Koyama was a special guest at SakuraCon 2016.

SakuraCon 2016 was a very lackluster convention. Its guest list that was furnished by its corporate sponsors like Aniplex demonstrate how far a convention can really go than people that most convention attendees want to meet.

Koyama signed along with Hiroyasu Kobayashi. They both seemed to have a good time interacting with fans. I was really impressed with both of them. I mentioned to Koyama that March 26 (the day the sketch was drawn) was my birthday, so he drew me a little birthday cake.
