RPG for interacting with nature.
The mysterious "Momonja-yama" where gentle monsters live.
There is a lot of nature left on the top of the mountain, including a lake that serves as a water source, a large river that flows from there, and scattered swamps and ponds.
The main character "Senri" and his younger sister "Yunna" lived happily together, but one day Yunna fell ill with a mysterious disease that keeps him from waking up from sleep. To wake him up, let him eat the scales of sea lions from a river somewhere. Hearing that, "Senri" takes his friends and goes on a journey of sea lions fishing!
There are fishing battles with fish, but not only that, but there are also various ways of enjoying it, such as completing an illustrated book by collecting insects living in trees and grass, plants and flowers by the roadside, and so on.
