Abilities and powers
History
Punk Hazard
At Punk Hazard Kin'emon explains that the distress signal came from centaur guys to their boss and that he began slicing centaurs while seeking his son Momonosuke. He realizes Momonosuke is still imprisoned in the facility after the children confirm more captives were held there. Kin'emon reacts with shock upon learning Law has become a Shichibukai.1
Dressrosa
Kin'emon experiences sudden upheaval when a massive factory structure erupts from the ground in Dressrosa amid explosions and smoke. The event creates an opportunity for escape from an underground prison as allies react with shock and gratitude. Kin'emon later questions the surrounding commotion while observing reactions to Usopp in the streets.7
During the Marine operation in Dressrosa Kin'emon remains calm at Kyros' house while others panic over the approaching forces. He notes that the group had prepared to depart and was only awaiting Luffy's awakening. Reports indicate the warriors intend to capture the pirates as the situation escalates.8
Zou
At Zou Kin'emon and Kanjuro tumble from the dragon down the elephant's leg after an unexpected collision with a small monkey. The crew calls out in alarm while the samurai assure them they are unharmed and urge the others to continue upward without delay. The climb proves exhausting for the dragon as the group presses on.9
Fleeing Wano
Kin'emon and his group fled Wano after being pursued for leaving the country which is also a crime. They split up to recruit allies with Kin'emon entrusting Kiku with gathering intel on the enemies and parting with Raizo to meet on Zou. The group shipwrecked due to lacking navigational skills and later parted with Kanjuro who was captured while trying to reach Momonosuke.10
Wano Country
In Wano Kin'emon stands with Inuarashi before a fish-like man who discusses the SMILE fruits and their effects on the people of Ebis u Town. The group learns these synthetic Devil Fruits grant feral powers but prevent swimming and were distributed to bolster Kaido's forces. Kin'emon hears details of the factory's destruction and the fruits' origins.11
Kin'emon stands firm at the harbor amid raging waves and debris declaring that the small number of allies allows an easy introduction to Kaido for a surprise strike to cut off his head. The group faces the absence of four thousand soldiers who failed to appear and resolves not to give up while alive. Kin'emon emphasizes the advantage of their limited size for the approach without detection.12
Tension rises when the retainers realize their strategy has grown stale and suspect an enemy informant among them. Kin'emon faces direct confrontation from the group urging him to take the lead in identifying and disposing of the traitor so that no one remains unable to move forward. The confrontation highlights the need for proactive action to resolve the internal threat.12
Relationships
Raizou
Kin'emon reunites with Raizou at Zou where the minks recognize the Kozuki clan crest on Raizou's back. The group examines ancient markings together and Kin'emon expresses relief that everyone remains unharmed. He later reacts to the minks' excitement over ninja techniques while Raizou attempts to calm the crowd.13
Momonosuke's sister
Kin'emon encounters Momonosuke's younger sister in a ruined building where Brook comments on her resemblance to a courtesan. She recalls cursing Brook after he requested to see her panties and later teases him about sleeping nearby. Kin'emon listens as she discusses the many offerings at the well and her cold night.15
Major battles
Onigashima
During the raid on Onigashima Kin'emon stands ready with other samurai as Kaido's dragon form soars above the dome.
