Shoubu wa Toki no... Un Daro? Seven

Shoubu wa Toki no... Un Daro? is actually a series which Takaguchi co-writes with another artist. SEVEN is a solo work using many of the same characters, but takes place slightly later. It is about the members of the basketball team at a sports-based high school.
The first chapter focuses on a new character, Kiyoshi. Although he is attending a sports-based school, he is unable to play sports because of a childhood accident. He isn't dealing well, until Nana (Seven) takes him under his wing and asks him to be the manager of the club.
Nana is a senior and captain of the basketball team. Kiyoshi quickly falls for him. But most of Nana's attention is focused on his coach, Saegusa. The man practically built the basketball team from scratch and was manager at one point. He played basketball in middle school, but fell prey to some kind of chronic illness and wasn't able to play after that. All his life he worked with the goal that he would one day be able to play again. But suddenly, he realizes that it will never happen. He begins drinking and becomes depressed. Nana works to pull him out of it, and perhaps they grow too close...
