[Comments from the Cast]

Shinji Kawada
“I love staying active and doing outdoor activities, so I’m truly happy to be part of a project like this! During the recording, Yuki and I had a lot of fun chatting about sports and voice acting. I’ll be right there in your ears, cheering you on—so please give it a listen. A small dose of courage can turn everyday life into a grand adventure!”

Yuki Shin
“I had the pleasure of recording with Mr. Kawada. While recording, I imagined where everyone might be walking… and how tired you might be feeling! It made the experience so much fun. I think we got to cover a wide range of topics. Once you reach the finish line, I hope you treat yourself to a delicious meal as a reward! Thank you for joining us!”

Ai Fairouz
“I love walking while listening to the radio, so I’m really happy to accompany you through your headphones as we walk together! Please enjoy the rhythm of my fun conversation with Yuki and make the most of your walk!”

Yuki Kuwahara
“Now that recording is over, I’m feeling super motivated! Why? Because Fairouz has such a wealth of knowledge about sports, fitness, and food—I’m supposed to be the one talking, but I ended up being a listener because I was having so much fun! I wish we could have talked even more… I’m sure you’ll enjoy walking while listening just as much. Let’s go on an adventure together!”
