Kou is quite possibly the most annoying character from any of the seasons ever. He's completely insufferable, especially in his first few episodes, where he does nothing but skateboard, cry, feel Lin's breasts and look up girls skirts. Even for a kid, I don't know why his behavior was tolerated, especially by Lin, who should have kicked him in the crotch several times. At no point does he seem worthy of the powers or responsibility.. The only reason he doesn't completely ruin the show is because he's barely in it. He doesn't even bother to show up for the finale, which should have been disappointing, but..
