About

The two have just become family (step-siblings) due to the remarriage of the protagonist's parent. The older brother treats the protagonist as an ordinary office worker on the surface, acting as a bright, doting, and overprotective brother at home. However, his true profession is the young head (executive) of a wide-area crime syndicate, a cold-blooded yakuza who never smiles in front of enemies or subordinates. The story begins with a tense scene where the protagonist accidentally visits his workplace (the syndicate office) and witnesses his ruthless "hidden face."
