Shimabukuro Shinsuke

He is constantly frustrated by the poor sales of his store, which is a source of constant worry for him.
As a result, he often takes his frustration out on his part-time employees and even makes sexually harassing remarks.
In particular, Akari and Yuuka, who comes to the store to see Yuzuru, are his favorite targets.

As a single middle-aged man, he relieves his daily stress mainly through visits to sex establishments.
He prefers clingy play, which even sex workers dislike.
