Remember to play the fandisc. The after stories may be subpar at best, but it's worth it for the Houzuki story.
But that doesn't really make sense. When Touka was wearing Ririko's clothes, Ririko was wearing Touka's uniform (at least, the CG says so). And since Touka's uniform hides the tattoo on Ririko's shoulder, no one is able to know that Ririko is actually bearing the Maximum Penalty.
Anyway, edited the first post so it makes sense and looks prettier. Because I like pretty things.
