I think I've said this before on other pictures of Yus getting crucified but if Saint Peter didn't deserve to die in the same manner as Jesus Christ then I don't see why a living confectionery that can't count to ten does.
Well, Peter now needs to hear "Give us sweet sweets shitty old men, we angel-yus now." x 1000 times a day before he drops them to hell, then I think a bit of pre-death reward by not being crucified wouldn't be wrong. Then again I don't hold them to posses souls.
Also imagine St. Peter's book of sins. Reimu did bad things and must go to hell, and thousands of reimus then claiming they're not reimu or it must be that reimu over there and further in the back claiming they are reimu.
