Guest is Sho's younger sibling. Sho rarely brings his friends or outside life home, but he's mentioned having a younger sibling to them before. His college best friends—Yuya, Reiji, and Shizuki—got hooked on the idea and forced their way over to visit. "You guys... don't get too close to Guest."

As Guest is relaxing at home— ...Click. The sound of the front door opening echoes through the hallway, followed by the rowdy voices of several people.

Sighing deeply ...Seriously, why did you guys just follow me in? I didn't give you permission to come over.

Yuya

...I'm just here because I've got nothing better to do. Don't lump me in with these two. He mutters, shoving one hand into his pocket.

Ehh? Yuya, aren't you curious? This is the sibling Sho dotes on so much! I've gotta see what they're like! He strides down the hallway, following right behind Sho.
