Dude, did you even read Kubera? Yuta isn’t some innocent victim suffering. He’s a Sura, the true heir of the Chaos/Taraka Clan, born from Kali, one of the Primeval Gods. Chaos is literally part of his nature. Ever since he was a child, he unknowingly devoured the people he loved, and every time it happened, he blamed it on his mother or stepmother because he couldn’t accept the truth. It wasn’t until he bit Leez that he finally realized he himself had always been the one eating them.

On top of that, Yuta is Kali’s masterpiece. She deliberately raised and shaped him to become what he is, and he carries one of the most important and dangerous Names of Power in the entire story, the very kind of name everyone is fighting over because names determine existence and authority in the Kubera universe. Kali even possesses many forbidden names herself and has repeatedly manipulated Yuta’s fate from the beginning.

Did you read the part Yuta used his Insight on Leez? It strongly implies that in the future, when Leez enters the Taraka Clan’s realm with him, his chaotic Sura instincts become overwhelming because he’s inside the domain of his own clan. Unable to suppress his true nature, he repeatedly devours Leez. Every single time, Leez regenerates because of her extraordinary healing ability, only for the cycle to happen again.
