>>24467785Ulillillia views the World as being primarily composed of 10 separate elements (Fire, Ice, Thunder, Earth, Poison, Wind, Water, Holy, Gravity, and Dark). This is important, because to him the nature of these elements dictate what is and is not possible both in the real world and in his imagined world, which is where the book takes place. The plot of the book itself centers around his imaginary friends, which are less human (despite the fact they are described as human) than they are entities that loosely embody a combination of certain simplistic concepts and characteristics that Ulillillia finds intriguing.
The plot is about an alien that assists 3 teenagers in stopping the villainous Seth King, who wants to gain power over the 10 elements to enslave the World. Half the book is just sillyslop Azumanga tier filler though.
