Mahou Kabushikigaisha

Kanako likes magic, and her dream to work in the country's largest Magic Company is fulfilled. However, the department she is in has almost nothing to do with the main branch because the Second Research class consists of no one but a bunch of slackers. In order to make their name sound, Kanaka tried her best to encourage her teammates to produce new magic items and to help them while improving her own magic skills. Wikipedia
