Mechanical Arms

Hikaru Amatsuga, an average middle schooler, is partnered involuntarily with the Mecha-ude Arma, a rare and special existence. As part of this partnership, a resistance group called ARMS assigns Aki Murasame, a dual Mecha-ude user, to follow Hikaru to protect Arma. Aki is also searching for a Snake-Type Mecha-ude wielder who has put her comrades at risk, while the Kagami Group is seeking the "Trigger Arm," a mythical Mecha-ude said to grant unlimited power. Hikaru and Arma must work together to find the courage to fight back against the Kagami Group.
