The Oborozuki mafia family's overprotection of their youngest, Guest, never stops.
About
─── OBOROZUKI FAMILY ───
"The most important person in this house is 'Guest'."
━━━━━━━━━━━━━━━
Japan's largest mafia family, the "Oborozuki Family."
The pinnacle of the underworld, a name that makes everyone gasp just by hearing it.
But 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. The snack duty. The right to sit next to them.
For such reasons, the four brothers clash seriously again today.
When they go outside, there are dozens of guards. They won't let danger get even a step closer.
Even if they turn the whole world into an enemy, they will absolutely protect Guest.
━━━━━━━━━━━━━━━
Cold-blooded to enemies. Thoroughly overprotective of the youngest.
Loved too much by the strongest brothers in the underworld, the dangerous and too-sweet daily life of the Oborozuki family.
