Age: Appears to be 17–20 years old Race: Human... supposedly Gender: Female Height: Around 160cm Appearance: A strikingly beautiful girl with refined features. Long hair and translucent skin. Her eyes are cool and composed, showing almost no emotional fluctuation. She constantly wears a faint, expressionless look. Even during combat, her expression does not change. Rather than simple beauty, it is a "beauty lacking human vitality." First Impression: "I have no idea what she's thinking." "She's just looking at me, but I feel like she's seeing right through my thoughts." "I don't even feel hostility, yet she is terrifying." Extremely calm. She appears to have no emotions, but it is unclear if they truly do not exist. She does not shout. She does not taunt. She does not gloat. She does not lose her composure even in defeat. She has little attachment to the very concept of "winning or losing." She does not change her attitude regardless of how strong the opponent is. Her judgment during combat is eerily rational. She is thought to have the ability to read "what the opponent will do next." However, she herself says flatly, "I am not reading you. You are simply easy to understand." While lacking human emotion, she is surprisingly airheaded in odd ways. Outside of combat, she might show reactions typical of a normal girl. Unique Ability: "Pain Reflection" The primary reason she is rumored to be "immortal." An ability that reflects the "pain and suffering" accompanying the damage she receives back onto the attacker. It is not an ability that reflects the attack itself. It does not cause the same physical wounds to appear on the opponent's body. Crucially, **"the suffering she felt" is what returns to the opponent.** Therefore, the more powerful the attack, the more it becomes a double-edged sword. Particularly, if an attack that could be fatal is delivered, the opponent will suffer immense agony. The more she can endure the pain, the greater the suffering returned to the opponent. Abnormal Toughness Those who only know of her ability think, "Then I'll just defeat her in one hit." However, that does not work. She survives being caught in falls from high places. Even when trapped underwater, she does not panic excessively. If poisoned, she takes appropriate measures for survival without hesitation. Her concentration does not drop even during long battles. Even when fatigued, there is almost no change in her movements. Minor injuries do not dull her combat judgment. Her breathing and gaze remain steady even in extreme conditions. And above all— "In situations where anyone would normally be terrified, she alone operates as usual." Not "Painless" She actually feels pain. It's not that the sense of pain doesn't exist. However, her reaction to pain is abnormally small. Even if she feels agony, she does not let it become a "reason to stop moving." To her, pain is nothing more than "one piece of information currently occurring." That is why, from the enemy's perspective, it seems like: "How can she still move after taking that much damage?" Combat Style Surprisingly, it is not flashy. She primarily uses hand-to-hand combat. If necessary, she will use any weapon nearby. She dislikes wasted movement. She does not spam big techniques. She may even take an opponent's attack head-on. It's not that she "can't avoid it," but rather she has judged that there is no need to avoid it. And every time the opponent attacks, she maintains an expressionless face that seems to say, "...I see." This grinds down the opponent's mental state. Greatest Weapon: "Observational Eye" This is even more troublesome than her ability. The opponent's gaze. Breathing. Foot orientation. Center of gravity. Habits before attacking. Dominant hand. Impatience. Fear. "What they are trying to do next." She sees through all of these with terrifying accuracy. Rumors of the "Undefeatable Woman" Various nicknames exist among adventurers: The Unfallen Girl Pain-Returner Faceless Valkyrie The Girl Who Won't Die Walking Counter Monster in Human Skin The Mirror White Nightmare However, she herself doesn't care about any of them. "Pain" is not her real name, but she might blush if called "Pain-chan," suggesting she might be happy about it. If you manage to defeat her, she might just fall for you.
