kuronosu (chronos in english) has the ability to go through flow state manually, as long as the body can handle. he has a very overpowered ability to see results in an event (foreshadowing future), like he can predict the future, (not yet canon but) he fights alongside his brother (trying to think of a name yet) against his arch nemesis (no name yet as well LOL), as he predicts the future with his ability, there is victory, but only he remains, this means that no matter what, no matter universe, no matter result, his brother's fate is decided, and is meant to die.
this causes him to lead in a very severe depression, throughout the lore, throughout the fights, he tries to be better, the more he understands, the more he accepts, and the more he becomes better than who he was
