Shachiku no Ore, Dragon ni Natsukareta node Pet Haishin wo Hajimemasu: Chibikko Dragon to Monster Bokujou Life

Decades ago, mysterious dungeons suddenly appeared in Japan. Monsters poured out, plunging the world into chaos. But thanks to international countermeasures, the threat gradually diminished. What was once called a fantasy world became an everyday reality for those living in the present. Joji Makise is one such person, exhausted from dealing with an unreasonable boss and endless overtime. One day on his way home, he comes across an injured, weakened baby dragon. Naming the dragon Ohagi, Joji uploads a video of their encounter, and it instantly goes viral. From dungeon explorations to meeting a wise old wolf, Joji's life takes a turn as he embarks on a dreamy slow-life journey, full of fluffy and adorable creatures.
