I don't know why, but I think Yoite's SOB SOB AAAANGST is pretty deserved, though most people seem to think it's way over-the-top.
He's slowly and agonizingly dying while his senses are disappearing one by one, he has no idea of who he is as a person (lol intersexed
, named after a cat), it's apparent that most of his family hated him (for killing his mom or something?), someone shanked him in the neck, he's discovering that living (with Miharu and Yukimi and etc.) isn't so bad even though he was so determined to erase his own existence, and he's just a sixteen-year-old. A lot of teenagers are way more emo than Yoite, and they lead rather normal lives.
