Katsumi Matsunaga

Katsumi Matsunaga is a Yomiyama North Middle School student from the 3-3 class of 1983 along with Reiko Mikami and Akiyama Ryoko. During 1983, he managed to successfully stop the calamity in class 3-3 ; the only recorded case of the phenomenon stopping halfway through the year.

History
In 1983, Mr. Koga, the homeroom teachers of class 3-3, organised a trip for 2 days and 3 nights at Yomiyama Shrine. Then restoring the Abandon Yomiyama Shrine to its original shrine and praying to remove the curse. After praying at the shrine, Mr. Koga declared everything would be okay and the class is free of the curse. After leaving, the sky turns overcast, and it begins to rain, everyone leaves the shrine and Matsunaga is walking behind Hamaguchi and witnesses his death. After this, he has a fight with a classmate in the forest. They begin to argue so badly that Matsunaga gives him a punch and accidentally knocks him down, piercing his head on a tree branch, killing him. Katsumi, terrified, runs away until he is questioned by the police who arrive at the scene. The next day, he returns but the body has disappeared. When he asked his classmates about the classmate (his name can't be heard because the tape was



altered by the calamity), no one remembers him. Katsumi realized that he killed the extra one. Afraid he would forget his findings, he recorded his theories and confession on a tape for the following years' students to find' and hides it in classroom. But in time, even Katsumi forgets what happen in the class trip. After graduation, he moved to Tokyo to pursue his studies. He became a banker but dropped out after a few years, and returned to Yomiyama to help with the family business. He actually works and lives in a hotel.

Plot
He made his debut in "Sphere Joint" in Tomoka's flashback.

In "Hair Stand", after he learns that Reiko looked for him at the beach hotel, he went out to look for them. On the shore, Matsunaga had a chat with Reiko and the others; he and Reiko both comment how long it's been since they've seen each other, and Katsumi tells his old friend she hasn't changed much since Middle School. However, the fun at the beach is cut tragically short by Junta Nakao's death, despite the group's efforts to save him. Shocked out of his post traumatic stress disorder, Katsumi remembered the tape's location.

At the beginning of "Glass Eye" Kouichi, Naoya, Yuuya, and Mei listened to the repaired tape, and learned how to end the Calamity: Send the Dead back to Death. Yuuya later shared the tape with Izumi and Takako, which unfortunately caused more problems than it solved and led to most of 1998's curse related deaths.

Appearance
He has brown hair, brown eyes and a negligent appearance. He is seen wearing an outfit which consists of a pale blue T-shirt, a dark blue shirt, a pair of pale pants and dark blue shoes.

While he is never shown in the manga, in the live action film he appears briefly when Kouichi and Mei interview him about his year's Calamity. He wears the uniform of a hotel valet, and most notably, he's missing the fingers from one his hands, a wound he self inflicted for killing a classmate.

Personality
Katsumi seemed an ironic and superficial person. When he comes out about the 9th Grade Class 3 curse he turns out to be agitated and stressed.
