Karin/Plot

## Plot

### Episode 1

She is first seen with Shitan and Tsubaki as the archer helped kill a few soldiers during Fena, Salman and Otto's escape from Shangri-La, as she commented on the old men's poor sense of direction. She is then seen resting on a tall dead tree branch with Shitan, Kaede, Enju, Tsubaki and Makaba resting on the tree, as they witnessed Yukimaru knock out Fena during their reunion, with Karin commenting on the moment being ruined by their leader.

### Episode 2

As Fena was arriving at Goblin Island, she was seen with Yukimaru and the other samurai watching her, Salman and Otto arrive before the seven disappear out of sight. The next morning, she meets Fena as she took her around for a grand tour and shows her the blacksmith workshop with machinery that is made with springs, only for Fena to wander off due to her curiosity, much to Karin's annoyance. She meets up with her and Makaba (whom Fena met after Karin), where she takes them to see Shitan, as Karin then leaves the area to allow Shitan to teach Fena archery while Makaba watches. Later, as Kaede and Enju meet Fena whilst meeting Tsubaki and tries to win her affection, Karin suddenly drops from above and steps on top of their heads barefoot, and Karin introducing the twins to Fena by referring to them as Ants #1 and #2, also advising Fena to squash them if they bother her.

She was shortly seen eating kobiru with Fena and the other samurai, as Karin asks about Yukimaru's whereabouts. The next day, the samurai were preparing to leave on their voyage in a submarine that Fena asked if Karin made it, but Karin said that she designed it since her shipwright father constructed it. She shortly becomes annoyed by Salman and Otto since they cannot come with her, Fena and the others on their journey, but is soon surprised when Fena comforted her two relatives.

### Episode 3

She was first seen walking with Fena on their way to meet the others in the submarine ship, which she tells Fena the name of the ship she designed being Bonito II. Karin also lets Fena know that the ship's drive transmission system uses whale baleen and that whale blubber is used as lubricating oil, also noting her fascination that whales are awesome. Meeting with the other samurai, Fena discovers that Karin too has been whacked on the head by Yukimaru, as Karin deduces that Yukimaru has a problem with both of them because of it.

After showing Fena a view of Bar-Baral, she joins Fena and the others (except Yukimaru due to losing a game of Amidakuji) to explore the market as Karin enthusiastically gets excited over valuable items including yakusugi cedar and a rhinoceros horn. Her fun ends shortly as Makaba and Tsubaki take her and Shitan along to get supplies for the ship much to Karin's sadness, while Fena, Kaede and Enju depart from the group to explore the city. When returning to the ship with Tsubaki, Makaba and Shitan later on carrying supplies, they wonder about Fena, Kaede and Enju's disappearance before she sees Yukimaru rush to find the three. After Fena, Kaede and Enju return to the ship, she watches the three get scolded by Tsubaki as the latter hits the three on the head before temporarily tossing them into the sea as punishment.

### Episode 4

She is first seen waking up in the cabin she and Fena are sharing in Bonito-2 after the latter wakes up from a strange dream. She later denied Fena on helping her train with her guns some time earlier, as she begins telling Fena rules on not using a gun as a toy, including precautions and specifications on one of her newly-invented weapons, but then gets upset when Fena leaves the conversation once again to catch up with Shitan. Later on, Karin lends her rifle for Fena to train with as a weapon, but the gunshot blast force sends both of them aback and causing Karin to get a bandage for her nose, before she then scolded Fena.

After arriving at the village of Liber-Oberstein and visiting the Burgomaster with Fena, Yukimaru and Shitan, Karin was then proud of Fena for how right she was when they seemed to get confirmation about the stone being manufactured in the village, until it was corrected to be listed by La Pucelle d'Orleans (Joan of Arc) and purchased in 1436, five years after Joan's death.
