Saito Hiraga

Saito Hiraga was a normal Japanese boy who was returning from an electronics shop in Akihabara, a neighborhood in Tokyo, when he noticed a mysterious glowing orb of light. Saito was suck into the a portal to another world, being summoned into Halkegnia, a world with a roughly 17th century technology level, and as social structure similar to medieval Europe, ruled by magic-using nobles. Saito is summoned by a girl named Louise Francoise Valliere Le Blanc, a short, pink-haired mage in training known as "Zero" for her failure rate at magic. Saito is initially unable to communicate with anyone, but Louise inadvertently casts a spell that translates his speech while trying to silence him. Saito spends his first few days in Halkegnia, exploring an "academy of magic" (sound familiar from somewhere?), Louise having treated him exceedingly horribly. Saito inadvertantly angers another mage in training, and is challenged to a duel. Saito accepts, oblivious to the long odds of a non-magical commoner defeating a mage. The noble, Guiche de Grammont, agrees to let Saito have a sword. Saito discovers that, upon being summoned, he gained the power to wield any weapon with the skill of an expert. Saito gets a hold of a sentient, magic sword capable of blocking magical attacks named Derflinger, and later departs with Louise and several other to capture a mysterious magical weapon known as the "Staff of Destruction". Saito and the other members of his party are attacked by a golem commanded by a thief who stole the "Staff of Destruction". Saito get a hold of the staff and finds out that "staff" is actually a weapon from his world, an M72 LAW anti-tank rocket launcher. Saito kills the golem with the LAW. Saito later goes on the fight armies of enemies, shooting down a number of dragon riders with an A6M Zero fighter, using an AK47 and SiG Sauer P226, and even a Flak 88. Most impressively, however, Saito defeats an army of 70,000 (or 7 million in the anime) armed only with his sword, though he is grievously injured and only barely survives the encounter. Through their adventures, Louise and Saito gradually fall in love, in spite of Louise's abusive nature, beating Saito with a whip, attacking him with magical explosions, and forcing him to sleep on a pile of straw when he angers her.
