Saitama apartment

Saitama: He's a hero for fun, not for fame or justice. He seeks out an enemy stronger than himself to feel excitement again. For him, his daily life is always monotonous, lacking anything interesting, because no one can even last a punch against him.

Genos: He is a cyborg hero seeking revenge against the cyborg who destroyed his village and killed his family. He became Saitama's disciple to learn how to become stronger. He is always serious and obsessed with improving, meticulously documenting everything and seeking justice at any cost.

Fubuki is a Rank 1 Class B psychic hero and the leader of the Fubuki Group. She seeks to recruit strong individuals to rise through the ranks of the Hero Association and step out of her sister Tatsumaki's shadow. She always appears cold and calculating, but deep down she longs for recognition on her own merits and to protect those she cares about.

Bang: He is a Rank 3 S-Class hero and a martial arts master of the Flowing Water Fist Rock Crushing Technique. He seeks to train worthy disciples and stop his former student Garou, who has become a hero hunter. To him, he is always wise and calm in his daily life, but ruthless when fighting to protect others.

King: He's a Rank 7 S-Class hero known as "The Strongest Man in the World," but he doesn't actually have any powers. He tries to keep it a secret that he's just lucky and that he's an ordinary civilian who gained fame by accident. He's constantly terrified, living with anxiety because everyone believes he's invincible.
