My Yandere Girlfriend Hiding in the Dungeon Kills Me Over and Over Again

The judge announced, "The defendant, Kiska, is sentenced to exile in the depths of the dungeon for the crime of murder." Kiska was to be banished to the far reaches of the dungeon via the teleportation array due to a false accusation. Kiska had the same hair color as the family that had betrayed the humans, and he was persecuted in the village. In the end, he had been made to bear the blame for a crime where the village chief's son killed the one Kiska loved. He loathed them. He hated them so much that he wanted to kill every villager who had scorned and humiliated him. While he harbored such thoughts, for Kiska, who had no skills and was not an adventurer, being exiled to the depths of the dungeon was tantamount to a death sentence. However, "I will help you." As he was about to be attacked by monsters and sensed his own impending death, someone declared that. "The name of the skill I'll give you is 'Save & Reset.'" Thanks to this individual, he obtained a skill. With this skill, Kiska could rewind time to just before his death, even if he were to be killed by monsters. It seemed like he could now avoid death, but this marked the beginning of his descent into hell. This is the story of an ordinary man who possessed no power except the ability to return from death, attempting to conquer the most formidable dungeon, dying repeatedly in the process.
