Kerori

Kerori (ケロリ, Kerori) is an MMO player who joins the guild that Mahiro is briefly a part of.

Personality
Kerori is shown to be a troublemaker. He had only just joined the guild that Mahiro was a part of, but Mahiro claimed not to like him. He was supposedly able to tell that Mahiro was really a guy based on how she typed, but Mahiro said that she was just being polite. He demanded proof, and was subsequently very shocked when Mahiro got on the voice chat to prove him wrong.

He is also shown to be a bit of an online predator as he apologized to Mahiro while also asking her to send him pictures in a private message, though Mahiro was self aware and knew to never send pictures to some random guy.

His actions ultimately lead to infighting within the guild over Mahiro and its subsequent disillusion.
