The action continues in volume 2! An ordinary middle-school student's

life takes a thrilling turn when he encounters a powerful

mechanical being in this exciting new manga series for fans of

My Hero Academia and Spy x Family.

Kita-Kagami City is a pretty normal town... except that some people

have gotten their hands on Mecha-Ude: powerful, sentient, mechanical

beings that attach themselves to their human hosts and

have awesome capabilities.

When middle-school kid Hikaru accidentally activates Alma, a robotic

arm Mecha-Ude that has no memory of its past, they form an

unlikely bond. But where did Alma come from? And why are shadowy

secret organizations suddenly chasing Hikaru, stopping at nothing

to steal Alma?

Together, Hikaru and Alma must uncover the truth behind the Mecha-Ude's

identity and prevent it from ending up in the wrong hands.
