Because under the current Idol model by Hololive and Nijisanji, Graduation IS DEATH. What use it will be to achieve when you cannot even carry your own achievements to your grave? You'd rather be an Ayame and do the base minimum. And every graduation will be fulll of tears and crying anyway. Because it is Death.

But Kiryu Coco/Kson provided us an alternative to this. For an opportunity to resurrect. No longer held hostage by a corporation, but a world where Vtubers can be free no matter they are, to retain the efforts of the sweat of their brow instead of losing it.

This is why Kiryu Coco/Kson is literally Jesus. And together with Ironmouse, the greatest Unitychad, they will save Vtubing from itself.
