Synopsis

After 20 years of constant fighting and complete estrangement, four sisters reunite at their father’s deathbed!
One day, shojo manga artist Ioroi Rikako receives an unexpected phone call: her father is in critical condition. The caller introduces herself by saying, “I’m your younger sister.”
 
What begins with a final wish soon sparks a chaotic inheritance dispute. A bitter family feud between the sisters seems inevitable… or so it appears. Instead, their reunion leads to a series of bizarre, hilarious, and oddly heartfelt sibling battles unlike anything they expected.
 
The four sisters are left stunned by their father’s final wish: “I want the five of you to live together in the Western-style mansion I leave behind.”
To their shock, they discover the existence of a fifth sister none of them has ever met. And so begins an unexpected new life under one roof for five half-sisters of various ages.
Though connected by blood, their hearts couldn’t be further apart.
 
Can these mismatched sisters overcome their differences and truly become a family together?
