There are scenes where characters are using items that look like super advanced computers..that float. (Crazy stuff like that) For some reason i feel like i should have seen these two things being used together but i havent. This is one of the only times when ive seen super advanced technology and supernatural elements being used together. (Supernatural meaning spirits and etc.. not aliens.) it is also interesting to see that this film uses magic and the image of being power to their advantage when making relationships and love interests.
In "Samurai from Outer Space" there are examples of how super powered women are attracted to ordinary, basic men. This is a popular thing that is done today in anime because as ordinary people we like to be able to read about other ordinary people having beautiful powerful women attracted to them. Some people may even see themselves in situations like it, which is why they are able to fantasize about it, which is important. Putting the reader in the story itself helps keep it interesting.
