Rurouni Kenshin, Vol. 9 continues where the previous tankōbon left off and contains the next nine chapters (67–75) of the on-going manga series.
Saitō Hajime catches up with Himura Kenshin and after learning Shishio Makoto is in the village, they go to confront him. After meeting Shishio, Kenshin is attacked by Shishio's soldier, Senkaku. Kenshin easily defeats Senkaku, but Shishio departs for Kyoto leaving Ōkubo Toshimichi's murderer, Seta Sōjirō, to fight Kenshin. The fight ends in a tie with both of their swords broken and the village is freed.
Kenshin and Makimachi Misao arrive at Kyoto and meet Misao's guardian, Oniwabanshū Okina. Okina helps Kenshin find Seikū Arai, son of the creator of Kenshin's sakabatō sword, Shakkū Arai. Kenshin wants him to make another reverse-blade sword, but he refuses because he hates violence.
Meanwhile, while traveling to Kyoto, Sagara Sanosuke meets a fallen monk, Yūkyūzan Anji, who teaches him the Futae no Kiwami, a powerful technique that can pulverize rock. Sanosuke never learns that Anji is a soldier from Shishio, but after he leaves Seta Sōjirō turns up to get Anji.
This tankōbon is written and illustrated by Nobuhiro Watsuki. The Kyoto arc continues as Himura Kenshin chases the elusive Shishio Makoto who murdered Ōkubo Toshimichi and managed to break his reverse sword in a battle with Seta Sōjirō. Also en route is Sagara Sanosuke, who meets up with Yūkyūzan along the way and learns a new technique.
All in all, Rurouni Kenshin, Vol. 9 is a wonderful continuation to a series that seems really intriguing and I can't wait to read more.
