Trivia[]
- Kappei Yamaguchi’s thoughts on the death of Atsuko Tanaka: I am at a loss for words at the news of Atsuko Tanaka-san's passing. We worked together on various projects, but Beast Wars and Destroy All Humans! left the strongest impression on me. And we were neighbors. We've also talked about going out to eat with our family sometime. I pray for your soul to rest in peace. I wonder if Hikaru-kun is okay…
