Takateru Akiyanagi is a member of the school's literary club who always writes poems.
Takateru is often refered by his friends as "Taka," Japanese for Hawk. He is easily inspired to write haikus from everyday events and carries an old style Japanese ink brush and parchment with him.
According to Taka, he has a younger sister who had been hospitalized for a while and he'd cheer her up by making silly poetry. Eventually she got better however but that is the extent of what we know.
Also, Taka enjoys teasing Saki even though that usually results in him getting smacked upside the head.
