Кейта

Keita is the leader of the guild Moonlit Black Cats. Excluding Kirito, the guild was composed of members from a school's computer club.

On June 22, 2023, Keita went to purchase a home for the guild. After buying the house, he returned to the inn that the group had been using, and waited for his guild mates to return from the labyrinth on the 27th floor. Kirito returned alone, and had to tell Keita that everyone else died in the dungeon. Horrified, Keita committed suicide by falling off the edge of Aincrad.
