Review Detail of Lane in Marvelous Mecha

one chapter mc is hardened orphan growing up on a prison planet, the next he kind hearted escorting a family to safety, then the next he crying as he ends the the pain of a dying mech pilot, and as shows his admiration for the Chinese spirit. The problem is all the filler characters like he does not even describe the father, mother, and two teenage daughters then they are gone. so over powered mc, old deceitful grandpa's, beautiful girls who are ther as plot filler then disappear. I lost interest
