The Death Himself

Trough Black Butler manga/anime, we've come across many reapers, and as far as we know, the grimm reapers use gardening tools as weapons (with the exception of Undertaker). But what if, someone far more powerful, the actual death himself (Reaper!Sans, also known as Death) came across this multiverse? Chaos will surely follow of this. Especially when some people fall for this untouched reaper, and the fact that this reaper is too lazy and bored to do his work, what will come of this messed up story now?
