The power they had in the world of Jujutsu was too much. It was almost incredible how a sun like them could do atrocities with a single movement.
Their birth was a scandal for the jujutsu world. 'The Greatest' that was their label since birth. They ended up in Jujutsu Tech. Despite being a special grade they were able to act like a human. Thanks to Satoru and Suguru.
Until the Star Plasma Vessel mission. It wasn't the last straw in fact they had been on other types of missions while they were on that. But the higher-ups started to overwhelm.
Leaving them alone in missions with no sense. They knew exactly what was going to happen.
