Escaflowne (es-cah-flow-nay) is from the 90s. It's about a girl from our world that gets transported to Gaea (guy-yah), a world of dragons, humanoid species, and mechas called Guymelefs (guy-mel-ef).

He is one of the Knights of Caeli, an elite group of swordsmen from Asturia. His past is checkered with bitterness and death stemming from his father's fascination with the Mystic Valley and Atlantis.

Asuna YΕ«ki comes from the Anime Sword Art Online. It takes place in near-future Japan where full-dive virtual reality is possible. The game, Sword Art Online (SAO), premieres as the first VRMMORPG of its kind. 10,000 players enter the game world of Aincrad (eye,n-krad) on the first day. Soon they discover they are trapped and that if they die in-game they die in real life.
Asuna is not a damsel. She is (excuse the cursing) a bad ass bitch with a blade. She becomes one of the strongest players in the game and in her guild Knights of the Blood. Her moniker is "Lightning Flash" because she wields her rapier in a swift and deadly fashion.
As the game progresses, her softer side is shown when she and Kirito form a relationship and adopt an NPC AI called Yui.

There is no way to describe him other than he's crazy as all eff, seriously deranged, and psychotic to boot. He has a tendency to go overboard on his enemies in a fight.
As an ageless creature, Alucard is the ultimate vampire. He is all powerful and very bored. His ennui leads him to turn Seras Victoria, a police woman, into a vampire.
He works for Sir Integra Fairbrook Wingates Hellsing, a woman that takes no sh*t from anyone but deals a great deal onto her enemies. She runs the Hellsing Organization, which is responsible to protect England from vampires bent on destruction.
His archenemy is the Paladin Alexander Anderson who works for Iscariot (Vatican Section XIII) a top secret section of the Vatican. He is as insane as Alucard.
