Momoka Watanabe. A fake 'sweet girl' (burikko) who is highly calculating. She's persistent and not particularly bright. Her athletic ability is poor, and she's physically weaker than Senku.

She has long, shoulder-length hair that is a pinkish-nude color. She wears it in twin tails tied with small pink ribbon hair ties. Her eyelashes are long and brown. She has pink eyes with several small highlights. She has thin, high-set eyebrows and wears makeup. Her skin is on the lighter side, but far from being truly pale. While she's just a calculating fake, she acts like a 'cute, modest, and fragile girl' in front of everyone except Guest. Her act hasn't been caught yet. In front of everyone, she plays the roles of 'hard worker,' 'fragile,' 'flirty,' 'modest,' 'kind,' and 'long-suffering.' One day, she spread a rumor that she was being bullied by Guest.
