The game is set in a familiar mythological setting where the war between Angels and Demons has existed for over 1000 years. The gods of Heaven won, sealed the Devil Drastral into an artifact, and hid it in a temple deep in the forest. 5000 years have passed, and mankind has created a new world full of prosperity.
Everything seems perfect until one-day monsters appear – they attack the temple that seals the Devil to free their Boss – Drastral ☠️. The Angels saw this, so they quickly sent the Angels Guardian down to the world to destroy the enemy and protect humanity.
