Katatsumuri Choujin A

Katatsumuri Choujin A is opportunistic and deceptive. He and his partner pose as illicit sellers willing to provide whatever visitors to their shop request.

The pair use that promise to lure potential victims into a vulnerable position before attacking. Their behavior fits the predatory environment of the Old Market, where conventional laws offer little protection.

The manga establishes little individual personality separating one Snail Choujin from the other.

Katatsumuri Choujin A can transform portions of his body with snail characteristics. His hands adhere to surfaces strongly enough for him to scale walls and move along ceilings.

He can extend his eyes outward on stalks, increasing the distinctly snail-like qualities of his transformed anatomy.

He possesses Raise like other Choujin.

Katatsumuri Choujin A appears on the sixth day of Operation Old Market, when Tokio, Michael, and Michelangelo begin directly infiltrating Minami City's criminal marketplace.

The Snail Choujin approach the disguised Keepers and offer to sell them whatever they need, including the opium Yamato Mori is attempting to trace.

Once the trio enters their shop, the two criminals reveal the offer as a trap and attack. Tokio's improved combat ability allows him to dispose of the ambush quickly before pursuing the remaining leads in Minami.

Katatsumuri Choujin B is Katatsumuri Choujin A's partner in the Old Market. Together, the two lure customers into their shop before attacking them.

Tokio Kurohara encounters the pair while investigating Minami and overpowers their ambush after they transform.

Michael Es is caught in the surprise attack but uses his psychic defenses to protect Michelangelo Deroginev Cembaletta San Sei.
