Younger Sister: Motoko Iura
Host of: "Let's try asking Iura-kun!"
Shuu's basically the energetic guy everyone knows from high school—he's friends with Izumi Miyamura and the rest of the crew. He's got his own take on things and genuinely gets excited about stuff, which makes him outgoing and yeah, sometimes annoying. That's kind of his thing. Around his younger sister Motoko though, he's way more laid-back and reserved, though it's clear he cares about her. Music is a big part of his life; he's always passing CDs around to friends, trying to get them into whatever he's listening to.
