Five years later

Y/n walked out of the school after he finished classes. Nero was waiting for him already in front of the building. Y/n was walking slowly, Nero could easily say something was off. Y/n made his way to his father with a frown on his face.

-Hey Champ. – said Nero ruffling Y/n's hair. – What's up?

-Nothing. – muttered Y/n and started walking right away.

-I can tell something isn't right. – persisted Nero as Y/n sighed.

-My classmates are laughing at me cause I have white hair. – said Y/n looking down.

-Did you tell the teacher about it?

-Yeah, but they didn't really do much. – answered Y/n with a shrug. – Can I dye my hair or something?

-I don't think it would solve anything. – answered Nero. – But don't worry about those assholes. I have white hair too, my father and uncle did too. Don't forget you're a great grandson of the Legendary Dark Knight Sparda. They are just jealous, you'll kick their butts when you'll grow up. – Nero scratched the side of Y/n's hair. – You should be proud of your roots.

Y/n kept coming home angry after the day in school all the time. Seeing this, Nero figured out it was a right time to teach Y/n how to fight. He bought a punching bag and the boxing gloves. Kyrie protested at first, after all it was damaging Y/n's innocence, but it was better than damaging his personality with constant bullying. Nero hung the bag in the garage, and picked Y/n up from school.

-I don't want to go there anymore. – said Y/n when they were sitting in the van.

-I already thought about it, but running from the problems won't really solve them. – answered Nero and parked the van in the garage.

-What's that? – asked Y/n when he saw the punching bag.

-The solution. – said Nero. – Eat the dinner, after that we will start training.

Y/n nodded his head and made his way in the house. The plate with food was already waiting for him. As he ate, Kyrie picked the clothes for Y/n to use for the training. Y/n finished his food fast, got changed and went back to the garage. Nero was waiting for Y/n already with the gloves in his hands. He put them on Y/n's hands and showed his how to punch properly. With that little tutorial being over, Y/n started beating the hell out of the bag.

-I can't anymore. – Y/n panted out after half an hour of torturing the punching bag. – Those gloves are heavy.

-Because they are boxing gloves, they have to be heavier to protect your fists. – answered Nero.

-But it feels good. – smirked Y/n. – I feel so light now.

Time skip

Y/n was using the punching bag every day after school. Nero added some weight to it and showed him how to block the punches from the opponent. Y/n added it to his training routine. Nero watched him from time to time, happy that Y/n smiled more after releasing the stress after his boxing session.

Few weeks later Nero was called to school. He got there, he was supposed to pick Y/n up anyway. He walked in the building, ready for the serious talk with the teacher. He opened the door to the classroom loudly and crossed his arms against his chest. Y/n was sitting at his desk. Nero ruffled his hair, then turned his attention to the teacher.

-I wanted to talk about your son's behavior. – she said. – He beat up three boys today.

-At once? – Nero asked Y/n, who grinned.

-Yeah.

-Were they your bullies? – Nero continued the questioning.

-Yes. – nodded Y/n crossing his arms against his chest, just like Nero.

-So my son is getting detention for protecting himself from the constant bullying about his looks. – said Nero, leaning against the desk beside Y/n. – Y/n was reporting it to you and the other teachers and no one did anything about it. Now you dare to punish him for fighting back? For protecting himself when you didn't even try? I'm taking him out for ice cream now, cause he did a damn good job. Next time I hear a word from Y/n that someone is making fun of him, I'm going to make sure we end up in courtroom. – after the tirade he turned his attention to Y/n. – Let's go Champ, you deserve a reward.
