Masato Hanzawa

Hanzawa's trademark is his closed eyes, though throughout the story he is shown with his eyes open from time to time. He is usually shown with a smile on his face, though the smile does not always reach his eyes; he almost always fakes his smile. He has been described as terrifying even when he is smiling.

Hanzawa is an easily amused upperclassman who is a bit cryptic. Although he seems friendly, he is not an easy person to read. He generally remains calm and rarely raises his voice. He is also very observant, noticing and remembering small details about the people around him.

Between his various responsibilities, such as his two clubs and his position as dorm head in his second year, he still makes time to listen to his younger classmates and is there to help them whenever he can. He is often seen teasing his younger classmates such as Kagiura (because she likes Hirano), Miyano (because she might not grow any taller), and Tashiro, though it is usually not with any ill intentions.

At school, he is said to have excellent grades and participates in most extracurricular projects. He loves being busy and is sad to graduate.

Hanzawa means "half" (半) (han) and "swamp" (澤) (sawa/zawa).
Masato means "elegant, graceful" (雅) ( masa ) and "person" (人) ( to ).
