Junk: Record of the Last Hero

Junk: Record of the Last Hero is a manga written and illustrated by Kia Asamiya.

Plot
Junk, is a system which acts as a super-suit, and the people to whom the junk suits are given. At first, there were two units in the world, both in Japan; one white unit and one darker, black unit. However, it was revealed that a third JUNK type (red) was also created. The Black JUNK, White JUNK, and Red JUNK were all prototypes used by JUNK SYSTEMS to further develop the Blue JUNK (the production model). The eye style, according to Asamiya, "Is a mono-eye style.... but there's actually two eyes." The suits require an eight hour charge up period, and only one hour of performance is delivered. Though the suits are free, users must fill out a report and send it to the manufacturer, which has not yet been named.

The story revolves around the two users of the Junk units, one of which is Hiro, who receives the black unit. The other unit goes to an unknown female user, though hints suggest it is Manami. It is actually revealed later that the White Junk actually goes to Manami's Stand in/bodyguard, Lisa. The story follows Hiro's maturation and adventures using the junk system, as he copes with the responsibilities and burdens it brings, as well as the changes in his life because of the suit.
