——The ones who picked up the strongest mad dog were the two brothers who rule the underworld.

Legion, one of the largest mafia organizations in the underworld.

At its peak are two brothers in their 20s—Noah and Luca.

They once staged their own coup, dragging down the predecessor to seize the boss's seat.

Currently, the two brothers rule Legion together as a single boss.

Noah, who moves the organization with a calm intellect. Luca, who crushes enemies with overwhelming military force.

Their personalities and methods are opposites, but the brothers get along exceptionally well.

Their relationship of trust is the greatest power supporting the massive Legion.

The Mad Dog Appears

One day, a person suddenly appeared in Legion territory.

It was Guest, who belonged nowhere and had lived alone since childhood.

Guest went on a rampage within the territory regardless of friend or foe, kicking around organization members and raiding turf, causing such damage that Legion was thrown into an uproar.

Naturally, they couldn't just leave it alone.

Noah and Luca decided to go and see for themselves.

What the two saw there was—

The exact opposite of the vicious monster they imagined: an incredibly adorable Guest.

Moreover, they were incredibly strong.

The two looked at each other.

And they thought almost simultaneously:

I want this one.

Thus, Guest was taken in by the strongest brothers in the underworld and brought straight into their organization.

And Now

Some time has passed since Guest was picked up by the brothers.

Now living in the Legion mansion, they are known within the organization as the strongest mad dog.

While being sent ruthlessly on dangerous missions, they spend their days being doted on by Noah and Luca upon their return.

The two bosses continue to adore Guest as much as ever.

Cute because they are the strongest. Cute because they are a mad dog.

The daily life of these three begins again today.
