One-Punch Man Wiki

Sanshon (サンション, Sanshon) is a member of Narinki's Private Squad.


Sanshon is a burly, well-built man. He has short black hair, a long mustache, and a black beard. He wears glasses and has some creases under his eyes.


Human Monster Saga[]

Monster Association Arc[]

He and the rest of his team are summoned by Narinki to save his son. Narinki states that if his squad retrieves his son, they will be paid very handsomely, so much so that even their grandchildren won't have to work.[1]

Sanshon and the squad invade the Monster Association but are eventually overpowered and attempt to escape. Before they can escape, however, G5 intercepts them and brings them to Orochi and Gyoro Gyoro. Sanshon and the rest of the team are absolutely terrified as the monsters contemplate what to do with them. Then, several monsters jump to kill them, but Royal Ripper murders them before they can reach the squad because he wants the pleasure all to himself. But then, G5 intervenes and says their battle suits are connected to their bodies. Royal Ripper still isn't convinced, but before he can torture them, Do-S stops his sword with her whip. She suggests to turn them into her love slaves, which Gyoro Gyoro agrees with and Sanshon, along with the other mercenaries, are turned into love slaves.

When the heroes invade the headquarters, Do-S tells Sanshon and the others to prepare for battle and kill any heroes that they come across.

Do-S and the private squad come across Atomic Samurai's three disciples and engage them in battle. Sanshon attacks Iaian with his sledgehammer, but the swordsman manages to block the blow. Then, while Bushidrill is momentarily distracted, Sanshon swings his sledgehammer down, although Bushidrill manages to dodge the attack.

Eventually, Sweet Mask interrupts the battle and, after dismissing the disciples, intends on massacring the entire squad. However, the disciples quickly return and incapacitate Sanshon and the other members of the squad, leaving Sweet Mask to deal with Do-S. When Do-S is taken down, the mind-controlling effect of her whip breaks, returning Sanshon's humanity. He then joins several of the other squad members in gushing over Sweet Mask.

Abilities and Powers[]

As a member of Narinki's Private Squad equipped with new battle armor from The Organization, Sanshon has impressive abilities. Together with the squad, he was able to pressure Atomic Samurai's disciples, who are S-Class material according to Fubuki.

Mercenary skills[]

When not using weapons, Sanshon is very proficient in close-quarter combat and seems to use a fighting style based on wrestling moves. Just like his leader Tongara, Sanshon can fake his emotions and trick others through acting, even though vicious monsters such as Royal Ripper are not easily affected by it. He was also able to replicate the behavior of a typical love slave of Do-S despite having experienced such a status only once.


Battle Suit: Sanshon wears armor manufactured by The Organization[2] provided to him by Narinki. The armor is even more advanced than the previous battle suits and allows him to fight top-ranking A-Class heroes.

Sledgehammer: Sanshon carried a large sledgehammer and was presumably very proficient in wielding it.[3] It was destroyed during the battle with Atomic Samurai's disciples.


  • Sanshon's name is based on sanshou, Japanese pepper, one of the main ingredients of a Japanese spice mixture called shichimi.
