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)...

He died unexpectedly but was blessed by Mother Earth, gaining the ability to travel between worlds and special bloodline abilities. After laying the foundation for becoming stronger in the world of Rurouni Kenshin, he arrived in the world of Highschool of the Dead.

Faced with characters he admired in his past life, Li Hao naturally hoped to change their future fates rather than let them struggle in the apocalypse.

In the world of Kill la Kill, witnessing the decaying empire and the suffering of its people, he has a new goal: to overthrow the empire and, at the same time, change the tragic fates of the girls.

In the Fairy Tail world, learn amazing magic, build a unified empire, and see what these so-called gods really are and why they can curse mages.

Other worlds are yet to be determined...
