Masumi is a member of the Spring Troupe and the second actor to join the Mankai Company. He falls in love with Izumi at first sight while watching her act in a street performance. Masumi himself has no motivation for acting on his own, and his only reason to join was to get close to the Director and to be praised by her. His interactions with everyone else are mostly rude, so he is deemed as a troublemaker. Despite that, his sense and line memorization ability really stands out.
Masumi comes across as cold and indifferent with no motivation whatsoever. Furthermore, he could be described as rude or even brazen, as he has a sharp tongue and is not afraid to use it against strangers or his fellow actors. To blame for this attitude is his rather carefree, unrestricted life, due to his absent parents as well as the lack of discipline. His behavior changes a lot once he interacts with Izumi, the woman he claims to love. With her around, he turns into a lovesick puppy. He flirts and tries every way to gain her attention. Masumi's impolite remarks turn into compliments and he, in some way, seeks her nonstop approval, something his parents could not give him. Even with constant rejections from Izumi, Masumi remains persistent.
His parents work overseas, leaving him to live alone in Japan. Having no reason to return to an empty home, Masumi spends his time wandering around doing whatever he feels like. One time during his walk through the city, he witnessed a street performance by Izumi and Sakuya with the goal to gather more members for the Mankai Company. Watching Izumi's acting caused him to instantly fall in love with her, and he decided to get close to his new crush by being the next addition to the acting troupe.
