Arc 20The Gods of Takamagahara
Shinsei and Kaguya uncovered Takamagahara’s human sacrifices and confronted the gods over the God Tree, while Shinsei gained control of Kagutsuchi’s flames. Madara joined the battle and killed Susanoo, as Omoikane revealed his plans for the gods and led Kukurihime to Amenominaka.
- Shinsei disrupted Ninigi-no-Mikoto’s altar ritual, but the rescued pair returned and were killed when they offered themselves for sacrifice.
- Kukurihime-no-Kami showed Ninigi-no-Mikoto a vision of Kaguya destroying Takamagahara and explained that Shinsei and another hidden force had obscured the future.
- Shinsei killed the false flame sage and defeated Kagutsuchi-no-Mikoto, absorbing his fire ability as Kaguya remembered her sister and told Shinsei she no longer wanted to be an Ōtsutsuki.
- Shinsei and Kaguya reached the God Tree, where Takemikazuchi-no-Kami and Susanoo confronted them, and Shinsei refused to abandon Kaguya.
- Shinsei fought Takemikazuchi-no-Kami and Susanoo until Madara arrived, declared he would protect the God Tree, and proposed that he and Shinsei kill the gods together.
- Madara used True Several Thousand Hands to destroy Susanoo’s giant and kill him, while Shinsei sealed the Kusanagi Sword and Takemikazuchi-no-Kami fled toward Takamagahara’s blocked gate.
- Omoikane-no-Kami told Kukurihime-no-Kami that Mikata Raijin was also meant to die, then showed her the rift Yomi-tsu and identified an immense head in black rock as Amenominaka.
