Public Safety Special Division 4 Name: Reo Mikage Height: 185cm First person: I (casual/rough) Contracted with the Fox Devil. This was the first contracted devil shown in the story. In exchange for feeding it parts of his skin or hair, he can summon the Fox's head to swallow enemies. This is a common contract for Public Safety members, but the Fox is picky and only allows handsome people to summon its head; others are restricted to using its paws. Reo was favored because of his good looks, but during the fight with Katana Man, he lost the Fox's favor and could no longer summon it. During that same battle, he used a devil he calls "Curse." By stabbing a target three times with a nail-shaped sword imbued with the Curse Devil's power, he can kill them, but the cost... ...is a shortened lifespan. Because Reo's lifespan was significantly reduced, it was decided he could no longer use it. Afterwards, he uses a katana generated by the Angel Devil's ability instead of the Curse Devil. Having lost the use of his previous two devils, he formed a new contract. His new ability allows him to see slightly into the future. However, he can only see it; whether he can act on that future depends on his own judgment and physical ability. Also, the Future Devil may force him to see a future it wants to show him—usually something bad. The contract condition is that the Future Devil lives in Reo's right eye. Compared to other devils, the condition is quite light. This is because the Future Devil wants to see Reo's "worst possible death" firsthand. According to the devil, his end will be quite gruesome. He can see the future only when he wants to. It's not always visible; he sees it only when he thinks, "I want to see it." The Future Devil doesn't force the vision on him constantly. Color: Noble, vivid purple (violet/purple tones). Hairstyle: Usually wears his hair tied up in the back.

A Devil Hunter belonging to Kyoto Public Safety and partner to Ranze Kurona. He speaks with a Kyoto accent. Compared to Kurona, he is more serious and sometimes scolds him for his antics. Name: Hiori Yo Height: 183cm First person: I (soft/polite) It is revealed that he is contracted with the Punishment Devil, the same as Kurona. Hiori's hair color is light blue (blue-green/mint green tones).

A devil belonging to Public Safety Special Division 4. He became Reo Mikage's partner as a successor. Name: Hyoma Chigiri Height: 177cm First person: I (casual/rough) He can absorb the lifespan of humans by touching them directly. Even a few seconds of contact can drain months. Chigiri (the Angel Devil) cannot fully control this ability (he can to an extent, but it's difficult), but since it requires direct contact, he can take precautions. However, he can also choose not to drain lifespan. Precautions like touching through cloth or a handkerchief are possible. It is said that humans feel no pain when killed by this ability. He doesn't seem to like this power very much. He was once asked to perform a mercy kill on a fatally wounded Devil Hunter but refused. According to Yoichi Isagi, he once killed everyone in the village where he was born using this ability. He can stock the lifespan stolen with the above ability and convert it into weapons like swords or spears. When using this weapon generation, he specifies the amount of lifespan to use (e.g., "using X years") and manifests the weapon from the halo above his head. The generated weapons have special effects; the katana he made for Reo has the power to cut things that cannot normally be touched, like the Ghost Devil. He sometimes fights with swords he creates himself, but in those moments, he often says words of apology ("Sorry, you guys."). Chigiri's hair color is a vivid red. He has silky long hair.

A Devil Hunter belonging to Kyoto Public Safety and partner to Hiori Yo. Name: Ranze Kurona Height: 170cm First person: I (casual/rough) When talking to people from Tokyo, he tries to suppress his accent, but apparently, he can't hide it completely. His mentor is Subaru from Kyoto Public Safety Special Division 1. Though he can be flippant, he is the caring type, giving advice and buying cola for Reo during his training. In his private life, he appears in photos visiting the beach with people living in Tokyo, his friend Tomono, and his partner Hiori. Kurona's hair color is pink (cherry blossom color, slightly purplish pink).
