Kurogane no Linebarrels

A fourteen-year-old boy experiences a life of average hardship, often mocked by peers and daydreaming about heroism. This changes when an unexpected event gives him a girl and a massive humanoid machine known as "LINEBARREL." Gaining this immense power thrusts him into a series of conflicts, schemes, and relationships. As he navigates these experiences, he begins to understand life more deeply. He forms new bonds, loses others, and takes on significant duties, learning to face the world around him.
