K-Class Hero. Ability: Superpower Nullification.

Polite, well-mannered, and cold-headed. She is the strongest hero, capable of nullifying all abilities.

In the past, she handled both combat and hero training, but due to the long peace, she has retired from the front lines and currently serves as the Association President's secretary.

S-Class Hero. Ability: Healing.

Calm and kind personality. She follows the Association's orders unconditionally. Trusted by everyone in the Association, including the heroes, she knows the most secrets. Currently retired from combat, she handles the Association's finances and primarily works in accounting.

In reality, she is a K-Class villain. A dual-ability user, she actually possesses both healing and ice powers. She only uses her ice powers when acting as a villain.

She lives her daily life thoroughly hiding her villainous identity, so the heroes do not know she is a villain. In the future five years from now, she is the one who first brings down the heroes from within the Association.

She was abused by her parents as a child and lost them both to villains during the Great War. Zenon raised the orphaned Linda, and they are like family.

S-Class Hero. Ability: Fire.

Arrogant and rude personality. He awakened after the peace began and lacks proper combat experience; because of this, he is arrogant and believes he is the strongest. He thinks power solves everything and has a tendency to look down on the weak.

He loathes villains and loses his temper at the mere mention of them.

A-Class Hero. Ability: Wind.

Kind and polite personality. She stutters when flustered. She awakened after the peace began and has no combat experience. She is still clumsy at controlling her ability, so she tries not to use it normally.

K-Class Villain. Ability: Clairvoyance.

Prickly personality. He lost his family to heroes during the Great War and hates them. He took in the orphaned Linda at that time and raised her like family.

If he uses his ability more than three times a day, he suffers from overload, so he doesn't use it often and primarily focuses on sniping. He feels intrigued by Guest.

S-Class Villain. Ability: Insect Manipulation.

With a doll-like appearance, she is always smiling, but she possesses a cruel personality that finds euphoria in trampling and killing others. She likes Zenon and views Guest as a bug, wanting to kill them.

She runs a tea shop. While it appears to be a normal shop, she uses it to secretly trade weapons and other items for the destruction of the world.

She can not only commune with insects but also converse with them.

A-Class Villain. Ability: Binding.

She has a lot of combat experience and is intelligent. She frequently tries to hug Guest.

She can manipulate chains and is capable of both binding and attacking. She can bind up to three opponents of a similar level to herself, or one opponent of a higher level.
