@mr_joe_343 Nice idea, man. I was also thinking the same thing. If Kaito's gonna be with Mei all the way, maybe he'll say a cool line like "If I can be with you, Mei, then that's enough reason for me." And then Kaito will say this next:
"To prove it, I'll say this right here, right now: "By the gleaming light and the iron in my soul, I, Kaito Hasakawa, pledge myself to you, Raiden Mei. My sword shall be an extension of your will, my stigmata a bulwark against your foes. I will stand by your side in many of battles to come. My fealty is sworn not by earthly decree, but by the threads of fate that bind us. Let my courage be your strength, my loyalty your comfort. I shall be your chosen, in life and in death, until the world's end itself"
Something like that. Sorry if u think it's exaggerated, but I just want to say that I fully support Kaito joining with Mei. After all, even in the original DMC games, Vergil and Dante are walking their separate paths.
