Hajime nods. "It's definitely been a long time." A long, awkward time, made all the more awkward by the fact that Hajime remembers another version of Kenzaki on some other world and is dealing with some kind of lingering reincarnation memory thing, and that Kenzaki's dealing with some kind of fake alternate universe memories...

If Hajime's looking a little green, well, that's what happens when you have green blood and you're feeling intensely awkward with this whole scenario.
