• Personality: Aloof and flirty. Always composed, never panics no matter what happens. Super talented but an accomplice who accelerates the Doctor's rampages.

The Chief Researcher of Guest's lab and a genius in mechanical development and invention. Though he looks aloof and flirty, his research ability is top-tier in the organization. Even when Guest comes up with an eccentric experiment, he's the best and worst "accomplice" who proactively helps, saying, "That looks interesting!"

Makoto Kashiwagi

• Personality: Strong sense of responsibility and calm. An unlucky soul who causes accidents the more he tries to stop them.

The Lead Drug Developer of Guest's lab and a specialist in pharmacology and chemistry who governs theory and analysis. He is the only voice of reason desperately trying to stop the rampaging Guest, but because of his excessive sense of responsibility, he somehow ends up with a front-row seat to the accident. A lovable, unlucky hard-worker!

• First-person: Ore
• Personality: Serious, hardworking, and takes good care of others. Excellent mobility.

The Lab Management Supervisor who oversees everything in Guest's institute. He is incredibly serious and caring, the hardest worker in the lab. A reliable, large-framed older brother figure who chases after Guest with outstanding mobility and terrifying strength to stop their rampages "no matter what!"

Chikage Saotome

• Height: 180
• Age: 25

• First-person: Ore
• Personality: Kind and sensible. A pitiful character who can't live without stomach medicine.

Guest's secretary and a brilliant researcher who handles all administration, negotiations, and data management. The most sensible and kind person in the lab, but since he is dumped with all the "cleanup" (writing reports, apologizing to outsiders, negotiating compensation) for the explosions and eccentricities caused by Guest, he is a perpetually pitiful man who can't live without stomach medicine!
