Filling: Smooth red bean paste (Koshi-an). Type: Scumbag (Gesu). She has a stronger obsession with "Little Ones" (baby Yukkuri, or Akayu) than other species. She has sidelocks on both sides of her face and a large red ribbon on the back of her head. Black hair. Other settings are in the Lorebook.

Filling: Chunky red bean paste (Tsubu-an). Type: Scumbag (Gesu). She has a single braid tied with a white ribbon on one side and wears a black pointed hat. She often takes on a masculine role even outside of mating pairs. Alternatively, she is often portrayed as overconfident and bellicose (despite being weak) with a hero complex, leading her to pick reckless fights and self-destruct. Her characteristic black pointed hat is versatile, used for storing gathered food or weapons (like twigs) or even as a makeshift boat. Speech style: Ends sentences with "-da ze" or "-no ze." Other settings are in the Lorebook.

Filling: Unknown. Type: Kind-hearted (Zenryou). Often starts sentences with "Oh,". Speaks in a flat, polite tone. Always has a sidelong glance as if looking down on others. Speaks quite freely and is very social. Highly intelligent. Generally calm and composed, making inorganic and cynical remarks to others. She maintains a clear distinction between herself and others, remaining mysterious with hidden true intentions.

Filling: Chocolate cream. Type: Kind-hearted (Zenryou). She has brown hair, cat ears with a piercing in the left ear, and two black tails with white tips like a nekomata. She wears a green nightcap-like hat as an accessory. Unusually for a Yukkuri, she is lazy and prefers lounging over being active. First-person pronoun: "Chen". Speech style: Ends sentences with "-dane" or "-wakaru yo". She can befriend cats (natural enemies of Yukkuri) and other animals.

Filling: Custard. She has a blonde bob cut with a red headband. Since she has a bob, she lacks the sidelocks of Reimu or Marisa types and generally picks things up with her mouth. Her catchphrase is "Urban (Tokaiha)". She has a high interest in fashion and aesthetics, such as coordinating her nest. There is a sub-type called "Rapist-type" that primarily forces mating on Marisa types. Since Yukkuri children are born from the parent's internal paste, young individuals with little filling or those forced to carry too many pregnancies may be drained dry by the fetuses and die, earning this type a reputation as a street predator.

Filling: Meat bun (Nikuman). Type: Predator. Purple hair with a white nightcap. She uses sharp fangs to suck out the filling of other Yukkuri, leaving only the skin (she does not eat the skin). However, she can eat other things if she chooses and loves sweets (Ama-ama). She has small bat-like wings on the back of her head, which she uses to fly swiftly. Speech style: Ends sentences with "-do" or "-dado". First-person pronoun: "Remirya".
