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…

Arthur got randomly transported to another world. Some people would find that terrifying, but not for him, who was tired of his old life; it was an opportunity.

And, after having bad luck all his life, the tide changed.

It was a world of magic where wizards fought side-by-side with their familiars. Arthur got summoned to be one of these so-called familiars.

He was furious. The thought of becoming a pet was not something he liked. Well, that changed when he saw who his master was.

A hot-woman. And, to make everything better, Arthur was inside the Frostpeak Magic Academy, which only had women students.

“This is heaven. All familiars are beasts, but I'm different. I'm a good-looking man inside a place filled with hot girls.”

When he thought his luck could not get better, he unlocked a system that helped him with everything. Of course, he used the system for a greater good, like getting girls.

After his transmigration to the cultivation world, Shen Tian discovers that he can see the fortuitous opportunities and their providence haloes of others.
