Comment by Ryogo Matsumaru about PokéDoko
I'm Ryogo Matsumaru, and believe it or not, I've just become the leader of a group that's going to expose the world to the wonders of Pokémon in "PokéDoko"!

I've loved the Pokémon shows to the point of admiration ever since I was little, and I still can't believe I'm actually going be in one as a host this time. The show hasn't even started yet, and I'm still moved to tears. I will do my absolute 100%, no, 100000% best to show how amazing Pokémon is...!

I'm really looking forwards to visiting Pokénds all over the world with Abareru-kun and host Shoko Nakagawa.

These will be encounters created through Pokémon. Let's go to a world where excitement never ends!
