Kasane Teto (重音テト) is an UTAU character; UTAU is a freeware vocal synthesizer designed for singing. Teto was originally created as a joke of sorts on a forum, but she ended up becoming very popular, even officially recognized by Crypton, and appears in things like the Project DIVA games. Due to her popularity, she is essentially the face of the UTAU program. She is owned by TwinDrill.
These are cute bare feet with pink nails that match the Teto nails in my catalogue! They have a super cool, reddish-pink gradient, and they're very shiny. Now you can have realistic bare feet with awesome nail polish to match your fingernails!
