his mother gifted him. (Ignore the piercings, jewelry, fingernails and rings)

3- Aura And Demonic Energy Mixture- Can mix demon energy and Aura together and infuse them into a weapon or object to strengthen it and turn it deadly.

This greatly increases his strength, speed, durability with whenever he is hit or harmed the kinetic energy increases the strength and density of his muscles and bones to further increase his durability and strength and his regeneration at whatever level of power and speed it is to increase tenfold.
