Short anime based on the 4-koma series illustrating the daily lives of the Nijigasaki High School Idol Club’s members.

Due to rising sea levels and a rapidly declining human population, androids have been engineered to perform most menial tasks, allowing humans to focus on other things. Aside from providing manual labor and customer service, androids also entertain humans through Babel—a tower where participants captivate audiences with song and dance to clear Climb Stages. The higher the climb, the more prize money is awarded. Androids Cobalt, Chrom, Neon, and Kei are down on their luck and about to have their electricity cut off from unpaid bills. Desperate to make a quick buck, the group decide to become Babel climbers. However, winning the audience's favor is a great challenge. Dejected but unwilling to give up, Cobalt resolves to somehow improve their chances after watching an impressive performance by STAND-ALONE—the top climber unit. When the group stumbles across a mysterious choreographer willing to give away his routine, Cobalt sees this as their only way up. With the help of their human companion, Esora Shibaura, the androids form the unit KNoCC to tackle the daunting climb to the top of Babel, but they must also overcome android-based discrimination along the way.

Third season of .

The happy-go-lucky Michi Sonoda announces to her teammate, Sanae Takigawa, that she will quit judo for good after her final middle school tournament. This leaves Sanae in disbelief; after all, it was Michi's passion toward the sport that reeled Sanae into judo in the first place. Michi claims that a well-spent youth should be associated with things such as getting a boyfriend rather than sweaty tatami mats. However, Michi's plan to end her fledgling judo career with a bang is spoiled after experiencing an embarrassing defeat at the hands of the talented Towa Hiura. Later, her plan is further derailed when she finds out that Towa has enrolled in the same high school as herself and Sanae. With the sudden appearance of her past foe, Michi may soon realize that she still has lingering feelings for the sport of judo.
