A nameless girl with golden wings appears in the forest while Roy walks alone in his camping trip. She’s the last Firebird that humans are trying to hunt for her blood. They believe in the ancient mythologies that said Firebirds are rare mythical creatures that have a unique blood type G that cures any disease. Humans have been hunting those creatures for centuries. Roy falls for her exotic beauty, and innocence, and tries to keep contact with her. He keeps this secret to himself as he has one mission now, which is to protect the last Firebird on Earth, and find the safest place, the Merry Kingdom.
