Project A-Ko Versus Battle 1: Grey Side

To preserve the peaceful times of Paradise, the Astrostar must be cleansed by the Mamamega. This person is defended by her shrine maidens. Lilith has been selected to be a shrine maiden, and is given the task to select the other two. This goes awry when the young girl Rurubell wants to become one and others work from the shadows to sabotage both the cleansing and the coronation ceremony.

Earth. The not too distant future. A city is miraculously reborn just sixteen years after being completely destroyed by a giant meteor. At the prestigious Graviton High School for Girls, two new students are introduced. A-ko and her ditzy sidekick, C-ko.

Aika is an intelligent and athletic high school girl. Competently she successfully passes the salvager's licence test, obtaining a C-class license. Yet, she is young and hot-headed, so much so that Gozo still treats her like a child. Due to this personality, no one is willing to hire her for salvaging jobs. Eager to get started with salvaging, though, she decides to post an ad in her school to attract potential clients. She manages to get the attention of Eri, a daughter of a rich family and head of the school's treasure hunting club. She asks Aika to salvage something from the sea floor and Aika accepts the assignment. However, upon seeing the state-of-the-art submarine loaded onto Eri's private cruiser and discovering their destination, Aika realises the dangerous nature of this mission, culminating in a clash with a group of armed high school girls on the southern islands.

Aika Sumeragi works as a salvager for hire, but gets caught up in a plot for world domination.

Villgust is a peaceful world that exists parallel to ours. However, now an evil deity has been revived and has sent evil creatures to destroy many countries, which left darkness and terror to rule the world. The peoples' prayers and cries has reached out to the goddess Windina and in order to free the world from darkness she chose eight brave warriors to defeat the evil deity. Although blessed, these warriors are unaware at the path chosen for them, thus the two groups of Kui, Chris, Fanna, and Youta must meet up with Murobo, Remi, Ryuquir, and Bostov before they can follow the path chosen for them and defeat the evil deity.

In the future, five female high school students form Sailor Victory to command three giant ninja robots: Gion, Momoyama and Sagano, so that they can fight against evil in the virtual-future of Mikado City. In these two episodes, a disgraced and disgruntled city employee aims to humiliate the Sailor Victory crew by joining up with the evil Margarita. Little does he know that she is bent on destroying the city...

It will take a lot of strength to slay a three-headed dragon, perhaps more than A-ko, B-ko and Maruten can muster. As these intrepid souls invade a space station ruled by their nemesis, they encounter star pirates, hidden explosives, seductive spirits, and female warriors with no discernible loyalties. And, of course, that fire-breathing beast with football field-size wings and a trio of mouths -- each brandishing saber-length teeth!
