Yuuki is a mahou shoujo (magical girl) fanboy. Thanks to Hermod's magic, he now transforms into a magical girl himself. Yuuki is the new valkyrie and is charged with protecting Midgard and Asgard from the forces of the fire giant Surt.

He is an average student. He could make better grades, but he really doesn't put any effort into his studies. He prefers to pursue magical girl anime, manga, and merchandise. He lives alone, as his father is constantly on business trips.

Hermod is the god of messengers in the Norse pantheon. He sides with the Aesir, which is lead by Odin. Hermod was sent to Midgard (the mortal realm) to find the new valkyrie. He decided that disguising himself as a magical girl DVD was the best way to find one.

No one is sure what kind of animal Hermod is supposed to be. He claims to be a marmoset, but some say he's a "one messed up little critter, I tells ya."

Myu Myu-chan the Auroch is the first beast that Yuuki faces. He is not so much dumb, but easily confused. As the large bull auroch, he is capable of destroying city blocks in a matter of seconds. But as a small "lawn-cow," he is capable of being run over by cars.

Myu Myu-chan is currently living as a pet with Chiaki, who named him.

Surt is the leader of the fire giants and Muspellheim. He hates the Aesir for hunting his kind and forcing them to live on the fringes of the universe. He wants to get revenge and waits patiently from the edge of Muspellheim for his chance.

Shuzaya Chiaki has only one want in life: to be in a magical girl story. While this may seem silly, magical girls are everything to Chiaki. She believes that there are magical girls in this world. There just has to be. She doesn't know how right she is though.

When Chiaki is not looking for magical girls, she is buying magical girl merchandise or taking care of her new pet, Myu Myu-chan, who she is convinced is a magical pet of a magical girl.

Himuro Taki is a student at Montrose Academy East, where he is a office worker some of the time. Taki likes Montrose Academy East because of its strange and varied curriculum (meaning he can study Norse mythology with no problem). He also likes girls who are strong and have something unique about them.

Loki was a giant who was found by Odin and his brothers. Despite their hatred of giants, they thought he was awesome, so Odin made Loki a blood brother, thus making him one of the Aesir.

Currently Loki is chained under the earth with a snake dripping poison into his eyes because of the whole Balder incident. Loki's whole take on the incident was the that "the little snot had it coming to him." This defense didn't help him.

Loki is able to project himself into the body of a stuffed white cat, so he is able once again wander Midgard. The knife he carries is for "little children and dogs that have the stones to pick [him] up."

Loki really likes Yuuki. A good thing?

Odin is freaking awesome, and that's all you need to know.

Thor is an easy going sort who enjoys a good fight and loves to party. He used to hang out with Loki back in the day, but the whole "Balder incident" puts a damper on that. Though with Loki's current freedom, that may change.

Thor has been put in charge of Yuuki's training seeing as though Hermod knows about as much about fighting as Myu Myu-chan knows calculus. He will be a very strict teacher, of course...

Good luck, Yuuki-chan!

Heimdall works his boring job of watching Bifrost. He wants to be doing something else, but he's stuck there forever, at least till the end of the world.

He spends a lot of time making fun of the giants with Tyr and reading.

Tyr has nothing better to do with his time these days than to torment the giants, which is pretty fun. He's missing a hand because of his stupid stunt with Fenrir. Though you have to admit, that was pretty cool.

Hilda was the valkyrie before Yuuki. She quit to marry her fiance, but probably just used marriage as an excuse.

Even though she's no longer a valkyrie, she still wants to keep in touch with the Aesir.
