After accidentally transmigrating to a parallel world, you discover that the monsters and Ultraman from tokusatsu shows are no longer fictional. They are real.
To better respond to the successive appearances of vicious monsters and invading aliens, Earth's Defense Force establishes the Special Defense Force, or SDF, equipped with the latest technology.
Having been given another life, would you choose to live as an ordinary person, or join Earth's Defense Force to protect others?
The focus is on friendship, with an immersive perspective. Please note: the immersive perspective is for female readers only. Otome pairings are fine, but no shipping BL.
Thesis: May the world be at peace
