[Forgotten Promise?] Where is our flying Sleipnir?

[Magic-Mal]

When flying, she wears a purple aura, full of treacherous appearance!

Sleipnir is a girl horse? O__o
Is that an error?

I am curious why it has not been able to fly yet as well.

People say the excuse "Because it is optional mount for extra cash" but in FF games Sleipnir has always been able to fly even in the mythos that Sleipnir is based on.

Well the fact it's an optional mount you pay is an excuse to give it the flying ability. You pay it, so you should get everything it can get.

most likely, Slepnir is a stallion born by Loki who at the time was a female horse. (norse mythology is odd but cool)

Saw a jp dev blog and Sleipnir will fly in 4.1, and witch brooms will have a sparkle ability.

If Ixion horse mount can fly why didn't they make Sleipnir mount able to fly the same time. They would both fly the same way since there so close to one another.

It will fly in 4.1 everyone rejoice!

now we just need the goobbue to fly with his wiggaly arms (or sylphs carrying them and them just scratching there butt chewing crud) and the requests will be complete ;w;

That's just google trying its best to translate Japanese. I didn't read the whole page, but the actual line in question,

お待たせしました！
マウント「スレイプニル」が大空を舞う！ フライングマウント化、ついに対応です！

飛行時は紫色のオーラ（？）をまとい、禍々しさいっぱいの姿！

There's no mention of gender. Japanese people don't usually refer to people as "he" or "she", which is why it's a lot easier to have characters of ambiguous gender in Japanese anime but the English dubs usually struggle and just more or less assign a gender to them (but maybe have it be challenged at some point in the series).

FYI stallions are intact male horses lol
