Masato Fukuroi (袋井 雅人 Fukuroi Masato ) is a student from Byakudan Senior High School class 2-4, a victim trapped in Heavenly Host Elementary School, and a minor character introduced in Corpse Party (PC).
Masato is a teenage male with average height and weight. He has short, semi-spiky tan brown hair with a widow's peak, and brown eyes. He wears the Byakudan Senior High School male uniform, consisting of a white shirt, a blue striped necktie, a Byzantium purple blazer, black pants, and brown shoes. He also wears round eyeglasses.
Masato is a classmate of Yuuya Kizami and the student council president of Byakudan Senior High School. He has a stiff and serious personality, but is also surprisingly caring. He complains when Ryosuke Katayama and Tomohiro Ohkawa loaf around the student council room, but then forgives them. He used to be bullied back in first grade, but Kensuke Kurosaki came to his help when he was depressed and he overcame it.
Although he trusts and favors fellow student council member Mitsuki Yamamoto, he will not show it openly. Mitsuki’s strict and severe coaching of the student council president is her own way of showing consideration.
Masato's corpse can be found in the second chapter in the main hall on the first floor, next to Kai Shimada and Tomohiro's remains. According to his name tag, he was struck with a weapon and then stabbed with another, bleeding out.
Masato is seen along with Mitsuki during the Chapter 3 opening. After seeing the corpse of their classmate, Emi Urabe, with a large hole in her head, they run through the halls. He tries his hardest to calm Mitsuki down, who's starting to panic, and they come across a hall that seems to have opened up. While trying to understand why this new path is suddenly there, Mitsuki notices something down the hall behind them. Yoshikazu Yanagihori then charges them, and strikes Masato with a sledgehammer.
Corpse Party: Book of Shadows
Episode #5; 『Shangri-La』
Masato appears during the events of Chapter 5 alongside Mitsuki and assists her in searching for their classmates. During the chapter they encounter Sakutaro Morishige and ask for his assistance in finding their friends. Eventually they find their friend Emi, however she seemed to be at breaking point and runs away as Mitsuki and Masato leave Sakutaro behind and chase after Emi.
If you choose to load a save made just before interacting with Shougo Taguchi's body as Sakutaro and having already finished the chapter once, you will relive his last moments (which are very similar, if not exactly the same albeit expanded, to the ones in the canon timeline), in which he tries to defend Mitsuki from Yoshikazu, only to end up being grievously wounded and left for dead. He is later found by Yuuya (who he doesn't recognize, as he is unable to see him clearly), begging him to help the others. However, Yuuya simply ends up killing him, going after Mitsuki shortly afterwards.
- Masato's birthday is on Christmas.
- Masato shares his first name with another character.
- Masato, Takamine Yanagihori, and Mikio Tsubota share the same voice actor in Corpse Party.
