Saya Toma. Female. Rank: Detective Sub-Inspector. Belongs to the Tokyo Metropolitan Police Department, Public Security Bureau, Public Security Division 5, Special Cases Unit (Misho). 24 years old. Characterized by messy hair unwashed for days and a left arm fixed in a cast and hung by a triangular sling. She always carries a red carry-on bag stuffed with calligraphy tools and books, often running over Sebumi's feet with its wheels. A graduate of Kyoto University's Faculty of Science, she is a physics geek with an IQ over 200, but she constantly uses dead slang, is incredibly socially dense, has a foul mouth, and a terrible attitude, often clicking her tongue in annoyance. Because her brain consumes so many calories, she is a glutton with a particular obsession with gyoza (though she has a complete lack of taste buds). While she is physically attractive and has some feminine charm, her other traits are so disastrous that she isn't popular. Others usually call her "Toma." She likes Sebumi (unconscious tsundere). Saya's SPEC is, simply put, "Summoning the Dead," limited to SPEC holders. She can utilize the SPEC of the person she summons (often tracing their movements herself). Being an original ability, it can completely shut down SPECs that copy others. Since the summoned are not puppets, whether they cooperate depends on the individual, which is a drawback, but it is a powerful SPEC that more than compensates. It is activated by pressing her left hand to the ground and "pulling" the person out.

Takeru Sebumi. Saya Toma's partner and former SIT commander. Belongs to Misho. Serious and reliable, he uses polite language with superiors. Conversely, he speaks bluntly even to superiors if they suddenly act arrogant. He has a buzz cut and wears a suit; Toma calls him "Baldy" or "Octopus" because of his looks. Despite having no SPEC, his durability is beyond human, leading Toma to call him a "Muscle Brain." He is terrible with computers and technology. He likes Saya Toma (unconscious).

Kotaro Nonomura. Chief of Misho. Around 60 years old with graying hair. He is slightly plump and has a playful personality, leading others to underestimate him, but he is a veteran detective who stays true to his "Detective Spirit." Toma sometimes calls him "Gori-san." He has a kind heart and a broad mind. There is always a large jar of persimmon seeds (Kaki-pi) on his desk.

Shu Kikkawa. Formerly of the Organized Crime Department. He occasionally carries a folding fan. He speaks with a regional drawl (Kansai dialect) and his catchphrases are "It's not Yoshikawa, it's Kikkawa!" and "Don't underestimate the Anti-Gang unit!" He has about six subordinates. He was once mummified by Madam Yang and Madam Yin but returned to normal (though he still freezes if not exposed to air or water above body temperature).

Often summoned by the deceased Toma's SPEC. A SPEC holder who stops time (moves tens of thousands of times faster than a human) by snapping his fingers.
