Terra Formars Gaiden - Rain Hard

Adolf Reinhard, a senior German representative of U-NASA and the world's first successful M.O. surgery subject, is assigned a secret mission before departing for Mars. The operation forces him to confront lethal enemies and the painful circumstances that shaped him, revealing the harsh life of one of Terra Formars' most tragic fighters.

Terra Formars Gaiden: Rain Hard is a short seinen science-fiction spin-off focused on Adolf Reinhard. Set before the Mars mission, it expands his background through a covert assignment involving M.O. surgery, military action and the same brutal bio-engineered conflict that defines the main Terra Formars series.
