Damien didn't know.
No matter what he learned, there was no way for him to understand his mother's strength.
After all, the records of the things she'd done back then had been erased from the world entirely. Even those who knew were forbidden to speak a word about it to others, lest their souls be taken by Samsara.
Claire made a sacrifice all the way back then. She sealed her power in return for silence, vowing to never bring it out again unless absolutely necessary.
And now that Dante was no longer able to calm her, it was unknown if anyone would be able to stop her if she truly let loose her power.
Nevertheless, because Damien didn't know, seeing his mother get injured was something he simply couldn't stand.
His body twitched.
He was absolutely prepared to do something stupider than anything he'd done in his life before by challenging the group of Gods around him.
After all, his mother's situation was getting worse.
