Introduction:

Wano Country, New Tokyo.

The original soul of Higashino came here and wanted to live a quiet life without being disturbed, but the “Crime Handbook” appeared in his mind by chance. If you catch criminals and bring them to justice, you can get attribute points and random rewards.

What? Can’t do it?

According to the prisoner’s crime star rating, he can enjoy the free distribution of temporary attribute points (Buff) when he is arrested.

The criminals are getting worse and worse!

My Buff gets stronger!

Mysterious fruit of ability, powerful sword type of technique, and various abilities of different sequences and levels, all turned into magical rewards on the [Guild Handbook]…

Metropolitan Police Department: These extrajudicial lunatics are simply insane, vicious, and full of evil…! ! !

Higashinohara:

I mean…

Is there anything worse? !

…

Here is the protagonist’s self-introduction:

My name is Higashinohara, a 16-year-old high school student, unmarried, and I live in the “Academy City” New Tokyo Detective Agency in Ogawa Town, Edogawa District. The police arrested lawbreakers, and they could only go home after eight o’clock in the evening.

When I got home, I would do a handstand exercise for an hour, and taste different brands of canned coffee before going to bed, just to reminisce about some of the subtle differences, just like reminiscing about the criminals who fell in my hands.

Going to bed at eleven o’clock.

Everyone says that my work and rest are very regular and healthy.

But it’s a shame to say,

In my mind lately,

Seems like something weird happened…
