Yuusha Yoshihiko to Maou no Shiro (2011)

Both of these dramas strongly utilize an off-beat, random style of comedy strongly driven by eccentric characters.

Slapstick humour, silly, parody, breaking fourth wall. Both are famous epic comedy parody........................

One is a mashup of classic Japan/epic samurai stories and sci-fi, the other a real life version of old school rpg games, and they share the same brand of silly fourth-wall-breaking humor, the same way of making fun (in an affectionate way) of beloved classics and the same way of mixing up ancient and modern. They're different stories but have a very similar vibe!

Both are absurd and full of nonsense, yet extremely funny.

Both are directed by Fukuda Yuichi. Slapstick humour, silly, parody, breaking fourth wall &.......... Swordplay!!................................. Both are very similar.

Slapstick humour, silly yet Badass demons, parody, breaking fourth wall &.......... Swordplay!!.................................

Because they are both about fantasy/rpg type games happening in real life. Yuusha is funnier, but both are enjoyable to watch.
