百万吨级武藏

In a seemingly ordinary town, people live a peaceful and fulfilling daily life. However, they don't know that all of this is actually just a false peace, and the earth is already facing a huge crisis.

The unknown fact is that the earth has been attacked by mysterious aliens in the universe, resulting in the death of 99.9% of human beings. These mysterious alien enemies are called "Dractor", and their aggression has made the earth precarious.

In the disaster, a huge cave appeared on the earth, forming a suitable environment for aliens. Human beings can only hide in shelters, waiting for the day when they will return to the ground and rebuild their homes. In this dark refuge, people's memories have also been erased, and they lead a different life than before.

However, in this forgotten land, there is still a group of brave people who are called "The Chosen Ones". These special people become the pilots, driving the huge robot called "Rogue", and start a life-and-death confrontation with aliens to defend the last hope of the earth.

In the refuge named "Shelter Ixia", the pilots receive training, constantly strengthen themselves, and prepare for the next battle. Every choice means a challenge to the unknown, but these pilots bravely faced the test of fate.

Every day, new pilots are selected to join the ranks of defending the earth. Their mission is full of honor and sacrifice. In order to protect their homeland, they will fight the alien invaders without flinching.

"Musashi Megaton" animation tells the brave journey of these pilots. They will face unknown enemies, challenge their limits, and fight for the future of the earth. Let us look forward to witnessing the growth and victory of these brave men!
