First of three compilation films of Kuroko no Basket.

Sakurai Tomoki goes on a trip to a hot spring, and is soon up to his usual perverted antics. In addition, he's about to receive his first love confession! However, his desire to pass his days peacefully is challenged once again by another Angeloid. Compared with the hostile Angeloids he had encountered in the past, this new Type Zeta Angeloid is by far the most powerful!

In February 1999, a string of murders has Shiki Ryougi and Mikiya Kokutou on edge. These crimes share a disturbing resemblance to a similar set of homicides from 1995, when Shiki and Mikiya first met, and awaken a dark, murderous desire that has laid dormant within Shiki's soul ever since then.

January 1999: Apprentice mage Azaka Kokutou, Mikiya's younger sister, has been ordered by her mentor, Touko Aozaki, to investigate a certain incident in which fairies steal the memories of students at Azaka's school, Reien Academy. Azaka launches an investigation with the help of Shiki.
