Ryoji will be in Group B for this plot. That basically means he remembers the brainwashing, yet is grateful for it because he can properly do his job now. He'll be completely under control and won't feel any need to fight it, and he'll stick to patrolling the dormitory floors and ordering whoever is in Group B or C. If anyone's acting out of line, he'll kill them.

The modifications specific to Ryoji are as follows:
-a scythe embedded in his skull, which he may occasionally pull out to kill people
-scorched skin that is dripping with something acidic
-access to all supernatural powers (this may include Nyx Avatar and immortality, but I'm checking on that)
-Most importantly: he can sense death among the residents of the Tower and will kill people associated with it. When he malfunctions, everyone will seem to be fated to die, and so he'll kill them as slowly and painfully as possible to bring about that.

Basically, if your character is in any way connected to death, let me know here, or on Ryoji's permissions post. In most cases, this will apply to characters that have died, murdered someone, or seen someone die (canonically more than Tower-wise, though both can apply), and in extreme cases this may even happen with people who are already injured. Of course, once he completely malfunctions, everyone seems to have death hanging around them, so if none of this applies to your character, they can still tag him!

Here's a reference of his changes, and other that that, I'll be putting up an open log. Comment here if you want to plan out anything beforehand!
