Sparkling Generation Valkyrie Yuuki/WMG

Freya is Yuuki's mother.

 * Yuuki has her mother's eyes
 * Bonus now they've started glowing, even Otsana seemed to notice the similarity.
 * Sure doesn't have her boobs, though.
 * Give her time; she's still growing.
 * And that idea would be Parental Incest since Freya did try to rape Yuuki.
 * Well, Brother Sister Incest happens pretty often in Norse myth...and, in Freya's defense, if this is true then she thinks she has a son, not a daughter. So she's not expecting to have to worry about fondling girls.

Heimdall is Yuuki's father.

 * Yuuki claims his Dad is always away on business - guarding Bifrost perhaps? Why else would he wear a modern suit?
 * Aren't these two guesses mutually exlusive?
 * Not necessarily, if they were both on vacation at the time and somehow didn't recognize each other.
 * If memory serves, Freya also has a missing husband, some guy who went out on a trip and got lost or something. Yuuki says his dad's away on business a lot. And it seems she's recently ditched a second husband in the comic universe.

Odin is Yuuki's father.

 * He is the All-Father, after all. He has quite a reputation for wandering and has spent a lot of time on Midgard lately. And something's up with the door to Yuuki's dad's room.

So Why DOES Ribbon make superior armor? Legions of Anime fans are just dying to know.

 * Rule of Sexy, of course. Why do you think Valkyries have to be female in the first place?
 * Tradition. The ability to alternate between bulletproof and soft, like some sort of super-silk. Works as Plot Armor when placed (or set to unravel if damaged) where Clothing Damage would bring the rating higher than the author wants. But mostly tradition. Also protects against poison, petrification, mind control, and all manner of underhanded tricks.
 * It's also wolf-proof, as shown in the original Eddas when chains failed to bind Fenrir
 * It isn't. Thor was just humoring her.

Otsana was meant to lose

 * Freya recognised that Yuuki was too weak to serve as the Valkyrie, so she sent Otsana and Shebi after hir, knowing that their powers would be drained to make Yuuki stronger.
 * More likely Freya doesn't really care who wins or loses. If the new Valkyrie proves herself strong enough to win, good. If she isn't then Otsana and Shebi kill her, which is also good.

Yuuki's costume-manipulation isn't because of some mystical inner magic

 * A valkyrie's powers stem from her nature, personality, hobbies, and lifestyle. Why can Yuuki manipulate hir costume, then? Simple: It's because (s)he's a cosplayer!

The Power Stealing Thing

 * There is one thing not explaned how do you think Yuuki has the ability to steal powers

The thing Otsana said

 * When Otsana says Its almost like th what do you think it is?
