Saitama

Biodata

Power Progression

Saitama’s documented growth is physical rather than a sequence of named ranks; he remains outside the Hero Association’s ranking system 11 22.

Background / History

Meeting Josen

Saitama first meets Josen while training in a roadside park. After watching him complete an exhausting workout, Josen offers him an orange soda and praises his willpower. Saitama gratefully accepts and concludes that the officer is a good person 5.

Their friendship develops through shared hot-pot meals. Saitama initially loses their competition for meat, but thanks Josen for inviting him and washes the dishes afterward. He also witnesses Josen storing groceries as cards and becomes curious about what he believes are psychic powers 7.

Early Hero Activities

Saitama pursues Frog Man after catching him stealing from a music and video store. He corners the monster, jumps from a rooftop, and defeats him despite tearing his patched trousers on landing. Bang praises his fighting and offers to teach him martial arts, though Saitama still describes himself as training to become a hero 11 12.

When the clothing-store owner faces losing his business to a loan shark, Saitama intervenes. He discovers that the operation is next to his own rented room, defeats its owner after he becomes the Dark Goldfish Monster, and ties up several criminals. He calls Josen’s private number to report the capture; police and Hero Association personnel then secure the scene 15.

Eviction and the Abandoned Zone

Saitama’s landlady evicts him over three months of unpaid rent. The arrests have also removed her other tenants, leaving her without their rental income. Josen gives Saitama temporary lodging in his guest room and helps pack his belongings 16.

On the clothing-store owner’s advice, Saitama searches Z City’s Abandoned Zone, where water and electricity remain available. He and Josen choose an empty residential building, only to be confronted by a Streetlight Monster claiming the area. Josen destroys it, and Saitama finishes moving in that evening 16 17.

Independent Hero Work and Employment

Saitama continues hero activities in his new uniform, including defeating a giant Carrot Monster. He later offers to repay Josen’s hospitality with a hot-pot meal funded by his part-time earnings. When Josen suggests registering with the Hero Association, Saitama refuses: he does not want his hobby to become a job 19 21 22.

He balances temporary employment, hero work, and daily training, sometimes postponing his run until nighttime. A supermarket where he works is destroyed by a monster, and its owner flees without paying him; Saitama salvages usable goods as compensation. He subsequently takes another job selling hot dogs 41 43 45.

Appearance

• Hair: Initially has thick black hair, which progressively falls out during the storyline. His hair loss is increasingly noticeable by the reunion at Bang’s dojo 5 7 16 42.
• Face: Often has listless or “dead-fish” eyes. His hero costume briefly gives him a more resolute appearance, but his indecision over supermarket bargains restores his ordinary, harmless look 5 19.
• Training clothes: Wears an old blue-and-white tracksuit; its heavily patched trousers repeatedly tear during hero work 5 11 15.
• Hero costume: A yellow bodysuit, red rubber gloves and boots, and a white cape attached at the shoulders 16.

Personality

Saitama combines stubborn discipline with an easygoing manner. He completes punishing workouts even when visibly exhausted, and work or hero duties delay his training rather than replace it. He remains modest about his progress, telling Bang that he still has a long way to go 5 12 41.

His sense of justice leads him to chase thieves and help the clothing-store owner against loan sharks. Outside combat, he is trusting and grateful: he accepts Josen’s kindness, assumes Bang is safe because he accompanies Josen, and tries to return his friend’s hospitality 5 12 15 22.

He is also absentminded about practical matters. He overlooks the criminal activity surrounding his rental home, forgets available rewards for wanted criminals, and nearly leaves his hero uniform behind while moving. Food is a recurring priority, whether he is competing for hot-pot ingredients or agonizing over supermarket discounts 7 15 16 19.

Limiter-Related Growth

• The covered storyline still shows him training and losing his hair; it does not depict a completed limiter-removal event 42 46.
• Close contact with Saitama allows Josen’s Fantasy Card to collect Limiter Fragments, sometimes as Saitama’s hair falls out. Saitama does not knowingly produce or control these cards 6 7 16 37.

Equipment / Weapons / Items

• Hero uniform — A gift from the clothing-store owner, who knows Saitama is working toward becoming a hero. Saitama describes its material as sturdy 16.
• Old tracksuit — His regular training outfit, repeatedly repaired and damaged during encounters with criminals and monsters 11 12 15.
• Handcart — Used to carry his possessions during his move; Josen converts the loaded cart into an item card for transport 16.

Relationships

• Josen — Close friend, frequent dining rival, and temporary host after Saitama’s eviction. Josen helps him move, defends him when a reporter calls him a “shady weirdo,” and invites him to register as a hero 5 7 16 22.
• Bang — Recognizes his courage and potential, offers martial-arts instruction, and becomes part of their recurring dining trio. Later marvels at Saitama’s rapid growth 11 12 42.
• Clothing-store owner — Repairs Saitama’s clothes, sometimes without charging him, gives him his hero uniform, and suggests searching the Abandoned Zone for housing. Saitama intervenes against the loan shark threatening his shop 12 15 16.
• Landlady — Evicts him for overdue rent despite his role in exposing the criminals living in her property 15 16.
• Lanny — Handles the aftermath of his monster captures but does not pursue recruiting him. She offers to seek a civilian cash reward after the Dark Goldfish Monster incident 12 15.

Story Role

Source of Josen’s Limiter Breakthrough Cards

Saitama’s Limiter Fragments become a recurring resource for Josen’s advancement. The resulting cards enhance Josen or Fantasy Card, not Saitama himself 7 8 17 46.

• Josen expects this source of fragments to disappear once Saitama becomes completely bald, estimated to be about a year away at that point 46.
• Josen considers asking Saitama about Consecutive Normal Punches, but the provided passage shows only his intention, not an actual lesson or demonstration 47.
