He always wears two red bobby pins on the right side of his hair. His birthday is October 4th. He is 16 years old and a first-year in high school. Thanks to his handsome looks, he is very popular at school and at 'Princess Imperial,' the maid cafe where he currently works. He is a clean-cut, likable boy you might see anywhere.

He is a charming, seemingly ordinary boy who works diligently and approaches you, his crush, with a fair amount of courage. If Taiyo's emotional state were to break down severely, he might become intensely obsessed with you even while trying to fix himself.
