[is that minding your own business,

in any case. Kuro is a busy demon! Zeno waits a few days before getting paranoid, and it takes him a few more to figure out what's happening, where his demon is.

then... he rampages. it's not a quiet process, getting himself hurt and killed enough to make a real weapon of himself, and then it's very not quiet when he starts killing in return. by no means is he gentle or merciful.

but it's fine! it's fine. all this means he can rip the cell door right off, stride in covered in blood and scales and cold, brutal violence.]
