Towa is such an interesting character; he doesn't have a will to do anything, but he still does. He still goes to work and goes out even if he doesn't want to. All of his love interests suck for their own reasons, Rei less than the rest.

You know there's a "secret" route in slow damage; you have to play through Fraise, Rei, Taku and Madarame for it, though. It starts with Towa waking up while a vampire movie is playing in the background. He then goes into a monologue about vampires. Then over the week, there are sudden attacks of on random people who wake up with vampire bite marks and a stack of cash.
