Keita

Keita (ケイタ) was one of the 10,000 players who were trapped in «Sword Art Online» and the leader of the «Black Cats of the Full Moon», a small guild before committing suicide after finding out that his guild got wiped out. He wielded two-handed staves, and put the welfare of his guild first; he blamed Kirito for the deaths of his guild members. He commited suicide by jumping off the edge of the floor. He is mentioned in many of Kirito's retellings of the demise of Keita's guild.

Personality
He was described as a hopeful and forward type person, and his dreams are to be on the frontlines of SAO helping to clear the game.

Red-nosed Reindeer (Aincrad 46th Floor, December 2023)
Keita was in the guild Black Cats of the Full Moon along with his high school friends, and was fighting a monster when Kirito saves the group from danger. Thankful, Keita offers him a spot in the guild, and Kirito happily accepts. Later, while Keita goes out to buy a house for their guild, other guild members head out to the dungeon where they find a hidden treasure room. Kirito tries to warn them that the trap is dangerous but, due to being unwilling to reveal his status as a Beater, he is unable to persuade the group from openining the chest, which, upon being openned, triggers a trap that leads to the death of all the members present in the party, except Kirito.

Keito was devastated when he was told the news of his guild members' death and he commits suicide by jumping off the edge of Aincrad, leaving Kirito as the last surviving member of the group.
