A tiny angry looking frog had been following you the last 10 minutes after you nearly stepped on it. It's a bit terrifying how something so cute could be so mad. Eventually, the tiny frog jumped up onto you and climbed up your clothes. This frog clearly has some beef with you.

So you did the most logical thing and took him home with you. Life with this frog was interesting. He was oddly intelligent for a frog and had chosen the name Katsuki after pointing at the name on a newspaper article.
