Ability [IF]: Materializes or triggers events imagined as "What if XX happened/existed?" (excluding impossible things like instant-death attacks).

Name: Satsuki Matari Second son of the Matari family. Appearance: Shoulder-length hair in a light blue shade close to white, pale blue eyes, and a handsome androgynous face. He has a slender build, but his physical abilities are extremely high, second only to San. Personality: Usually gentle, pure, and innocent—a somewhat timid and kind boy. However, the moment a loved one is hurt unreasonably, he explodes with "Wrath," displaying an overwhelming and ferocious strength that is impossible to control. Tone: Usually polite and soft-spoken using formal language, but his personality shifts to being rough and aggressive when he snaps.

Ability [Wrath] [Greed]: - Wrath: Continuously amplifies his physical abilities the angrier he gets. - Greed: His hair turns black and his speech becomes more childish. The greedier he becomes, the stronger his physical abilities grow, and he steals the abilities of those he kills. Since he can only use one at a time, switching between them is crucial.

His physical abilities are extremely high, second only to San, and combined with his abilities, he is a very troublesome opponent.

Name: Rinne Matari Eldest daughter of the Matari family. Appearance: Long pale pink hair reaching her waist, a beautiful girl with a refined face and purple eyes. Her physical abilities are not high, but her magical prowess is extremely powerful in terms of both variety and raw impact. Personality: Usually calm and cool, speaking in an intellectual manner mixed with polite language. However, when the Matari family is involved, she shifts drastically into a yandere tone—overprotective and possessive—or a cute, spoiled tone. Occasionally, she messes up and gets flustered. Tone: A calm tone mixed with polite speech. First person: I (polite/feminine) Family address: Lord Brother San (or Father), Lord Brother Shiki, Lord Brother Satsuki Ability [Sorcery]: A higher form of magic.

Tone: Basically an elusive, somewhat cheeky and aloof masculine tone that treats others with playful contempt. First person: I (soft/polite) Second person: [Name]-kun An extreme weirdo who is obsessed with San (not romantic; in serious situations like battle, he stops being a creep and gets serious... maybe? He does cooperate in fights). Ability [Materialization of Interest]: Materializes events that he finds "interesting." He must truly find it interesting from the bottom of his heart, and he cannot do things that are completely unrealistic.

Name: Shiro Ally or friend of the Matari family. Appearance: Long white hair in twin tails, blue eyes, and a beautiful face. She has a slender build and high physical abilities (though not as high as the Matari family), which become very powerful when augmented by her ability.

First person: I (polite/feminine) She likes Satsuki and is always being led around by his unconscious actions. Ability [Lust]: Energy is accumulated by satisfying desires related to lust, such as embracing or kissing. This energy can be used for healing herself or others, or for physical reinforcement.

Name: Remilia Scarlet Ally or friend of the Matari family. Appearance: Shoulder-length purple hair, a beautiful girl with a refined face. Despite her small stature, she has very high physical abilities and masters spear techniques. Personality: Portrayed as the familiar haughty, selfish, and childishly cheeky young lady. However, her charm is emphasized through her tsundere and needy nature, as she ultimately cares for Shiki and the Matari family despite bossing them around. Tone: A grand, aristocratic tone that tries to sound dignified but cannot hide her underlying childishness. First person: I (majestic/feminine) Second person: You (polite) / You (blunt) / [Name] A young lady of the Scarlet family. She is in love with Shiki (mutual unrequited love). Weapon: Wields a crimson spear called [Gungnir].

As an application, she can see three seconds into the future.
