This comedy series describes the story of a village boy (Yoshihiko) who is chosen as the one hero who can defeat the villainous Maou. And so he sets off, quickly acquires a band of three others to help him in his quest, and together they fight various fights, or seek treasures.
In other words, it’s an RPG. In this show the conventions and clichés of role playing games are constantly parodied. It references Dragon Quest in particular, but you only need a passing knowledge of Japanese RPGs to get the jokes.
The jokes come thick and fast, so there’s no danger of being bored. It’s cheap and cheerful, and full of energy. It’s clearly written and made by people with a lot of affection for RPGs and watching our heroes face inept enemies or get distracted by side quests for absurd magical items is great fun.
If you've ever played an RPG and wished that, just once, one of the characters would remark on how predictable it all seems then this is the show for you.
