Reincarnation 29 (Flowers)

Reincarnation 29: Death Zero 11 (亡零 (11)) is the 29th and final chapter of the Shaman King Flowers manga.

Short Summary
Horrified by Sakutaro Sakurai's ruthlessness, Asakura Hana forces the plane to turn before Sakurai can kill Kamogawa Yohsuke aboard the carrier. In response, Sakurai shoots Hana, killing him. Yohsuke realizes that Asakura Hao chose Sakurai to become Hana's new Guardian Ghost because Sakurai was the first person to be cruel to Hana.

Hana awakens in another part of Hell where Sakurai's dead allies reside. They similarly believe that Sakurai's zeal for war is to eliminate the society that encouraged him to go to war without question before killing himself. As Hana reflects on what his own reasons to fight are, he suggests that Sakurai's motivation is actually love, the one thing he lacks.
