The concave-convex world is happily chasing Vidiant. Yueran is a character in the cartoon "Bump World". "Bump World" Season 3 Episode 00, Yueran followed Bump Contest all the way to hunt down the target Vidiant. I accidentally became a contestant in the concave-convex contest and made my debut in the prequel of the third season. At first, she was chasing Vidiant, but because of Guimi's intervention, she gave up hunting.
