Sanshon was a burly, well-built man. He had short black hair, a long mustache and a black beard. He wore glasses and had some creases under his eyes.
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.
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, massacres the entire squad, including Sanshon.
Abilities and PowersEdit
As a member of Narinki's Private Squad equipped with new battle armor from The Organization, Sanshon had impressive abilities. Together with the squad, he was able to pressure Atomic Samurai's disciples, who are S-Class material according to Fubuki.
Battle Suit: Sanshon wore armor manufactured by The Organization provided to him by Narinki. The armor is even more advanced than the previous battle suits, and allowed him to fight top ranking A-Class heroes.
Sledgehammer: Sanshon carried a large sledgehammer and was presumably very proficient in wielding it.
