Tetsuo

Tetsuo (テツオ) was one of the 10,000 players who were trapped in «Sword Art Online» and a member of the «Moonlit Black Cats», a small guild. He was killed along with most of his guild except for Kirito when a trap was triggered that called multiple monsters and prevented the use of crystals.

Tetsuo was a mace user and the only front line attacker in his guild's formation. Besides his mace, he also used a small kite shield in his left hand. He wore a set of black armor, consisting of a chest and shoulder plates. Underneath the armour, he wore a purple tunic.

When Kirito was invited into their guild, Tetsuo expressed joy with his guild mates. He was one of the people that supported the idea of hunting in a dangerous dungeon and dies on June 22, 2023 in a trap in the Labyrinth of the 27th Floor, along with the other members of the guild, except for Kirito, who somehow survived, and Keita, who was not there.

Trivia

 * Other than Kirito, Sachi and Keita, who were already named in the Light Novel, Tetsuo was the only one in the Moonlit Black Cats to have his name mentioned in the anime, outside of the ending credits.
