He ended up passing away when she was four. Recently Kathleen have becoming deprased for all the people they lost, but with Sensui and the rest, she feels they can get through it.

Dr. Yoshinaga is about to get attacked by Gibia turned Brian, however Adam comes and manages to kill him. Hearing the Gibia telling his name, Adam realizes this was Brian. Yoshinaga explains he got infected when the Meteora injured him.

While the group explores around, they lose sight of Yurika and start looking for her. Sensui finds her and she points out there is samurai exhibition. As they explore, Sensui, Kenroku and Yukinojyo can't believe their eye as they find their old weapons. Sensui finds his katana Suigetsumaru and his western sword Halbert. As they gear up, they end up being attacked by Gibia and going outside, they see it started to rain, and the clouds covered the sun and made it darker, so the Gibia came out. While they fight the Gibia, Yoshinaga and Adam arrive with a camper and help them out.

Seeing Sensui serious, Kenroku is reminded of their past and how he met Sensui. Sensui is forced to return from the war in Korea and Kenroku sees him on the streets, realizing he is dual-wielder. Jouzen Matsumoto, like other vassals, had to make a decision to support the Eastern or the Western army. He make promises to both side, but in the end takes the Eastern army side and Sensui marches into war against the Western army. Kenroku observes the battle and sees Sensui. As the battle ends, and Sensui returns, he intercepts them and wants to fight him. Facing him, Sensui cuts Kenroku's kusarigana chain, but Kenroku manages to dodge Sensui's slashes. He attempts to attack with his claws, but Sensui blocks. Kenroku then retreats stating that if they continue, neither will remain intact and they will revisit their fight some other time.

Their camper punctures a tire and they are forced to stop. The sound of punctured tire draws Gibia. As Sensui is exhausted from the previous battle and still resting up, Kenroku and Yukinojyo come out to fight the Gibia, but are surprised by the amount of lizard Gibia approaching them.
