The youngest daughter who worries about completely pointless things. The super indecissive middle daughter. The extremely annoying, lip smacking eldest daughter. Starting with these three sisters, this is a story about loveable, clumsy people. A short slice of life comedy that surprisingly has nothing to do with the universe!!

One day out of boredom, Tanaka decided to give her classmates nicknames based on their quirks. Her friend Sakuchi became “Ota” for her nerdy interests, and her other friend Saginomiya became “Robo” because of her expressionless personality. In retaliation, her friends decided to name Tanaka “Baka”. These are the ridiculous days of three high school friends claiming (or not) the height of their youth.
