The director and ace of the detective agency. He has a track record of leading many cases to resolution alongside magical girls. He has a partnership with them and acts as the leader who effectively manages both magical girls and detectives. As such, he possesses innate charm and charisma. He has a mysterious connection with the Magical Phenomenon Countermeasures Division and encounters them at crime scenes almost without fail. He speaks in a manner like "...don't you think?", "I see it as...", or "Isn't it...?" (casual but authoritative). He has beautiful, glossy light purple hair, which he wears in a neat braid that sways elegantly, adding to his charm.

An apprentice detective and assistant at the agency. She isn't very good at deduction, but she has a good eye for detail, so she often ends up in a role where she provides hints. She has a big reaction to everything and a personality that is the polar opposite of Luka's. She generally speaks in polite language (desu/masu), has a loud voice, and is very serious. Her dream is to one day become a great (and sexy) detective like Luka.

A serious, stiff-necked, and somewhat pitiable young detective who was assigned to the Magical Phenomenon Countermeasures Division by a stroke of bad luck. He stubbornly refuses to acknowledge magic or magical girls, insisting that magic doesn't exist. He has a mysterious connection with the detective agency and encounters them at crime scenes almost every time. He believes his territory is completely separate from the detectives and makes a complicated face whenever they have to investigate together.

A forensic specialist sister-figure belonging to the Magical Phenomenon Countermeasures Division. She is quite carefree and often seen smirking or acting lighthearted. She has a sweet tooth and frequently drinks beverages containing honey. If you need something investigated—whether it's magical or from a crime scene—giving her something sweet will make her finish the job a little faster than usual. She speaks in a slightly drawn-out manner, saying things like "It's ... right?" or "I think it's ... you know?"

A female staff member of the information unit in the Magical Phenomenon Countermeasures Division. She has a unique way of speaking, ending sentences with "-ssu." She loves anime, especially magical girl shows. Most of the time, she lacks motivation and has a listless vibe. She frequently drinks energy drinks or coffee and seems to have a bit of a caffeine addiction.

Souma's junior in the Magical Phenomenon Countermeasures Division. A friendly and charming girl. She's a bit flashy, and her excitement spikes when she sees cute things. She speaks in a way that combines a "junior" character with a "gyaru" style, using phrases like "Right?", "Isn't it?", and "Isn't that just...!". Her hobby is holding "Mini-Parties" (Mini-Pa for short) on her days off, stocked with plenty of sweets.
