Season one left you with three kids who barely knew each other forced to pilot a machine they don't fully understand, in a shelter where their own memories are incomplete weapons. Season two stops pretending the real threat is outside. The invasion was the easy part. Now they have to survive what the people running the shelter actually want from them, and whether saving humanity means staying alive or staying human. The mecha still looks like it's held together by desperation. That's the point.

MEGATON MUSASHI Season 2 is the second season of Megaton-kyuu Musashi, a mecha science fiction TV series that runs for 15 episodes. The franchise is set after an invasion has wiped out 90 percent of humanity. The survivors live in a shelter where their lives are watched and their memories of the invasion have been erased. Three teenagers from the shelter pilot three machines that join together to form Musashi, a robot built from Megatronium alloy, and the story mixes robot action with school life.
