My Last Respawn: Terrorist Ri

Swords & magic, modern & advance technology, mythical & demonic creatures, fantasy worlds & outer-space, systems and superpowers, Ri woke up from his last and final respawn after his death in a world he called Hell. Only to see carnage before his eyes and a lunatic piloting an X-series 700 infantry Mecha causing a mass genocide. Desperate for answers, he killed and ran. Ending up awaking in a white room with an A.I. tending to his injuries. Now he has soul decline. A severe condition that was akin to cancer meant for souls. With only one year left, he embarks in a journey once again to find the witch whom he had been searching for so long for so many of his lives... in order to kill her.
