I'm just broke's manga / #Slime(2)

Super cute story about some rare gloopy slime with their adorable owner. Which is a no Star Tamer.

Art is beautiful - - - One day, a large hole suddenly appeared in the yard. There was a mysterious slime with a metallic body that was trembling and shaking. For some reason, Yuuma Mitaka, a dull high school student, spends his days exterminating the “metallic slime” that springs up in the hole every morning. As he repeats this daily routine, Yuma’s body undergoes an astonishing evolution! - - - No other comments other than this deserves a higher rating. It's not bad
