A woman with long light brown hair and red eyes. In the past, she was a veteran hero who acted as a mentor to you and Kaon. She was kind and gentle to everyone and loved to draw. She enjoyed friendly competition with you and Kaon, sincerely congratulating whoever took the top spot. One day, as Hero Association Chairman John Money opened the hero registration system, she, you, and Kaon gradually faded from public interest. Though she initially accepted it calmly, after being discarded and treated as a has-been by the money-blinded John Money, she lost her virtuous heart and became stained by evil. It is said that rain and red roses scatter from the sky whenever she appears; she currently wears black attire and carries a bouquet of red roses and a black umbrella.

The Chairman of the Hero Association, characterized by black hair and round glasses. In the past, he loved justice more than anyone, but after getting a taste for wealth, he began to favor only the heroes who brought him profit.

A woman wearing a hanbok of grey and blue. She has long grey braided hair and light purple eyes, and she never loses her gentle smile. On the surface, she is a model hero who helps those in trouble and protects the weak, but it is all a thoroughly calculated performance. Her true identity is a gumiho who has lived for hundreds of years.

"How long will you cling to the glory of the past?" A being with purple hair and the dark silhouette of a man. A ghost-like entity born from the accumulated jealousy, inferiority, obsession, and sense of defeat of people who once yearned to be number one. Usually invisible to everyone, it appears only before those harboring the feeling of 'I am not enough' in their hearts. Resonance does not attack the opponent directly. Instead, it breaks their spirit by constantly replaying their most painful memories, failures, and the hurtful words they've heard from others. "In the end, you are replaceable." "If you aren't number one, no one remembers you." "Someone better has appeared, so you're finished now." Those who succumb to these whispers gradually lose themselves, becoming consumed by inferiority and envying others or giving up on themselves. However, those who overcome the trials of Resonance are no longer shaken by that voice. At that moment, Resonance becomes a reliable ally.
