Rhiannon is the fair and gentle daughter of a village chief. Unfortunately for her, she's also exactly the sort of maiden who is needed as a sacrifice to wake the Demon King Arawn from his thousand-year slumber and is soon kidnapped for this very purpose. However, when Arawn is summoned, he decides to spare Rhiannon's life, instead killing her captor and freeing her from mind control. Taken with his kindness, Rhiannon immediately decides to marry the Demon King, making him the new village chief. All of this is bad news for Rhiannon's protective but hot-headed brother Arthur, who must now pledge his knightly service to his new Lord, Arawn. Together the three of them must journey and together they must fight, encountering new friends and new foes along the way.
Both main characters are summoned from another world/dimension. They both are sword users but in tears to tiara the main character is highly skilled from the start. They are both harems with many different women falling in love with the main character, but Zero no Tsukaima is more open about that. If you like adventure, wording fighting and magic fighting either one is a very good choice.
Seeking a cure for his depraved masochism, Taro Sado approaches the Second Volunteer Club on the recommendation of his best friend, Tatsukichi. There he finds the help of the violent but kind Mio Isurugi who promises to beat the masochism out of him by any means necessary. Will Taro be able to survive the assaults of this upperclassman, the overly-affectionate attentions of his mother and sister, and still lead a normal school life? Unlikely. But will he get over his perverse fetish? He sure hopes so.
Lotte, the princess of Ygvarland, hates men - a fact that ordinarily wouldn't be a problem given she's just a child. There's just one issue: the girl is a succubus that must suck the life seed from the male species or die! Now approaching adulthood, Lotte must learn to tolerate the opposite sex, but her royal highness won't have any of it. That is, until Judith, the girl's lady-in-waiting, brings Lotte a human boy to the demon world. This unfortunate young man, Naoya, must now open the princess's heart to his gender, but as caring and considerate as he may be, he'll certainly have his work cut out for him!
Cecily Cambell just wants to be a Knight and protect her home like her father and grandfather before her. There's just one problem: she’s incompetent! During a fight with a crazed swordsman, Cecily’s cherished blade breaks; and just as she’s about to be cut down, a man named Luke comes to her rescue wielding a katana - a blade unlike any Cecily has seen before. Together they must ensure that the Demon Sword Aria doesn’t fall into the wrong hands, and Cecily alone must prove herself worthy of her very own katana.
Zero no Tsukaima (or Zero's familiar) and The Sacred Blacksmith remind me of each other, mostly because they both inherently put most of their time into combat or a little of romance between characters present. Zero is much longer and more drama/romance driven than The Sacred Blacksmith (it is also more wacky) but they both juggle those two concepts constantly.
The year is 2022, and gamers have lined up on launch day for Sword Art Online, a hotly-anticipated MMORPG that lets players connect to an immersive virtual reality world with special helmets called Nerve Gear. Kirito is one such gamer who's eager to jump back into action, having spent a great deal of time as a beta tester, and quickly becomes friends with newbie warrior Klein. But soon, Sword Art Online's 10,000 players discover that not only are they unable to log out, the only way they can return to their physical bodies is by beating the 100-level tower's final boss - that is, if their HP doesn't drop to zero first, for death in the game means death in the real world. Now, with no one else to turn to, Kirito and the other participants must survive the game as best they can – some forming guilds, others ruthlessly leaving their peers behind, and many tragically falling by the wayside or to the merciless monsters populating the lands...
