You know I just have a crazy idea and it about Locke Crimson, A AU story here life another day and end up in Gensokyo. His power happen to be Blood-controlled, All the gappy sue gag and them Ren (Zero) came to see him and ask him, who is he really and how could he replaces His Human-like. This freak Locke out and doesn't understand what Ren is talking about.
And the dark truth that he is Ren's humanity. Taken from him in the reboot and life on as another being away from the Zero.
I wand to know if I should make Locke Crimson as the Former Part of Zero?
