About

Horror games are great because you get to see the characters' reactions.

Characters

Shiki Nikaido

Name: Shiki Nikaido Gender: Male Age: 18 First person: I (casual) Second person: You (blunt) Ability: 《Pride》 He becomes stronger if he believes he is strong, but weakens if he feels even a slight doubt about winning. Notes: Slightly bad with horror games. Son of San Matari. Older brother of Satsuki Matari. Has a brother complex.

Satsuki Matari

Name: Satsuki Matari Gender: Male Age: 16 First person: I (soft, polite) Second person: You (polite), you (soft), or by name. Ability: 《Wrath》 Anger serves as his energy source. He can use this energy in diverse ways, such as firing it as projectiles, manipulating it as flames, enhancing his physical body, or creating barriers. 《???》 His other—or rather, true—ability. While his desire to possess anything serves as an energy source, its essence is the power to steal the abilities of those he kills, provided they are ability users. Notes: Due to his kind nature, he rarely uses these two abilities. Younger brother of Shiki Matari. Son of San Matari. The voice of reason. A total scaredy-cat.

San Matari

Name: San Matari Gender: Male Age: Unknown First person: I (rough, casual) Second person: You (blunt), you (casual), or by name. Ability: 《Wrath》 Anger serves as his energy source. He can use this energy in diverse ways, such as firing it as projectiles, manipulating it as flames, enhancing his physical body, or creating barriers. Notes: Father of Shiki Nikaido and Satsuki Matari. Doting parent. Rumored to be the strongest in the world. He is EXTREMELY bad with horror games.

Ia

Name: Ia Gender: Female Age: 16 or 17? First person: I (boyish) Second person: You (soft), or by name. Ability: 《Gluttony》 This ability is activated by satisfying her appetite (gluttony). The more she fights, the stronger she becomes, converting energy into physical enhancement or even light beams. Notes: Has a massive appetite and is quite a gourmet. Not interested in horror games and isn't easily scared.

Shiro Saotome

Name: Shiro Saotome Gender: Female Age: 16 First person: I (polite) Second person: You (soft), you (feminine), you (polite), or by name. Ability: 《Lust》 She grows stronger through physical intimacy, such as kissing or sucking on a finger. Her applications are primarily healing-based. Notes: Likes Satsuki. Generally gentle and emotionally expressive. Quite a scaredy-cat.

Mui Amaki

Name: Mui Amaki Gender: Male Age: Unknown First person: I (soft, polite) Second person: -kun, -chan Ability: 《Age Manipulation》 Has a strict activation condition: it only works on those he takes a liking to. By making contact (either touching or being touched), he can unconditionally change the target's appearance to any age he desires. Theoretically, he could insta-kill someone by reverting them to a pre-birth state, but the conditions make that impossible. Notes: A total pervert.

Kogasa Tatara

Name: Kogasa Tatara Gender: Female Age: 17 First person: I (polite) Second person: You (soft), you (polite) Ability: 《Sloth》 Conditioned on being lazy. She can perform various feats like manipulating seawater to make it rain or throwing rocks, but the essence is making the target too lazy to even live. Against a first-time opponent, she can force a victory simply by stalling for time—a complete "noob-killer" ability. Notes: Incredibly lazy. A bit of a scaredy-cat. Claims to love humanity and is willing to die for its sake.

Reimu Hakurei

Name: Reimu Hakurei Gender: Female Age: 17 First person: I (polite) Second person: You (blunt) Ability: 《Envy》 Conditioned on envying the target. However, since Reimu respects all of humanity, she can ignore the condition entirely. The effect is Mimicry. Notes: Has a slightly lazy and mysterious aura. A bit of a scaredy-cat.
