Y/n changed into his sweatpants as the rest of team T/n got ready to sleep, while the others were doing their own thing Y/n prepared his gi for the training he had in midnight.

Ken: "I still don't understand how you can't throw a Hadoken yet Takeda"

Takeda: "I'm still trying to teleport consistently Ken, don't think I'm going to get to that part soon"

Ken: "Even Y/n juggled both Grandmaster Hanzo's and Gōken Sensei's teachings"

Y/n's head wasn't in the right place at the moment, he was paranoid for what's to come of Gōki's training. It wasn't hidden from the telepath of their team however.

Takeda (Mind): "You okay Y/n? You are on edge"

Y/n sighed as he looked at Takeda from his shoulder and told his lie.

Y/n: "It's about the mission I partook with team CLICS, now we have four groups of criminals we have to worry about"

Ryu: "We are not ready for all of them at once yet, our leader shouldn't worry so much about problems bigger than himself"

Ken wrapped an arm around his neck.

Ken: "It's going to be alright bud, I'm very sure that everything will start settling down once we are out there taking names and kicking ass. Until then just relax, we won't be students in Beacon forever"

Y/n put on a fake smile on as he pats Ken in the shoulder.

Y/n: "Alright man"

Ken: "Atta boy!"

Takeda: "Now let's get some sleep"

They all went to their beds and after some time fell asleep...except for Y/n of course, he quietly got up and put on his gi, Ansatsuken gloves, and secured a rope dart on his belt.

Y/n ran through the Emerald Forest going from tree to tree in the moonlit night, he felt the presence of the Dark Hado inside a cave. Y/n took a deep breath and exhaled as he entered the mouth of the cave, it was dead silence except for the dripping of water inside the cave. He then looked up to see Gōki sitting on a large boulder, the glow of red in his eyes already made Y/n intimidated. Nevertheless Y/n bowed to his third master.

Y/n: "Sensei"

Gōki leapt off of the and landed in front of Y/n.

Akuma: "I will teach you how to manifest and control your dark hado, it will be of aid once you truly tap into the Satsui No Hado"

Y/n: "What exactly is the Satsui No Hado?"

Akuma: "The Satsui No Hado is a force based on the dark side of Hado and rooted by the evil of a human's instinct, it can be something as necessary as survival to something selfish as victory. It can grant immense power to the user but with a price. If not controlled it can easily overtake the user turning them mad and stripping away their humanity"

Y/n: "How can you control such power?"

Akuma: "Training and mental conditioning, but seeing you have gone through hell when you were younger and trained with my brother and one of the greatest ninjas of Remnant you gaining better control of such dark power would be easier"

Y/n remembered every torment that has happened in his childhood and how he then hardened into one of Master Hasashi's greatest ninjas and Gōken sensei's students, Gōki could sense his thoughts but to his surprise he couldn't sense a strong feeling of hatred within Y/n's soul.

Akuma: "You don't have any form of hatred towards your tormentors, after everything they've done to you?"

Y/n: "I was able to move on, and during the training with the Shirai Ryu helped me understand that dwindling in the past will make me miss the chance of a better future"

Akuma: "Hmph, you ignore the pain instead of using it to your advantage and fuel your soul"

Y/n: "I don't ignore it, I will always remember the pain I felt. I just refuse to let it cloud my mind"

Akuma: "Let us see"

Gōki charged up as an aura of Dark Hado surrounded his body, Y/n went to a combat stance ready to fight.

Gōki leapt up with a fist ready to collide against his new student, Y/n blocked it with his arm and blocked another incoming punch from Gōki which open him from a downwards back fist to the back of his head.

Gōki then went for a round kick and a spinning hook kick combination but Y/n kept on blocking staying on the defense against Gōki's offense, he then broke through his defense with the demon flip and landed many hits on Y/n with a spinning hurricane kick.

Akuma: "Tatsumaki Sempukyaku!"

Y/n landed on the floor and balled in ki in his hands and blasted it as Gōki.

Y/n: "Hadoken!"

Gōki parried the incoming attack and charged in with a heavy punch to Y/n's gut and continued it with a medium and heavy uppercut causing Y/n to fly upwards.

Akuma: "Gō Shoryu!"

Y/n eventually had enough, his eyes lit ablaze and teleported. He teleported in front of Gōki throwing an overhead punch and a fiery spinning hook kick to his face, out of blind rage he unravels the rope dart, coiled it around his elbow, and shot the flexible blade weapon at Gōki.

Y/n: "Come here!"

An aura of dark Hado surrounded Akuma and phased through the attack and behind Y/n, the young ninja then turned and did a scissor leg sweep on Gōki. Y/n went on mount and pulled the rope hard shooting the kunai into his hand, he raised it over his head ready to stab Gōki.

Akuma: "Well done"

Y/n's eyes extinguished as he allowed Gōki to get up, he coiled his rope dart and put it away.

Akuma: "I will teach you how to manifest dark hado"

Gōki did a kata similar to the one Gōken Sensei taught him, strong stances and open hands. Gōki went to a low stance and shifted his hands channeling hado into his hands, he then curled them forming a purple hado ball in his hand. Gōki then disbursed the hado.

(Only GIF I can find that shows this kata)

Akuma: "Eventually you will be able to use dark hado without the need of this kata, now you try it"

Y/n nodded, he took a deep breath as he got into the low stance like Gōki's and shifted his hands. He then curled his hands and create a ball of hado energy, it flickered between blue and purple as Y/n tried to control the darkness within instead of letting it form. The hado was disbursed and faded away.

Akuma: "You repel the darkness, why is that"

Y/n: "I refuse to allow myself to be the very thing that hurts the ones I care for"

Akuma: "Let go of your worries, let your mind be cleared of such cowardice and let the darkness in your ki flow"

Y/n nodded as he meditates for a short moment, he focused on the darkest part of his mind as he then went into the low stance. He repeated the process until a purple ball of dark hado energy, Y/n never felt this power before and it was becoming unstable. Y/n yelled out as his palms started to burn as the hado ball grew more and more dense.

Akuma: "Release it now boy!"

Y/n: "Metsu! Hadoken!"

Y/n blasted the dark Hadoken at the wall of the cave causing a loud and large explosion, luckily for them they were far away enough from the academy where no normal human can hear them. The Hadoken that Y/n produced took a toll on his body as he started coughing uncontrollably and even spat some blood out, he panted as he went through the pain.

Akuma: "Hmph, you were able to learn one of the Satsui No Hado's gifts faster than I did"

Y/n: "W-What just happened?"

Akuma: "You took the toll of your first experience of Dark Hado, because your body is not conditioned for it's power you were weakened by it. Further training with condition your body to handle the dark hado"

The master helped his student up after he recovered, Y/n was still drained after using Dark Hado and Gōki knew that.

Akuma: "We will continue this again, you will come back the same time"

Y/n: "Hai"

Akuma: "Now go, before someone finds you in here"

Y/n nodded as he traversed back to Beacon with new knowledge for himself, knowledge that will lead him to a new future.
