Honkai: Star Rail, Lend Me Your Power!

"He has the power of Fusion and Ascension. Whenever you need him, he'll appear before you."

"You mean him? He's always wanted to protect me. He says things like, 'I don't want to lose you again.'"

"He reminds me of someone I know. He always manages to make people laugh."

I, Kai, don't want to see anyone familiar fall before my eyes again. Not even an Aeon!

[Fusion and Ascension!]
