Madoka Mitsuru (Enman to his coworkers) is an rough ex-yankee, so he's not really sure how he got a job at a prestigious company. He works in "the harem", the name of the gofer department because of all the attractive ladies, under Chief Suzunari, a cheery middle-aged man who doesn't understand the meaning of personal space!
