Tadokoro's given name finally makes sense.
But, y'know, I'm wondering now... Tadokoro was bullied so much in middle school, how come nothing bad ever happened to the bullies? A parent notices these things. I would have expected a development like this:
1) Kirigaya & friends bully Tadokoro.
2) Kirigaya returns home.
3) Kirigaya sits in front of TV, switches it on.
4) That's the last of Kirigaya, as nobody ever hears of her again.
That sounds perfectly reasonable.
But it would have cramped Nikaidou's game, as it would have left her without any opportunity to display her gallantry by rescuing her paramour in distress from the clutches of dastardly enemies.
So, reasonable had to be discarded here in favor of cool.
