In year xxxx, on the continent of Lanster, humans were divided into levels from D to SSS, as well as mediocrity.
Some people are born to be proud of heaven, and some people are born to be mediocre.
But, don't worry!

And if you choose this path, you will face full military management. If you are eager for quick success and want to quickly improve your level, injury or even death is inevitable.
If you upgrade quickly or perform well, then you can join a team called "Blooded Blade" directly led by S to SSS levels. If you can be selected, it will be the glory of your ancestors, but at the same time, you will also have to face more cruel challenges...

It's not as glamorous as it seems...
Of course, you can also choose to live a mediocre life...
