The water from Musashino was given to Kaoru and once she showed signs of recovery, Kenshin and Jinpu set out immediately to Nikko to find the Water clan. Meanwhile, Tsunan and Sano were asked to find out where Ryuu Myaku would be diverted, where it would headed and when it would strike. Sano and Tsunan found out from one of Saeki’s employee that Saeki had asked him to find a book on the separation of religion and politics seven years ago.
They visited the author of the book, Horinaka Tadashi, who told them about Senjo Gahara, where a holy object that controlled natural forces were kept. He also told them about Youmei Mon, where the Hisui crest were kept. The Water clan destroyed another bulding, this time it was State Defense Department building. Just a moment after it was destroyed, several members of the Daijokan arrived and arrested Yamagata-kyo for using the Konoe division and seizing a civilian property without the Daijokan’s permission. Kenshin and Jinpu had arrived at Youmei Mon. Reisui found out they were there and attacked them by using a formation he had prepared before. During this attack, Kenshin met his decomposing-self and had to come to terms with himself to break away from the formation.
Sano came, riding a horse, telling them what he had found out. Kenshin, Sano and Jinpu set out towards Sanju Gahara to confront the Water clan. Tsunan and Kawaji were working together to figure out what they could do. Tsunan concluded that they should be able to stop it if the formation at Kan-ei tmeple still existed. That temple were burned down 11 years ago. At this time, Horinaka Tadashi appeared and told them that he wanted to help them.
