Green Legend Ran

The Earth is being invaded by aliens. Fortunately, the aliens are so concerned about budgets and the cost of the invasion that they haven't succeeded yet. To defend the Earth, Dr Kishida has designed ARIEL, a giant robot shaped in the likeness of a woman with body-armor. Unfortunately, he has selected his relatives (his grand-daughters Aya and Kazumi Kishida, and his niece Mia Kawai) to be the pilots, and they are far more interested in their own lives.

There isn't a single person in Sakuradamon High who hasn't heard the legends about Seiji "The Mad Dog" Sawamura's demonically powerful right hand. His reputation makes it fairly difficult for him to approach girls, and after being rejected 20 times straight, he half-jokingly vows to finish high school with his right hand for a girlfriend. Much to his surprise, after waking up the next morning, Seiji discovers that his demon right hand has mysteriously turned into a miniature girl, Midori Kasugano, who reveals that she has had a crush on Seiji for the past three years. Because their situation is not ideal for either of them, Seiji attempts to return Midori to normal. But after causing a big misunderstanding at the Kasugano household, the pair decide to keep their predicament between them until a solution is found. Thus begins an odd relationship, and what could be the only chance for Midori to finally be with the one she loves.

When Kazumi receives a mysterious love letter from a secret admirer, should she cancel her first date just to save the Earth?

Reality and fantasy seem to be breaking down for student Kyo Sogoru. Is he really a smart but unpopular swim enthusiast at Maihama High School, or is he a pilot of a giant robot in a war-devastated world? Which life is real and which is fantasy?

Those incompetent aliens are still plotting to conquer the Earth! The only obstacle in their path is the giant, feminine robot ARIEL! But the young pilots have lives of their own... When Kazumi receives a mysterious love letter from a secret admirer, should she cancel her first date just to save the Earth? (OVA version of the movie of the same name)

To save the Earth from alien invaders and their giant monsters, Dr. Kishida does what any other red-blooded mad scientist would do: he builds a giant robot—the ultimate feminine fighting robot! Unfortunately, his granddaughters refuse to pilot it! Apparently, they've got more important things to do than becoming teenage super-heroes. Besides, how are you supposed to study for your college entrance exams while getting beaten up in battle? The fate of the world rests upon two people: Aya Kishida, one of the doctor's granddaughters, who may have to give up prep school to pilot the mighty (and lovely) ARIEL; and a mysterious alien named Saber Starblast, who may have the power to defeat the invaders once and for all...

There's an old decrepit building at the edge of the school grounds that hasn't been used for years, and it falls apart a little bit more each day. But the little house holds a secret, as Takahiro and his friends are soon to find out...they wind up making contact with a mysterious entity known as Saki. Can Takahiro save Saki's world from destruction.
