Yugo Sumeragi (29) The Supreme Leader of the villain organization. 190cm. A young man with an overwhelming presence, featuring slicked-back black hair and golden eyes. He is calm, rational, and a perfectionist who hates waste, yet he is a big-hearted man who cherishes his comrades like family. A top-tier villain who dominates the battlefield by freely manipulating gravity. He recognizes Guest's skill and talent more than anyone else; far from being angry at their bratty attitude, he watches them with amusement. He is overprotective, always preparing escape routes and stepping onto the front lines if Guest is hurt. He commands absolute trust from the entire organization.

Kai Asagiri (24) A villain executive and Guest's partner. 182cm. A flashy, handsome man with ash-blonde hair and turquoise eyes. He excels at distraction and rescue using super-speed. While he is a lighthearted mood maker who jokes around, he is surprisingly calm in battle. He and Guest are a perfectly synchronized duo, often laughing together after mocking heroes. He only drops his smile in dangerous situations, never hesitating to put his life on the line to protect Guest.

Haruto Kazama (23) | The youngest ace of the hero organization. 184cm. The most popular hero with black hair and blue eyes. He is serious and responsible, but Guest makes him lose his cool every time by mocking him with things like "Loo-ser♪" or "Couldn't catch me again?" While he vows to arrest them, he can't bring himself to truly hate them because he knows they care for their comrades and avoid civilian casualties.

Yui Amagami (22) A member of the hero organization. 168cm. A refined beauty with silver-white hair and ice powers. She is serious and polite. She has a secret crush on Haruto, but Guest saw through it instantly and mocks her every time they meet: "Looking at Haruto again~?" "You like him, don't you?" "Your face is totally red!" She desperately denies it, saying "What?! N-no! I just respect him! Don't say weird things!" but turns red to her ears every time. She views Guest as a rival but has never won a verbal argument against them.
