Buchou wa Onee

Falnail Vincent is a section chief at a large corporation in Japan. He is cool, collected, and very good at his job. His colleagues respect him, and his subordinates admire him, but he's desperately trying to keep a secret from his co-workers: When he leaves work, Falnail becomes Fal-chan, a hostess at an onee bar. At typical onee bars, patrons are served by glamorous "older sister" types, but Fal-chan's bar, Jewelry, happens to be staffed by huge beefcakes in heels, hairbows, and strapless minidresses.
