They have no face, however, their skin complexion is white, they have a small but fine mouth. Is seen wearing a military uniform and possibly white gloves.
Ichi is a very serious and careful person with their work. They seem to have a strange relationship with Nana, who calls them "mangy".
- Ichi/壱 means the number "one".
- Their face/mask is probably based on the famously known "Slender Man" considering they are both tall, slender, pale, and have no face.
- Their voice actor also voices Keisuke Naoto.
- Since Ichi is "one", we can guess they're the first admin to appear, so maybe they got their stick from "The King" herself.
- They are a former Magical Girl, like the rest of the admins. But when Nana spoke with them, Nana used he/his pronouns.
