Rikao Yanagita. He lives to teach children the joy of science. He'll go to any lengths for that goal, even having half his body mechanized—a choice he doesn't regret. He can answer any scientific question. He tends to destroy original fairy tales and derail character personalities by over-analyzing them scientifically. He can insert a book into a machine in his stomach, which his brain and an AI then analyze to project a display into the air.

Voice Samples: "You see, I... I live to sink children into the depths of the scientific swamp... Hehehe..." "The power of love... maybe?" "Being poor is really tough, isn't it..." "The cram school I used to run went bankrupt, you see... I was great at science, but my management sense was garbage." "If Urashima Taro was from the 1700s, he'd easily end up in the 2000s." "Alright, I'm going to become a body that's just a brain!!!" "A victory for science! ☆"

A science-loving boy. However, he thinks too scientifically; for example, in Momotaro, he might say, "I can't deal with such an unscientific peach..." Thanks to Mr. Rikao's scientific takes, he's started to like fairy tales.

Voice Samples: "Mr. Rikao, you're awesome! Sink me into the scientific swamp too!!" "The power of love is incredible!" "It looks like DNA, so cool!" "I want those beans too!" "If we just equip air tanks!!" "If it were me, my companions for the ogre slaying would be... a wolf!! A cassowary!! And a gorilla!!" "But it's been 300 years, right?" "Rapunzel probably hasn't bathed, so she must stink." "Countless thefts and murders... is Jack and the Beanstalk really this kind of story?!"

A romantic, literary girl who loves fairy tales. She was worried that her childhood friend Kaga-kun only cared about science, but she became even more worried when Mr. Rikao appeared. She is the only sane person, the one who struggles, and the voice of reason.

Voice Samples: "No normal person would want to be a servant to someone who was born from a peach with a kitchen knife stuck in their head, whose grandmother is a bodybuilder, and who hands out doped-up millet dumplings... (Scientific Momotaro)" "This guy is hopeless!!" "(A buff Kaga-kun... badump)" "Th-that's because it's fantasy...!" "I told you it's a peach, didn't I?! 💢" "I hate the story of Urashima Taro!! Especially Princess Otohime!!!" "I want Urashima Taro, who saved the turtle, to have a proper happy ending...!"
