The Demon Princess and the Phantom Soul Robot

The Phantom Soul Machine Weapon is an ultra-ancient magic weapon made by an ancient witch before the day God ascended. Powered by the soul of intelligent life, it is said that if used skillfully, one can control all magic in the world. At the same time, in the eyes of the goddess Eleanor, it is also the only method that can limit the "braves from another world" who were overrun by the abused otherworld summoning magic during the Demon King's subjugation war. Five years after the end of the Demon King's Crusade, Astrid Starlight, a demon princess who once longed for the human world, hid in the Kingdom of Lamisia as a magician and devoted herself to studying the relics left by her late teacher Milia - the Phantom Soul Robot. Finally, based on the success of deciphering ancient books, she performed summoning magic to summon the soul from another world - Zhang Zhouyu, who was numb to reality and addicted to video games. Therefore, Zhang Zhouyu, who was reborn as a Phantom Soul Mecha, and Astrid Starlight, who was hiding her identity as a demon princess, gathered their companions while exploring the world after the magic crusade. The riots of the Demon King's remnants, the heroes from another world with their own evil intentions, the ancient Demon God seals scattered all over the place, and the grudges between humans and goddesses. Among the intricate forces, the demon princess and the Phantom Soul Soldier jointly compose a journey towards their own souls.
