Hundreds of years ago, Human, Celestial Clan and Demon Clan lived together on the Origin Continent. However, a great war broke out between the three races. Shan He, the leader of Human, had discovered a catalogue of methods to forge Divine Weapons. With this catalogue, Shan He led Human to defeat the other two clans and expelled them from the Origin Continent.

The peace did not last long. After the passing of Shan He, the once Glory Empire collapsed. Various forces of Human fell into a long period of wild war for the Divine Weapon Catalogue, but the catalogue was lost during the war.

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…
