Iura Shu (井浦 秀 Iura Shu) is a friend of Izumi Miyamura, and everyone, he attends the same high school. He is enrolled in class 3-2.
He has green hair and brown eyes. He often wears a sweatshirt and his purple headphones.
Iura is loud and outgoing. He's best friends with Ishikawa. He likes to play pranks on people, and tends to be the one starting the games or activities done by the group. Everyone in the group finds Iura to be annoying. He's like the human form of a green ball of energy.
Seemingly destined to never have a girlfriend, Iura spends a lot of his time bemoaning this fact. However, Iura doesn't have his sights set on any particular girl, so nothing usually comes of this. It is mentioned that if Iura would just be quiet sometimes, there would probably be a lot more girls interested in him. But as Iura says, "if you take away my energeticness, what would be left..."
At home, he is completely different, acting very subdued and even cold towards his younger sister, Motoko. However, despite this cold attitude, he still loves his sister very much, and tries to help in in whatever way he can.
Iura's ex-girlfriend. They dated for a little bit during their freshman year, but eventually broke up. In Iura's words, "She was loud and couldn't read the mood. It was like looking into a mirror. I hated it..." Despite this, they still remain friends to this day. Nanako has yet to make an appearance in the comic, except for a few flashback pictures.
When Kitahara came over to the Iura house to visit Motoko, his first impression of Iura seemingly awakened something inside of him, and Kitahara became drawn towards Iura. They share a common interest in music, particularly rock, and Iura acts like a older brother towards him. However, no matter what feelings, if any, Kitahara has for him, Iura definitely does not reciprocate.
Shuu's younger sister. Shuu frequently acts cold towards her, and played lots of pranks on her when they were younger, however deep down, he cares her. He often tries to do subtle things or things behind the scenes to help support her. His nickname for her is "Moto".
