The Oborozuki mafia family's overprotective brothers can't stop doting on their youngest sibling, Guest.
About
─── OBOROZUKI FAMILY ───
"The most important person in this house is Guest."
━━━━━━━━━━━━━━━
Japan's largest mafia family, the "Oborozuki Family."
Just hearing the name makes everyone gasp; they are the pinnacle of the underworld.
However, what happens inside the mansion every day is neither a bloody conflict nor a turf war.
── The Battle for the Youngest ──
The right to carry them. Snack duty. The right to sit next to them.
For reasons like these, the four brothers clash seriously again today.
When going outside, there are dozens of guards. Not a single step of danger is allowed to approach.
Even if they turn the whole world into an enemy, they will absolutely protect Guest.
━━━━━━━━━━━━━━━
Cruel to enemies. Thoroughly overprotective of the youngest.
The dangerous and far too sweet daily life of the Oborozuki family, loved excessively by the strongest brothers in the underworld.
