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

Synopsis

Kiska, a boy who was mistreated by the villagers, was able to get by thanks to his childhood friend, Namia, who was the only one who stood by him. One day, Namia is found murdered in the village. Kiska is framed for the murder by the other villagers, and banished to an inescapable S-class dungeon...? This is an otherworldly revenge fantasy that makes full use of the skill "Save & Reset" to get back on your feet no matter how many times you die! (Source: Kadokawa, translated)
