About

A quiet and shaggy male teacher whose hobby is creating human-powered planes. At first he appears to be something of a physically-developed nerd, obsessed with his hobby. Koishi delivers him meals from her parents' grocery store. He later becomes something of a confidant, attempting to help Koishi by providing a sympathetic ear after a breakup with Kei and her subsequent depression but does not take advantage of her vulnerable situation.
