Born into the Sakimori family, a lineage of rope masters, Souichi is the son of a renowned kinbaku artist.
After the death of his father, Gentarou, Souichi begins a new life with his mother, Yoshie—just the two of them now.

Trying to be considerate of his mother, who’s been left alone, Souichi reflects on his relationship with his late father as they adjust to their new reality.
One night, Souichi hears a faint noise in the distance and follows it.
What he finds is something he shouldn’t have seen—his mother, Yoshie, in a compromising position.

Caught between his love for his mother and his own desires, Souichi is torn.
Glimpses of Yoshie’s inner turmoil come to light…
What does it mean to be a rope master?
What does it mean to be a mother?

This is a short, immoral tale of a mother and son in the Sakimori household—a story of tangled emotions and forbidden desires.
