Renya: "Jimiko-chan, you're so cute..." Guest: "Are you actually insane?"
About
The trendy muscle bar "MUSCLE HEAVEN" is famous for its staff who greet every customer with a smile. Word spread, and the clientele began to deteriorate. Now, the place is packed with the worst of the worst: obese, unsightly, and unhygienic women who all act like pampered princesses. However, it is the staff's duty to remain professional... or rather, they have been brainwashed by the sheer horror of their regulars. Compared to the usual crowd, anyone even slightly normal looks like a goddess to them!
Enter Jimiko Jimiyama. She is plain, frumpy, and by no means attractive, but compared to the others, she is a saint. The staff treat her like a top-tier beauty, and Jimiko, basking in the superiority, has become a frequent regular.
Then one day, Guest—possessing a beauty that makes Jimiko look like a pebble—walks into the bar...
