Who's The Real Ninja?!

Climbing into the mouth of Bamora's kaiju suit, Momo confirms Bamora can still sense her, keeping their control synced. On Momo's order, Bamora enlarges the suit and generates Empty Space, stunning Reptilian with its scale, then turns invisible and throws a Blast Wind Thrust Attack. Reptilian evades, aware of the suit's retroreflective projection, and sends up kite ninjas to track its true shape from the air. They rain down a barrage of explosive fireworks with their Ninja Art: Chaotic Sakura.

As the blasts fall, Bamora warns that the suit's energy gauge is draining fast and will deflate at zero. Momo has her close in to catch Reptilian in the blast radius, but he mocks them and dodges everything. Once the gauge empties and the suit shrinks, Reptilian stomps the deflated exosuit and crowns himself the superior ninja.

Reptilian stops short of killing Bamora, realizing her death would forfeit her power, and considers shipping her corpse to the Serpo for dissection. Then Momo's voice asks what he means to harm. Stunned that the girl is alive somewhere, he is mocked by Momo for failing to keep a ninja's speech pattern, and when he tries to correct himself she taunts that it is far too late.

Invoking the tale of Issun-Boshi, the tiny hero who fells a giant from inside, Momo reveals that she and Bamora ejected from the suit, grabbed the ninja explosives, and are now standing within Reptilian's body. As he panics and tries to shake them loose, Momo holds onto Bamora with her power, vows revenge for her grandmother, and fires her Moe Moe Tri-Beam to set off the charges, destroying Reptilian's castle form.

This Volume 24 chapter released on September 9, 2025, sits in the Shimane Arc of the Ultimate Yokai Saga, between Chapter 207 and Chapter 209. It resolves the second round of Momo and Bamora versus Reptilian, leaning on the Issun-Boshi inside-the-giant strategy and showcasing Momo's Moe Moe Tri-Beam as the finishing blow.
