I understand the design philosophy behind most of the scene and its a homage to OG ultraman hayate. If you have been watching ultraman since your childhood you know ultraman is actually a dark and entertaining story with alot of meaning treat it like eva. It is depressing at time but ultraman signify the light to your dark times. Thats why hikari is a word been used over and over again. If your new and just judge based on omg idk whats going on go and find the meaning behind it there.you may find your answers.
