Sequel to Diamond no Ace: Act II.

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.

Second season of Hanazakari no Kimitachi e.

Ever since she was a child, Himari Aozora has adored the world of the idol princesses known as AiPri. Long ago, Himari made a promise with her best friend, Mitsuki Hoshikawa, that they would debut as AiPris together. However, Himari has grown to be incredibly shy, and she has all but given up on her dream. Both girls enroll as first years at Paradise Private Academy. On the first day of school, Himari gets lost on her way back to the dormitory and stumbles upon a room radiating a pink light. She falls into the room, and a bracelet clasps onto her wrist, transporting her to the AiPriVerse—the world where AiPris perform. Himari accidentally enters the newcomer auditions for the AiPriVerse, and her performance impresses Paradise Academy's Student Council. They offer to become her producers, with the condition that she will conceal her status as an AiPri. Little does Himari know that Mitsuki herself is also an AiPri and has been hiding it from her! Their childhood dream of performing together gradually comes to fruition—even as the academy's principal threatens to ban AiPri from school grounds entirely.
