The problem with the human Shinju.
Hi! I’m a huge Boruto fan, but right now I have a concern—or at least a fear—regarding the human Shinju.
They’re introduced as a major threat, and each one has its own target. Their whole narrative and development revolve around the idea of devouring that target. This has been teased constantly since their introduction in the early chapters of Two Blue Vortex… but so far, not a single human Shinju has actually succeeded.
For the past few arcs, the pattern feels repetitive: the villain never reaches their goal. Ryu failed, Matsuri failed, and I really thought Mamushi would succeed in devouring Eida—but that didn’t happen. Sure, Inojin got some spotlight, which is nice, but the fact that Mamushi failed to devour a character like Eida—who barely had any narrative importance left—feels like wasted potential. It also shows that Ikemoto wasn’t willing to kill off an important character.
There needs to be real tragedy. Even if Inojin losing his eyes is impactful, it’s still not enough. From a storytelling perspective, that moment felt like the last real opportunity to show a Shinju successfully devouring its target. And honestly, it feels obvious now: if Ikemoto didn’t go through with killing Eida or Konohamaru, then Hidari will never devour Sarada. She’s a main heroine—he’s not going to kill her. Jura probably won’t devour Naruto either, because that would mean killing Naruto, which Ikemoto likely has no intention of doing.
In the end, it almost feels certain that none of the remaining Shinju will ever succeed, meaning we may never actually see one accomplish its goal—and from a writing standpoint, that’s a problem. For example, Obito actually achieved his objective by becoming the Ten-Tails’ host. Here, none of the Shinju are achieving anything, even though it’s essential for their development.
I also don’t think Jura will devour Himawari, because that would make him way too overpowered. He’s already extremely strong, and absorbing Kurama’s power would push him even further. And realistically, I don’t think Ikemoto would kill Himawari like that either.
So yeah, I’m curious what you all think, but to me it feels like Ikemoto is mishandling the Shinju storyline. That said, I’m not saying everything about them is bad—they’re actually one of the best additions to the story. But their development needs to fully pay off, otherwise it loses its impact.
