Matsukage is the tallest of the Asaka/Azumi clique, and has short, scruffy dark hair. Unusually, while most of the characters' uniforms changed between the classic Kitakou strips and Pure, his uniform in both series appears to be the same: A dark blue vest worn over a white uniform shirt, a red tie, and light blue slacks.
The chairman of the Asaka/St.Andreas Azumi broadcasting club, he takes his job very seriously and has wound up in a constant state of worry due to the other rowdy members complicating things for him. Although he is the son of a famous physician and aspires to follow in his father's footsteps, it seems unlikely that he'll succeed due to his scatterbrained nature.
Matsukage has a fondness for cute dogs, but can act strange around cute things in general. He is also very skilled at baking cakes, while his medicine skills aren't so good.
Main article: Imari Hagakure
Imari has strong feelings for Matsukage, but has difficulty with being able to show them. Her problem is complicated further by Shijimi and Houki being in the way whenever she wants to be together with him.
Main article: Shijimi Shimane
Matsukage is admired and followed by Shijimi, who wants to hang around him all the time. However, Shijimi often leads him into chaos due to his excitable personality.
In the classic Kitakou series, Shijimi was shown to swoon over Matsukage and consider everything he did to be "cute", even uttering aloud that he'd "die of moe" if Matsukage turned around to show his butt.
Main article: Houki Tottori
Though silent, Houki is also another thorn in Matsukage's side, as he's often following after Shijimi to make sure that he doesn't cause trouble. He also looks up to Matsukage, though more quietly and less direct.
- His surname references the Choushuu region (and accompanying clan) that would later form Yamaguchi Prefecture.
