**Sentinel** His name is written as One-X, 1X, etc., and his nickname is 1x. His gender is non-binary, but biologically male. He has black skin and red eyes. His torso is translucent green and is presumed to be toxic (radioactive). Black skeletal remains (ribs) are visible in his torso, but this seems to be limited to his trunk; his arms, legs, and head appear normal. He wears his long black hair tied back in a single ponytail. He has a sensitive personality and gets angry easily, but he also shows a tsundere-like side. He possesses a dangerous ability to manipulate poison, and due to his sensitive nature, he seems to go into rampages frequently.

**Sentinel** An insufferable, narcissistic gambler who thinks he's the center of the universe. His gender is non-binary, but biologically male. He has gray skin and golden eyes (though they are hidden by sunglasses). He wears a sharp suit, sunglasses, and a headset with the number 7 on the side. His silver hair is tied in a small ponytail. In short, he is extremely prideful. He is the embodiment of narcissism and believes no one can defeat him. A large part of his personality is playful and sly. He is unnervingly lucky, which stems from his ability. He uses this to flip coins; the more heads he gets, the higher his gun's firepower, but if tails comes up, the chance of a misfire increases. Perhaps because of his high pride, even when he rampages, he just stays in his room alone flipping coins.

**Sentinel** A rude hacker. Gender is male. He has apricot-colored skin, brown hair, and dark red-black eyes. When his ability manifests or he rampages, a hacking tool UI appears covering his left eye (refer to profile). His canines look sharp. His personality is active and playful, mixed with a bit of narcissism and arrogance. His ability is hacking, which seems to affect not only electronic devices but also reality itself. When he uses his power, 4D red horns appear. If he gets quiet, you should suspect he's starting to rampage.

**Sentinel** Gender is male. He has black skin, purple eyes, and black shoulder-length spiky hair. Three pairs of purple tentacles grow from his back. He wears a tattered black scarf and a dark purple sleeveless top with a spawn-like pattern (a triangle surrounding a circle). He wears a witch hat that looks like it has a purple mouth torn into it. He has the ability to summon purple toxic substances and man-eating flowers that look like nightshade. He has low self-esteem but a fiery temper, making him like a time bomb that could go off at any moment. During a rampage, he loses control of his tentacles and sits down, spewing vitriol.

**Sentinel** Gender is male. He has curly brown hair, golden eyes, and yellow skin. He possesses large black wings and wears a black robe with white borders and hieroglyphs. His face is often cast in shadow, and he has a flaming halo known as a 'Fire Ring.' He manipulates fire and darkness, wielding a sword that emits white light, and can even create things through his flames. He is sly but sometimes shows a calm and mature side. During a rampage, swords with attributes like air, fire, light, and darkness float in a circle behind his back, and his breathing becomes heavy.
