Matsumoto

Matsumoto, nicknamed Matsun, was Iruma's best friend and fellow player on the baseball team. They were known as the Freshmen Duo.

Personality
Matsun was a cheerful, joking guy who always sacrificed himself for Iruma's sake. He also had a crush on Kumano.

History
On the day of the Dolly apocalypse, he and Iruma managed to win a baseball game for their team. He sacrificed himself and used his bunt to bring Iruma home. They later went to a pool in order to celebrate with their team, and Kumano. However, Wasps suddenly appeared and he pushes Iruma and Kumano into the water and jumps in alongside them in order to avoid being stung. While the rest of his teammates died due to the Wasps, he finds out that the Wasps are weak to water. The three make a break for it and hide in the school, but a Dolly crashes a plane into the school. The debris from the crash cuts off one of his feet, but he manages to hobble away with Iruma's help.

However, the Wild Dolly appears and tries to suck all three of them in. Matsun, seeing that there is no other option, sacrifices himself in order to save Kumano and Iruma by letting himself get sucked in--along with a large piece of debris from the crash, in order to buy Iruma and Kumano enough time to run. He dies when he is finally sucked into the Dolly's vacuum. He was 15 at the time of death.
