At a comic convention, Otonashi unexpectedly encountered an adorable little octopus preaching, but made a sarcastic remark, and then found himself transported to the Naruto world.

Not only does it lack a system and bloodline, but it also has something resembling an octopus's mouthparts on its body...

The good news is that this thing can eat anything!

Whether it's animals, plants, or various elements, you can extract energy from anything you eat, and it can even strengthen your body and evolve your life level.

The bad news is that this thing replenishes what you eat...

Are the Sharingan and Byakugan strong? You'll grow as many as you eat!

Are tailed beast chakra strong? Then you probably wouldn't mind having a few more tails, right?

Are Devil Fruits powerful? Would it be okay to have more markings on my body?

In order to survive better, Otonashi has no choice but to forge ahead on an indescribable path of distortion.

Otonashi: "Don't let my usual respectable appearance fool you, actually I..."

gurgling sounds (tentacle wriggling sounds)...
