So, at school he tries to hurry and usually finishes his homework during homeroom, and once at home he can rest or do whatever he wants with his time.
Suddenly, a messenger arrives with a package for him, intrigued, he decides to open it and finds a strange lamp inside, he thinks it is a joke and puts it aside, but once he yawns, something happens and the lamp show its power.
Akubi appears, ready to fulfill Kantarou’s wishes, but he is not enthusiastic at all. And when he sneezes, the lamp reacts again, this time, Hakushon Daimaou appears ready to start a new adventure.
