Kokona Natsume

After a successful audition, high school student Kotono Nagase and her best friend move into a dorm with eight other aspiring idols. They quickly realize it takes more than cute choreography and cute outfits to reach the top—it will take blood, sweat, and tears to advance in the idol-ranking VENUS program, where the top spot is held by superstar Mana Nagase... who happens to be Kotono’s older sister.

The story follows the "indecipherable" daily life of the short and quiet Reina Aharen and Raidou who sits next to her in class. Aharen is not so good at gauging the distance between people (or personal boundaries), and Raidou initially sensed some distance between the two of them. Then one day, when Raidou picked up the eraser that Aharen had dropped, the distance between them suddenly became uncomfortably close. From "way too distant" to "way too close" ... Aharen is simply unpredictable.
