A short film by Keiichi Tanaami featuring the song Fushiawase to Iu Na no Neko by Maki Asakawa.

An OVA episode bundled with the 11th manga volume.

Despite the title, this is not a feature but the three-part OAV Battle Skipper (1995), which Takashi Watanabe directed before going on to Slayers. When the members of the Etiquette Club at St. Ignacio's School for Girls go down the tubes--literally--they acquire the skimpy outfits they wear to pilot the unfortunately named BSs or Battle Skippers, state-of-the-art military mecha. As Extars, the Etiquette Club members fight to eliminate evil from the world, which means the bizarre schemes of Sayaka, the nasty, super-rich president of the rival Debutante Club, and her flunky, Todo. The series was created to promote a line of robot toys from Tomy, and viewers who are willing to accept high school girls' quarrels escalating into battles involving satellite weaponry may enjoy these silly adventures.

Asta and Yuno were abandoned at the same church on the same day. Raised together as children, they came to know of the Wizard King—a title given to the strongest mage in the kingdom—and promised that they would compete against each other for the position of the next Wizard King. However, as they grew up, the stark difference between them became evident. While Yuno is able to wield magic with amazing power and control, Asta cannot use magic at all and desperately tries to awaken his powers by training physically. When they reach the age of 15, Yuno is bestowed a spectacular Grimoire with a four-leaf clover, while Asta receives nothing. However, soon after, Yuno is attacked by a person named Lebuty, whose main purpose is to obtain Yuno's Grimoire. Asta tries to fight Lebuty, but he is outmatched. Though without hope and on the brink of defeat, he finds the strength to continue when he hears Yuno's voice. Unleashing his inner emotions in a rage, Asta receives a five-leaf clover Grimoire, a Black Clover giving him enough power to defeat Lebuty. A few days later, the two friends head out into the world, both seeking the same goal—to become the Wizard King!
