the art is impressive, and the story seems promising, but it's too short to really judge it. Reading it takes a very short amount of time, so if it piques your interest, you might as well give it a go.
Rikka is a kid who fell down from the sky with weird equipment attach to his head which makes him see alien, fairy or demon (Page 1, 8, 12). His friend Gera tries to get him medical care by being a thief. - It's nice but instead of one shot it's more like a prologue of long series.
