Shiroyama is a shut in who spends most of his life in the confines of his room, and boasts an incredibly low attendance record at Hope’s Peak. Despite this his calibre in mathematics is matched by few, writing papers and advancing knowledge on all fronts forwards. He generally hates the outdoors and is not seen very often by his peers or his family. Shiroyama comes off as a cold person at first, but it is clear this is due to a lack of social experience as he rarely talks with others.
