Haven't watched Magical Girl Ore fully (only ep 1), but I happened to pass by the anime by searching a Japanese Translation for "Me as a Magical Girl", which involved Magical Girl Ore in the top recommendations (I don't know the terms).
It's pretty funny how they show realism that despite females can match males, the idea of body composition with the two genders were given differences. As like in Madoka Magica, females are more likely to feel emotions than male, giving them an upper place when the power relies on emotions!-- But!
The concept of Magical Girl Ore was to find a person with strong emotional personality (which are females) but is physically strong to match or synchronize both aspects to be compared as strong enough, which lead to the conclusion of having girls contract as Magical Girls but changing them biologically into male while in the Magical Girl Ore forms.
And funny thing!
Despite the homosexual display of some of the characters in the show (which I find it cringey...), the former magical girls (or should I say... at least one... as what the anime showed) explained that their husbands were attracted to them because of their Magical Girl Ore form! Giving a hint that their husbands were ONCE gays, and became bisexual after the revelation!
AHAHAHAHA!!!
[Which also raises a flag that, Saki and Mohiro would likely end up with each other!!!]
