Keita
Keita (ケイタ, Keita?) was one of the 10,000 players who were trapped in «Sword Art Online» and the leader of the «Moonlit Black Cats», a small guild, before committing suicide after finding out that most of his guild got wiped out, as well as Kirito being a beater.
Appearance
Keita had short brown hair and brown eyes and was dressed in light, brown clothing with a metal chestguard, metal shoulder armour on both his shoulders, metal bracers on both of his arms.[3] He also wore black, fingerless gloves that extended to his forearm and dark boots.[3] Keita's trousers are of a paler shade of brown than his top.[3] Keita's weapon of choice was a two-handed staff.[4]
Personality
Keita was a person who put the welfare of his guild above everything else and was described as a hopeful and forward type person, whose dreams were to be on the frontlines of SAO, helping to clear the game.[4] However, after finding out about the deaths of his guildmates and that Kirito was the only one who survived due to his level, Keita gave into despair, cursing Kirito, and committed suicide by jumping off the edge of Aincrad.
Chronology
Aincrad Arc
Red-nosed Reindeer
Keita was in the guild Moonlit Black Cats 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 dissuade the group from opening the chest, which, upon being opened, triggers a trap that leads to the death of all the members present in the party, except Kirito.
Keita was devastated when he was told the news of his guild members' deaths and he commits suicide by jumping off the edge of Aincrad, leaving Kirito as the last surviving member of the group.
