Butterfly Whales were once ordinary whales that fed on dead meat. They are a mythical creature that used to exist with "Hope and Dream" as their dreamlike foods. However, such non-existent food-like beings are not found in the deep sea ocean.
As time passed, butterfly whales underwent biological evolution, causing butterfly wings to grow and enabling them to live on land. They now look for their food, which is humans full of hopes and dreams, especially those who died in exchange for these things.
This is the most delicious food for butterfly whales. Unfortunately, the number of humans who still have hopes and dreams is decreasing day by day. Therefore, the butterfly whales will probably go extinct before they can try the most delicious food that they have always dreamed of. They are on the verge of disappearing from the world.
