A rather serious student who is also into astronomy, Matagu seems to be the most hopeless of the cast, a classic "nerd". He is much less confident and self-assured than Hyousuke, or even Kei, leading one to conclude that he suffers from crippling shyness. His stated fondest dream is to meet with "an alien creature from outer space", totally unaware of the fact that his teacher certainly qualifies as such, and that he has had several conversations with his life's dream in a very normal setting. He even considered to confess his love to her, but his shyness put a halt to his plans.
