Code of Rainbow: Soaring Flame and the Dragon-transcending Magimal
Some say this book has a harry potter feeling, but it's a completely novel story and unique magic world. The world is beautiful because it's full with magic elements of seven types, each in a designated color - just like the rainbow code! That said, those colors could only be seen by some special eyes, such as Soarame's!
Many animals in this world possess magic power, so they were called "magimals". A well-known example is dragons, and we all know how strong they are. However, they are still not the most powerful kind of magimals, because each type of magic has a king kind - and never underestimate a magimal just because it looks cute and little!
