Kuchi

口

A minor character in Layer 06 who speaks with Lain Iwakura while she searches for information on KIDS. He can be viewed as a stereotypical netizen who associates with famous figures in the Wired (such as Lain) to boost his own reputation among other users. Lain finds him irritating.
He appears as a toothy, grinning mouth due to his inability to fully metaphorize, noting that Lain is remarkably powerful for being able to manifest herself completely in the Wired. The Cat adds that most people can only manage ears. Lain labels him a wannabe Cheshire Cat (チェシャ猫気取り).
In Visual Experiments Lain, he is referred to as Kuchi (口, "mouth").
