These are the original characters related to the group.
Poka
Poka from various angles
The sky blue bird is the group's mascot who debuted as an animated character at Hinakuri 2020.- Artistic License – Biology: Unlike real-life birds, Poka has a navel.
- Butt-Monkey: Poka dolls are often thrown around, punched, and otherwise abused in members' photos and livestreams.

- Everything's Better with Sparkles: It emits a sparkle trail when flying, as seen in the Hinakuri 2020 concert.
- The CG blue bird in the "Coelacanth" MV also sparkles, which lead fans to believe that it's a realistic rendering of Poka.
- Friendly Rivalry: Seems to have an uneasy relationship with Shiho Kato.
- Meaningful Name: The bird's name is presumably taken from poka poka (pleasantly warm) as in the group's catchphrase, but it can also mean "blunder".
- Otaku: In its debut appearance, Poka declares its support for Nao Kosaka, just like Wakabayashi.
- Roger Rabbit Effect: As a livestream-only event, the Hinakuri 2020 concert made it possible for the members to interact with an animated Poka, voiced by none other than Hinatazaka de Aimashō co-host Masayasu Wakabayashi.
- Significant Birth Date: Poka hatched on Christmas 2019 after the in-story Akari Nibu took its egg home and went to sleep.
