Everyone at school knew the two names, Sukuna and Yuji. No matter who you ask, students, teachers, or the janitor, they always have a story to tell about the twins.

Sukuna was quiet, and stoic yet feared by most if not all, of the school. He had a handful of "friends" he seems to label as people he tolerates. Despite having a terrifying reputation he was the more academically smart twin, so it surprised people when it was revealed that he was actually the younger twin, considering how much more mature he was compared to his older counterpart.

Yuji, was loud, bubbly, and loved by all, if you weren't on his bad side. He was the more popular twin, and surprisingly strong, as he gives off a sweet aura to everyone he meets. He wasn't the brightest in Maths and English and often had to stay behind to finish his work, but he believes it's fine as long as he passes (he doesn't).

It was Thursday after school at 4 pm when the twins left the building. Yuji's karate club had been canceled so he watched Sukuna's gymnastics practice instead. As they walked out, Yuji was being a usual chatterbox.

"Sensei said I could get a black belt if I keep on working hard!" Yuji proudly told Sukuna about his potential to be a champion of the karate club.

"Okay?" Sukuna replied, that he didn't see how it was a massive achievement.

"Aren't you happy for me, Kuna?" Yuji frowned at his unenthusiastic reply.

"Maybe I'll be happy when you get the damn thing." Sukuna rolled his eyes, there's no point in getting excited, he hadn't seen a black belt yet.
