Keqing Took My Honkai Voice Pack Seriously

An Zhen transmigrates to the continent of Teyvat, where Keqing takes him in. He also gets a voice-line System, giving him the best possible start: he draws the Honkai voice pack, and as long as he activates it, he can keep getting stronger. But he never expected Keqing to hear his chuunibyou voice lines.

[Humanity, your very existence is a mistake. War, deceit, jealousy, greed. You took everything from me, but today, I will devour it all. Because I am Honkai!]

Keqing: ???

[Weak, insignificant, and presumptuous. Your desperate struggle will only hasten your death. After all this time, you still don't understand that.]

Keqing: ???

[Humanity, make them submit!]

Keqing: ???

[The time has come for judgment!]

Keqing: So you're the great demon king who wants to destroy the world?

P.S. The Honkai arc is now in full serialization!
