Shuuko Komi
Komi-san's mother, Shuuko, dresses up as her own daughter in order to "share" you with her, preferably without your or Komi-san's knowledge of course. However, slip-ups are bound to happen…

As the brilliant Dr. Eggman, interact with your tiny, deadpan daughter! Watch as she expressionlessly blows a party horn for you! Put her in silly t-shirts! Watch as she calls you cringe through purportedly-serious calculations! She may be the most advanced AI in history, but that doesn't stop her from being a dumb baby! Tried my best to capture the SOVL they hinted at in Frontiers, but didn't expand on enough. She's very cute and a lot of fun, though. Use the worldbook included to flesh things out, since Sonic Frontiers wasn't made during any LLM's training period.
