I was on an ANA flight and hadn’t seen Demon Slayer yet. I thought “let’s take a look” as it was so popular and watched Episode 1. Then I got hooked on Demon Slayer. The opening was devastating and I wanted to know what would happen next, and the picture was so beautiful. The animation technology is impressive nowadays. I felt like walking in snowy mountains myself.
