Hanzawa Masato

Hanzawa is an easily amused, rather cryptic senior. Though he puts on a friendly exterior, he is not an easy person to read. He usually keeps his calm and rarely raises his voice. He is also very observant, noticing and remembering little details about the people around him. 

Between his various responsibilities such as his two clubs and his dorm headship in his second year, he still makes time to keep an open ear for his juniors and is there to help them out whenever he can. He is often seen teasing his juniors like Kagiura (for liking Hirano), Miyano (because he might not grow taller anymore) and Tashiro, though it is usually not with malicious intent. 

At school, he is described to have stellar grades and be involved in most extracurricular projects. He loves being kept busy and is sad to graduate.
