Ch. 661What, You Thought I Was Doing It for Nothing?
Key events
- Minato and Kakashi exploit the Flying Thunder God mark on Isshiki to send him into Kamui Space.
- Obito plans to release Isshiki later, but Kushina attacks him with a Tailed Beast Bomb, interrupting his Kamui.
- Obito chooses to endure the blast to demonstrate his Six Paths strength, but is burned—evidence that Kushina’s attack can harm him.
- Naruto realizes she must have used Natural Energy. Kushina reveals she never learned Sage Mode: years of encounters with Shirozumi, whose body absorbs only Natural Energy, allowed her to accumulate it and infuse it into her attacks.
- Obito evades Kushina’s follow-up bombs by using Kamui’s Hollowfication. But because Hollowfication transfers his body into Kamui Space, he risks appearing beside the sealed Isshiki.
- Kushina’s actions are revealed as deliberate: she knows Obito’s claims about the Ōtsutsuki may have consequences under the world’s supposed “Heaven’s Will.” The chapter ends by wondering whether the creator of this world could make Obito’s fabricated story become true.
Character developments and interactions
- Kushina is revealed as strategic as well as powerful. Her relationship with Shirozumi provided both Natural Energy and information about Heaven’s Will.
- Obito remains confident and eager to show off, but is caught off guard when Kushina injures him. His own lie about the Ōtsutsuki may now threaten him.
- Naruto recognizes the Sage-energy explanation but is astonished by how Kushina acquired it.
- Minato and Kakashi work together efficiently to trap Isshiki in Kamui Space.
- Kushina explains her secret to Naruto, while Obito hears it from above; Naruto’s cheering briefly makes Obito think the attack is simply a distraction.
Significant themes
- Deception and consequences: Obito’s invented explanation of the Ōtsutsuki may become dangerous if the world’s unseen forces reshape reality around it.
- Preparation and hidden motives: Kushina’s apparent indulgence with Shirozumi also served a practical purpose.
- Cause and effect under Heaven’s Will: The chapter raises the possibility that belief, observation, or narrative itself can alter what happens.
