Season 1

Wataru Hoshibe and his cousin Kakeru Amabe prepare to stream on RyuTube, when they are suddenly pulled into the parallel world of Chubukai.

Wataru finally reunites with Kakeru, but a prankster is harming the local villagers...

Ryun Ryun has been busy taking care of Wataru and the others since morning. While looking at the map, Wataru notices a reaction from the Rainbow Blocks nearby, but Ryun Ryun seems to be acting strangely and his directions are unreliable. When they finally arrive at their destination village, the villagers see Ryun Ryun and run away. Wataru and the others are confused when a "Honhon" that looks just like Ryun Ryun appears!

While Wataru and Co. are relaxing in luxury, Kakeru, Sho and Mygah find themselves lost in the jungle.

Kakeru finally remembers the face of the person who had captured him and it's... Offline?!
