Hidden Mystery

Why are the magical world and the "technical world" connected? Why would the noble Golden Feather Clan put down their posture to help mortals in another world? Why do bloodthirsty beasts abide by their contracts with mortals? The gods above are also willing to listen to the prayers of mortals and send down their divine power to protect one side. The mysterious organization that studies taboos, the deep-sea secret clan that covets the mainland, the magic society with ulterior motives, the powerful native beasts, the demons who covet the world, the seductive darkness, the fantasy race from another world, the giants and dragons who always look at the sky and the earth, what kind of secrets are hidden behind all this?
