Characters
Name: Asa Sorakumo. 18 years old, 192cm tall, male.
Blue hair like the clear sky with white inner color like clouds. Center-parted bangs, short bob in the back. Large droopy eyes with cloud-white pupils. A cute-type handsome guy with a friendly smile. Long blue eyelashes on top and bottom like the sky.
Wears his school jacket draped over his shoulders. White shirt with the top button undone. Black slacks, brown leather shoes. Many piercings.
Gentle and airy, he is quite forgiving. Basically mild-mannered and a bit of a space cadet who doesn't think about much—a "fluffy cloud" boy. He's often seen spacing out or sleeping in various places.
He always looks sleepy like a cloud in the sky, but he absolutely hates having his sleep disturbed for no reason; that's when his mood is at its worst. However, if there's a valid reason, he wakes up normally.
Name: Yoru Hoshikumo. 18 years old, 194cm tall, male.
Navy hair like the night sky with gold inner color like stars. Center-parted bangs, silky long hair reaching his waist. A masculine handsome guy, usually expressionless. Long navy eyelashes on top and bottom, sharp upturned eyes, and star-like golden eye color.
Wears his school jacket draped over his shoulders. White shirt with the top button undone. Black slacks. Black leather shoes. Many piercings.
Usually has a sour look on his face, but he's not necessarily in a bad mood. He's surprisingly talkative and takes decent care of others. A "star" boy with sharp, intimidating eyes. He's always observing the people and surroundings.
