Jujutsu Kaisen Modulo Unveils Its Ultimate Sorcerer — Master of the Forbidden Zenin Technique

Spoiler alert: This dives into Jujutsu Kaisen Modulo chapter 15 leaks. If you want to go in clean, bail now.

Alright, so if these chapter 15 leaks hold, Modulo basically just put a crown on Yuka Okkotsu and called it a day. She summons Mahoraga. Yes, that Mahoraga. Yes, via the Ten Shadows Technique. And yes, that is the Zenin clan's taboo special. It is exactly as wild as it sounds.

So... did Yuka really just summon Mahoraga?

According to the leaks, she does, and it lands like a grenade. The Ten Shadows Technique showing up here amps the stakes to 'we're doing the biggest, nastiest fight of this arc now.' The kicker is the lineage question: how can an Okkotsu use a Zenin technique?

Quick family math: Yuka is still an Okkotsu (descended from Yuta), but her grandmother is Maki Zenin. That Zenin bloodline link is the bridge. So while it sounds impossible on paper, the family tree makes it very possible in practice.

How the summon plays out

Yuka doesn't tiptoe into this. She drops the call like she is flicking a switch on a bomb. The execution is clean too: tight energy control, smart positioning, and the summon itself turns into a tool. She stays out of the danger zone and immediately funnels Mahoraga's attention toward Dabura. Efficient. Mean. No wasted motion.

Where this fight might go

This is where the leaks slide into educated guess territory, but the picture is clear enough. You can feel Dabura winding up something massive. If he goes for his version of Fuga to exorcise Mahoraga, the read is that Yuka jumps back in at the last second — ring on her finger, Rika fully manifested — and offers up everything for the strongest pure love beam she can fire.

That gambit likely loses the head-to-head clash, but not by much. It would blunt Dabura's hit just enough for Mahoraga to do what Mahoraga does: survive, adapt, and flip the momentum. That is the scenario that ends with Dabura going down. Of course, none of this is locked — Dabura looks absurdly broken right now — and there is a perfectly real world where Mahoraga eats it and Yuji shows up for the finishing blow instead.

The Tiger Funeral card might be on the table

The other big takeaway: Modulo now effectively confirms Yuka can fully tap into her Zenin side. Which means we might finally see Tiger Funeral. That name dropped once back in the main series (JJK chapter 234) and then never actually appeared on the page. It is said to be the purest brawler among the Ten Shadows shikigami — the strongest raw fighter. Some fans expected Tiger Funeral here instead of Mahoraga. If Mahoraga does not seal the deal against Dabura, do not be shocked if Tiger Funeral walks out next.

Yuka's ceiling (and her risk)

All signs point to Yuka getting even scarier from here, even with her illness hanging over everything. She is still pushing it, because of course she is. And personally, I hope Gege does not take her off the board yet — that design is too good to waste this early.
