[Change of Pace]

Spoiler:

I'm actually betting Bones WILL keep Shinigami dead, just to add impact and change and be different. Maybe throw in an epilogue several years in the future with Kid over seeing Shibusen with the Thompson sisters as his death scythes? And older!Mifune and Ann teaching, and the whole lot? Idk, I don't think there's reason enough to revive Shinigami; Bones may have Maka-tachi defeat the Kishin in the end (which, imho, is sort of bull shit because, asides from the fact that I find Maka an extremely irritating character, they really are NOT strong enough, no matter how you slice it.)

In any case, like I said, I'm betting they'll keep him dead because there haven't been many deaths in the anime rendition, and, y'know, I think Bones could pass Shinigami off as the necessary "sacrifice" !
