"Created many great inventions in an effort to overtake her childhood friend Rouche. After much blood, sweat, and tears, she has finally succeeded in developing the Pursuit Bit." -Mialy's in-game description.
"In spite of her recent success, Mialy still continues her hard work as an inventor. She has modified her weapons again in another attempt to best her rival, Rouche." -Type.X's in-game description.
"Mialy, who hates to lose, works harder than anyone else. As her rival and junior have both been improving, she's been frantically developing new inventions." -Type.H's in-game description.
"In the spirit of Halloween, Mialy has equipped pursuit bits with a cat motif. She put her pride into making them after being asked to help with the event." -HW's in-game description.
"Mialy created a special bouquet-shaped weapon and chose a dress to match it. The classic appearance of her Organdy train matches the miniskirt she chose almost too well." -WD's in-game description.
"Between her constant traveling between dimensions for press conferences and lectures, Mialy always finds time for her inventions. She's incorporated her research into her weaponry." -Type.T's in-game description.
A Garapon Mecha Musume from the game Cosmic Break, Mialy is an inventor who, like Rouche, has an incredibly competitive personality. In-game, Mialy is an Artillery Bot introduced in the Inventor Gara with a cat theme and obviously focused in fan-service, with long, red hair tied in twintails and thin clothes that barely cover her chest and leave her panties exposed.
Mialy and Rouche are constantly trying to outsmart each other by building the best weapons, although their competition apparently always ends in a draw. Mialy focuses on powerful railguns and Pursuit Bits, portable railguns whose purpose is to follow and eliminate designed enemies without endangering the user. Her constant inventions resulted in 6 alternate versions in-game with different, but similar, weapons: Type.X, Type.H, HW, WD and Type.T.
Some time after Mialy invented her Type.X weapons, she met Illumis, a young inventor who viewed her as a role model, and who soon improved so much along with Rouche that Mialy, struggling to keep up, built Type.H. Soon, Illumis also joined the competition, being on par with Rouche and Mialy, but also helped Mialy when possible, leading to several breakthroughs, as stated in Illumis' Type.Q's description.
