Comments from the Guest Cast
Sato Keigo (JO1) — role of Shibuya townsman
“Thank you so much for this opportunity to lend my voice to this film! Keroro Gunso is an anime I’ve watched since childhood, so it feels amazing to be involved with it professionally. This time I’m playing a delinquent who’s been possessed by a ghost and had his personality changed — I tried to bring out the inner delinquent in my character to the fullest. I hope you’ll look for me in the film!”
Yagi Yusei (FANTASTICS) — role of Shibuya townsman
“I had such a great time being a guest voice actor this time around. Keroro Gunso is something I’ve loved since elementary school — both the manga and the anime. I can honestly say it’s a part of my childhood. When I got the call from Director Fukuda, I accepted right away. I hope you’ll come see it in theaters!”
Suzanne — role of Kumamoto news anchor
“I woke up at 5:30 in the morning to travel from Kumamoto for the recording session! There’s a scene set in Kumamoto in the story, so I poured all my love for my hometown into the performance. Keroro Gunso is such a heartwarming series that people of all ages can enjoy — I’m personally looking forward to taking my son to see it in theaters!”
Watanabe Rina (Hinatazaka46) — role of Shibuya young woman
“I love Keroro Gunso so much, so when I heard this news I was both surprised and thrilled to be part of it. Even though it was my first time doing voice work, I had so much fun during recording. I hope both longtime fans and those who’ve never seen Keroro Gunso before will come and experience its world together!”
