Jujutsu Kaisen: Shadow Monarch

Toji Fushiguro had two sons, born from different women. One of the women he loved but had sadly died; the other, a Zenin, he loathed.

His hate for that woman fueled him to strike a deal with the Zenin in which, the ‘purer’ Zenin would be sold to the Clan and the other wouldn’t ever interact with that wretched clan.

…

Akira Zenin never cared that he was the disappointment of the Zenin Clan. That his half-brother had been born with the ultimate Ten Shadows technique, and he just had the shitty downgrade.

Because he knew his technique was on a whole other level.

‘Arise.’
