A Day With Rinko-chan

"That spring, an eleven year old girl bought a man for the first time."

After her mom left, leaving her five hundred thousand yen, Rinko sets out into the city at night to find her, but instead meets Haruno, found passed out at the intersection. Haruno introduces himself as a kept man, and Rinko, who can no longer bear being alone, decides to hire him.

The distorted and painful life of an elementary student and a kept man, somehow still full of warmth, is about to start.
