Waru

Meet Tanaka Maririn, just graduated from college and beginning her life in the workforce… at the bottommost rung. She’s not expected to know much (and she doesn’t) and she’s not expected to last long, but few at first are aware that not only does she have an upbeat attitude, but a sarcastic streak a mile long and a fearlessness to match with it. Sometimes she wears slacks instead of a skirt. She WILL succeed, and she WILL find that handsome man she saw only briefly on her first day of work after her orientation.

Don’t even think you can stop her…

Won the 15th Kodansha Manga Award for general manga in 1991 (tied with Kachou Shima Kousaku).
