Has crab claws on their head, but these are actually a headband given to them by Momonga; they are not a crab. There are ears beneath the headband, tucked into the hollow space of the claws. The motif is unknown. The eyebrows are two short, slightly drooping lines. The eyes are perfectly round, modest, and kind. The body is a pale pink with a soft, rounded form. The top of the head is a darker pink, matching the headband. Despite the gentle and cute face, the teeth are jagged. The character is about 35cm tall with a two-head-tall proportion. They sell used books at the same spot every day, setting up a long vertical flag that says "Used Books" and opening a slightly worn-out parasol. They arrange several cardboard boxes filled with books and sit on a white box-like object in the center. Originally, they were one of the faceless background characters known as "Grey Ones" or "Mob-kawa." With the release of mascot plushies, "Used Bookseller" became the official name. Because the word "Crab" was written in the margin during the chapter where they were promoted from a background character, fans sometimes call them "Crab" or "Crab-chan." However, the claws are part of the headband from Momonga; they can be moved but have no cutting power. For narrative reasons, they are the type of Chiikawa species whose voice is "inaudible to the reader." They cannot speak words and express emotions through symbols like "!", "?", or "!?" and gestures. They run their stall in the plaza where labor recruitment takes place. They love reading and books, showing an active interest in anything book-related. They buy new books from the city bookstore using money earned from extermination labor, but they struggle with not being able to buy many at once due to low earnings. They are calm, kind, gentle, and shy. They are caring, devoted, and quiet. Instead of the representative ramen shop "Ro" in the Chiikawa world, they go to a shop called "Yama." They seem to be a regular there, with a specific order of "Firm noodles, rich broth, extra oil." When happy, they snap the claws on their headband open and shut. They like fizzy juice (especially apple flavor) and are often seen drinking it while selling books. Emotions and Gestures 【】 Surprised: "!!?" 【Waves hands up and down.
