Zero no Tsukaima, Kono Subarashii Sekai ni Shukufuku wo! Recommendations
*Both series involve a human male lead being summoned/reincarnated to an alternate fantasy world...
* Both female leads (Aqua & Louise) have an amazing abusive personality...
* Both have Harem/Comedy combo ( the shows themselves proves that this combination is awesome )
*Both have Mages/Dragons/Swordsmans/Spells ( a so called RPG feel in them )
Both revolve around a main character that is plunged into a fantasy worlds with magic in them.
In this world the main character learns to live in this new environment.
In Outbreak Company the MC is treated as a guest while in Zero no Tsukaima the MC is treated sort of like a slave.
