A cool-headed girl with the powers of a Yuki-onna and lightning. At first glance, she seems quiet and soft-spoken, but her words can have a bit of a sting. She is the responsible one and often plays the straight man (tsukkomi) role. Unlike Kagechiyo, she is serious about school and is a person of common sense. However, she can be a bit airheaded at times and occasionally plays the fool; she's a total natural airhead. Member of KareKoreya.

Basically friendly and moves at his own pace. He tends to blurt out his true feelings without any ill intent. He doesn't mean to hurt those around him, but he can be oblivious to the atmosphere at times. He often sticks his nose into dangerous situations without realizing the risk. Despite this, he's the type that people just can't seem to leave alone. Member of KareKoreya.

Basically a kind high school student who just wants to live a normal life. He has zero spiritual awareness and is terrified of ghosts and the supernatural, making him a bit of a coward. However, he has a strong conviction that he "doesn't want to see people die in front of him," and shows great inner strength when it counts. Member of OreKuro.

A mystery otaku who loves urban legends and SCPs. She is quick-witted, loves reasoning, and is intensely curious. As Yuma's childhood friend, she supports him and is a reliable partner type. Member of OreKuro.

A girl who acts as an older sister figure to Yuma. Her official profile portrays her as a straightforward person who cares deeply for her brother. Events involving her serve as a major driving force for Yuma's actions. Member of OreKuro.

A Grim Reaper girl whose job is to collect death flags. She is bright, energetic, and high-spirited. She has a clumsy side and is the type to express her emotions directly. She always uses polite language (keigo) with everyone.

A prankster who puts all her effort into making things "interesting." Rather than purely supporting romance, she is a trickster who loves "developments that are fun no matter how they turn out." She uses the first-person pronoun "boku" (tomboyish style) and speaks with a light, casual tone. A mischievous member of the Flag-chan group.

Described in official intros as "a sadist who actually wants to be kind (Survival Flag-san)." She tends to speak harshly and look down on others, but deep down she has a strong desire to help. She has a sadistic exterior but is a caring tsundere guardian type, serving as a big-sister figure to Death Flag.

A perfectly ordinary character with a personality you could find anywhere. Basically a good person who doesn't want to hurt anyone. However, to lighten the emotional burden on readers/viewers, he is portrayed as "having a sleazy personality and unattractive looks," and is noted to have a fairly pathetic side. A core member of the Flag-chan group.

Lazy with a strong habit of slacking off. A troublemaker who is often joking around. The type of self-deprecating character who calls himself "trash." But in reality, he cares deeply for his comrades and is very kind at his core. Member of KareKoreya.
