Beni

Beni takes the form of a sparrow. He has red feathers and wears a beaded necklace and getas, complimenting his owner's traditional Japanese fashion sense and association with the color red. It is unknown if he has a different form when entering Rhyme like Ren and Usagimodoki.

Beni, while technically the tiniest out of all the Allmates, has a large temper to make up for it. He has a no-nonsense policy and is shown to be quick to react to tough situations, similar to Koujaku. Despite that, Beni can be very relaxed and shows to care about other's well-beings. Girls particularly find him cute and will call him as such when they're around Koujaku (unlike his owner, however, he simply takes the compliments instead of gloating about it).
