The "Yaksha" from ancient Indian mythology is regarded as a demigod. It was born from the sole of Brahma's foot. Sometimes it is a beautiful young man, sometimes it is an old dwarf. It has two faces and two personalities, both compassionate and cruel, which symbolizes the mutual support of the identical twins Arimu Jing and Amamiya Rin (played by Ito Hideaki). The two are twins created by high technology, with abilities and IQs beyond ordinary people, but due to the completely different growth environment, they have completely different personalities and destinies. The elder brother Jing spent an ordinary and happy childhood, and was later sent to the United States to study and became a scientific researcher; while the younger brother Rin was raised in secret and had a gloomy heart. The two who had little intersection changed because of Jing's return. Jing, who went to the island to investigate, opened Pandora's box, and all the evil and beautiful stories were revealed. And who is Yaksha, in fact, it is no longer clear... This film is adapted from the cartoon of the same name by cartoonist Yoshida Akio.
