Riru Whale♀

The legendary whale goddess of the island herself. For some reason, she has lost her power, and she also claims that it has been a long time since she last appeared in front of humans. She met Yuuma by chance, after Yuuma fell down the waterway and got swept up the mountain and landed right in front of her shrine. Her favorite food is canned mackerel, which she starts loving after buying it from the convenience store with Yuuma. Due to being a goddess, Riru understands the structure of the world and other things well, especially everything to do with maths and physics, however, she has misconceptions about some of the things humans do.
