Whoa, I was genuinely surprised by how much I ended up liking this Guren and Yukimaru filler arc; it just flowed so much better than most side stories. But Naruto’s arm getting absolutely annihilated by his own Rasenshuriken? My stomach dropped watching that, and it's crystal clear why Tsunade would forbid such a dangerous jutsu—he nearly took himself out! I'm holding out hope that Jiraiya finds a way for him to safely harness that power, because my boy needs to survive to become Hokage, not self-destruct.
