Dungeon Oji-san

ダンジョンおじさん

In 2039, the world has been transformed by artificial intelligence into a real-life RPG. Humanity now lives as players in this fantasy-like reality. Ji-san, a middle-aged man resurrected by the AI's influence, spends his days diving into dungeons, consumed by despair.

One day, he obtains the Taming Sword, a weapon that allows him to capture monsters. Instead of focusing on defeating the demon king or conquering the world, Ji-san becomes obsessed with collecting monsters. This is the carefree fantasy of an old man who prioritizes his monster-collecting hobby over any grand quest.
