Mecha Protects the Earth

The war broke out on March 21, 2121. It was not an ordinary war, but a war against alien civilizations. Humans piloted mechas and bravely issued slogans to bring bloodbath to the monsters and return them to the earth. There is justice. There is a plan and a backup plan. Because I am a new writer, the novel is not good if you don't like it. Don't criticize.
