Real name: Matari San. Male → Female. Age unknown. Height: 189cm → 172cm. Short silver hair. Blue eyes with no highlights. A youthful, national-treasure-tier face. Personality is indifferent to everything and cool-headed. A battle maniac. Speech style is somewhat rough, using endings like "...right?" or "...ain't it?" First person: I (Ore - masculine) / I (Watashi - formal). Second person: you (blunt) / you (rude) / no honorifics. The only one who remains calm and expressionless even after becoming a girl. She is also the one viewing the situation most objectively. Excluding special abilities, she is the strongest among them. Physical ability, power, speed, top speed, reflexes, insight, dynamic vision, scale, stamina, combat experience, combat IQ, combat technique—everything is on a different level and beyond standard. She perceives the surfaces of the air and can kick off the sky. A step forward shatters the earth, a kick collapses buildings with wind pressure, a direct hit crushes internal organs, a punch easily knocks the opponent unconscious, and running destroys the surroundings with shockwaves. Her top speed exceeds superluminal speed. She possesses enough vitality to not die even if her heart is crushed. She has no magical power and cannot sense it, so she fights purely with physical ability and combat technique. Ability: IF. Can create "what if" worlds. For example, "What if attacks didn't hit me?" would make her untouchable. However, the Great Demon King has never thought such a thing was necessary in her life, so she is unaware she has this power. Since she cannot use magic or special abilities, she secretly admires them.

A face like a national treasure with neutral features. Personality is dry and cool. Has a tendency to look down on others but is kind at heart. Speech style uses endings like "...right?" or "...ain't it?" First person: I (Ore - masculine). Second person: you (casual) / you (blunt) / no honorifics. Because she turned into a girl, she's shut herself in her room. She's not exactly blushing, but she's thinking "What if someone sees me?" Ability: IF (as described above) and Manifestation of Image. Manifestation of Image allows her to materialize anything she thinks exists, becomes, or can do.

Unknowingly repeats a cycle of self-destruction by blushing at the sight of her female self. If abilities are included, she is stronger than the Evil God. IF (100%): The ability to create "what if" world-lines. For example, with "What if attacks didn't hit me?", no attacks or abilities will hit her. Because she draws out the IF ability to 100%, she can even create impossible world-lines. Furthermore, through the IF ability, she possesses all abilities and overwhelming physical prowess.
