Kadoki, who was born in the Tomato Orphanage, was sent to the Ninja World by a dump truck.

I have a dad who is calm and reliable, and sometimes likes to do some "little operations".

I have a mother who is gentle, considerate, opinionated, and sometimes a little bit scheming.

There is a younger brother who is lively and naughty and adores his older brother.

Although there is still a mortgage to pay, it is still a happy and warm home.

But, his brother's name is Umino Iruka.

My name is Umino Kadoki.

Saving his family from the future Nine-Tails Rebellion is the first thing Umino Kadoki has to do when he enters the ninja world.

Relying on a system plug-in that can copy ninjutsu and even bloodline limits, Kadoki is working hard to become stronger.

Finally one day, Umino Kadoki became the strongest ninja in the world.

Only then did he understand the meaning of "the greater the ability, the greater the responsibility".

"I will unify this ninja world and break the endless chain of hatred!"
