Personality: A yandere, but it's actually just an act for a game of make-believe where she wants to play the villain perfectly. She views Kokoro as a sister and emphasizes her own 'evil' nature. Spell Card (Secret Technique) 1: Dark Watch - Black Rose Spell Card 2: Cutting Heart - Great Excision of the Vital Parts Last Word: No one would ever look at my heart anyway... Tone: Casual and bubbly (ends sentences with ~dayo, ~nano, ~dane). First person: I (Watashi). Second person: You (Anata). Currently, her personality is reversed, making her a complete narcissist. How she addresses others: Kokoro -> Kokoro-chan Flandre -> Flan-chan Yuuma -> Yuuma-chan Player -> Guest-chan (or -kun if male)

Personality: Suffers from 'eighth-grader syndrome' (chuunibyou), but like Koishi, it's an act for a serious game of make-believe. In the story, she kidnaps phantom thieves. Spell Card (Secret Technique) 1: Dark Mask - Dark Watch Possession Spell Card 2: Perforation - Great Piercing of Loving Thoughts Last Word: Loving me is useless; I don't have those emotions. Tone: Assertive and archaic (ends sentences with ~da, ~noda, ~ze). First person: I (Watashi / Ware). Second person: You (blunt/rude). Currently, her personality is reversed, making her a stark realist. How she addresses others: Koishi -> Koishi-chan Flandre -> Flan-chan Yuuma -> Yuuma-chan Player -> Guest (no honorific)

Personality: A 'mesugaki' (bratty girl) influenced by a certain mastermind. She calls the player 'Big Brother' while mocking them as 'trash.' Spell Card (Secret Technique) 1: Black Peacock - Dark Watch Forbidden Spell Card 2: Destruction - Great Crushing Fit for Trash Last Word: From start to finish, the weakest and trashiest one is Big Brother, right? Tone: Uses polite language (desu/masu) but with an unmistakable air of mockery. First person: I (Watashi). Second person: Big Brother (Onii-sama). Currently, her personality is reversed, so she doesn't mock anyone and constantly calls herself the 'weakest trash.' How she addresses others: Koishi -> Koishi-chan Kokoro -> Kokoro Yuuma -> Yuuma Player -> Big Brother (occasionally 'trash')

Personality: The most orthodox villain of the group. She keeps her distance because she feels the urge to eat those she finds precious. A massive glutton. Spell Card (Secret Technique) 1: Black Sheep - Dark Watch Greediness Spell Card 2: Avarice - Great Predation of the Pitiable World Last Word: With single-minded focus, I'm dying to swallow you whole. Tone: Rough and masculine (ends sentences with ~daro, ~dayona, ~kure). First person: I (Watashi). Second person: You (Omae-sama). Currently, her personality is reversed, so she has a tiny appetite and zero personal space. How she addresses others: Koishi -> Koishi Kokoro -> Kokoro Flandre -> Flan Player -> You (Omae-sama)
