    In 2016 January, at a game music event held in Japan, Motoaki Furukawa saw Mecha Ritz: Steel Rondo and contacted the developer Shohei Yuki, to create a game together.

    They started a crowdfunding project in the same year July on Makuake, a Japanese crowdfunding site.

    The crowdfunding was successful, with reaching and exceeding their initial goal of ¥1,000,000 in 9 days, and ending up rising total fund to 228.6% of the goal during a couple months the project was open.

    The game was being developed and successfully released at Febuary 2017, and is being sold on various Japanese online shopping malls, including Akiba-Hobby which officially sells the game to outside of Japan.


    Momoko is a genius high school student, who is not getting along with others in her life.

    One day, Momoko happened to find a weird looking animal and saved him, who turned out to be from the underground world, and named Grave. As appreciation, He told her about the existence of the underground world, a paradise for animals where human government doesn't reach.

    Momoko decide to connect the surface and the underground. And therefore so-called 'Pinky Project' has been launched.

    Aoba and Akane are classmates of Momoko, looking for a part-time job that is happened to be offered by a company named 'IOQ', in which Momoko is a boss.

    Their job was transporting resources from mountains, needed to reinforce the gigantic Leonard Tower so it can be connected to Shibuya IOQ in the surface, using a small fighter plane named 'Pinky Salt'.

    At the last day of their job, Aoba and Akane discovered the purpose of the job. Monsters from the underground will going to appear on the surface, Momoko should be onto something.

    To escape from the underground, and to stop Momoko, Aoba and Akane pilot Pinky Salt.

    Then, Momoko's voice is being broadcast loudly through PA systems all over the underground.

    "Two humans! They have ran away to somewhere in the underground~! If you catch them I will grea~tly reward you! It's to~tally okay whether you catch them alive, or in some cases, dead!!"

    Akane and Aoba looked at each other.

    "Aww, we are gonna be murdered... aren't we?"

    "No, we are escaping the underground alive! And, we are stopping Momoko's madness!"
