Akanko Marimo

About
Akanko Marimo is a protagonist in Prostudent Good, or rather a form of the protagonist Endou Gorou.

The cause of this is a magical baton made by Makutsudo Nobuhiko. The baton has his favourite magical pilot OC woven into it by some dark magic. It transforms the wielder if they shout the phrase "Banana, Banabana, Choco Banana!!".

At first she acts just as brash as Endou, but sprinkles in some femininity to throw off Makutsudo Nobuhiko and gets her way. As the game progresses she gets more used to being a woman and if continuously used will be stuck in that form. The upside to this form is that Sarasa now happily combines with Endou and Botan to form the Blastape Emperor.

Her mech is the Monkey Emperor which fights with a staff. This is upgraded to be able to fly later on too. Additionally this mech can combine with Botan's and  Sarasa's mech to become the Blastape Emperor.

Trivia

 * Originally Nobuhiko's OC, he made dubbing scripts for 52 episodes of her.
 * Her catchphrase whilst transforming is "Tropical Rainbow★ Shower!".
 * Her name is also an option in the Judo Tournament for Femdou in Prostudent Good
 * Overuse leads to being stuck as you'll be cellularly changed to a woman. This leads to Sarasa's end.
