【Kiruao】The latest work by the author of “Kuroko's Basketball (Kuroko no Basket)” and “Robot x Laserbeam” is an school action manga about a single assassin who has to start his life over!

Legendary assassin Ogami Juzou accepts a mission to destroy an evil organization.

He quickly destroyed that organization, as he is considered a legend and quite powerful.

After finishing work, Juzou returned home. There he bumped into a child as he exited the elevator, and the child ran away crying. He then reflected on his life up to now.

I was married and had children, but divorced.
The children were big enough, but I wasn't good at them and didn't know how to talk to them.
We had nothing in common. I have no hobbies......I only had my job, but I was good at it and didn't really like it. It's a boring life......

And when he woke up, his body had shrunk and he was back to his thirteen-year-old self!

To Juzou's confusion, Eri Wanibuchi, his ex-wife and a researcher for Z.O.O., the hit squad to which Juzou belongs, explained in a matter-of-fact manner.

The bee that stung Juso was an organism developed by a business partner of his target organization. That company was researching genetic engineering of organisms. A new species of bee had been genetically engineered and its venom had not yet been analyzed.

It did not seem likely that he would die immediately, but he would have to take time off work.

Juzou, who has a mortgage on his house and car, is in a panic, but then he receives a phone call.

It was a job offer from Z.O.O.'s boss.
He wanted Jouzou to go undercover at the middle school where his daughter will be enrolled next year and find out what kind of school it is.
Jouzou rebels against the boss, but the boss says he will pay him.

Juzou was torn between earning zero income and going undercover at a middle school, but in the end he decided to go undercover at a middle school as a seventh grader.

Juzou was given an intercom and a pair of high-performance glasses with a camera by his partner, Nekota Kotatsu. He was to live as a middle school student.
Having been picked up by Z.O.O. at an early age and discovered as a talented assassin, Juzou, who had only attended elementary school, will now live here for the first time as a middle school student.

Juzou has been alive for decades now, so learning has become instantly more interesting. Relationships with children he used to have difficulty with and little incidents in his daily life hit Juzou! Will he ever be able to return to his former self?
