This archipelago is far from any other large islands or continents. You were assigned the teacher of the small school in the archipelago and found the predecessor’s notebook. This notebook indicates that there are an uninhabited island where lots of newly-discovered butterflies live. Island's residents have known the butterflies since early times, but they don’t think these are extraordinary.
