Wow! Looks like Demon Boy: Red Rose of Revenge is not available on any streaming services in the world!

Genre

Something's different. Something's wrong. He says there were events he doesn't remember, there are things in his room he doesn't recognize... and in the end, he has no choice but to quit his job without even realizing it... he's had a constant sense of discomfort, as if he's being watched or framed by someone.
