As soon as you are out of sight of the shop, you change back to your true-self, the new one, the one in which you are a succubus princess as your wings show.
Your turn back into a Japanese looking demoness, down to your skin color. Your black hairs shorten to a pixie haircut, making you the perfect picture of the sexy Asian tomboy, albeit a version from hell. Strangely for someone of Japan descent, your eyes turn blue, albeit with slited pupils, like a cat. Your fingers/talons change colors until they look like they are made of ice, and so does your cloven hooves. And the spade at the end of your tail? It's turning back in what look like a naginata's blade made of ice.
While you change back, you run without looking were you go, crying. The change you just got through may make you accept your new found girlhood and the same about your demonhood, like if you were born that way, you aren't less affected by how your life got changed, how you stopped being a human boy. If anything it made it worse. And while you are thankful Gwenaëlle didn't take away your tear ducts, like the diabolical ‘mistress’ did to Gwen herself, you also are glad you didn't break down in front of your fellow succubus.
Since you're not looking were you go, you end up running into someone. You don't dare look at said person, but accept their help in making you stand up again. …Not until you notice said person have some sort of old fashioned sandals on their foot. Looking up, you realize said person to be a rather muscular angel, shaped like a Greek god, and wearing a white toga as immaculate as his wings, an old fashioned broom in his left hand while his right one is still in your own. He apparently was cleaning the front of the shop you see just behind before you bumped into him.
Fearing for your life, you start apologizing faster and explain your situation, but this angel simply raise his hand in a placating manner, a reassuring smile on his face. "Don't worry young one, this mall is something of a safe-zone. I won't hurt you, I promise." And on that, gently incite you to go back on your path. But the mall being magic, you end back up in front of his store.
Not having much choice, and since the angel isn't here anymore, you decide to enter. As you do, you notice said angel now being behind the register. "Oh? Hello again, young one! Can't say I expected my humble boutique to be your destination, but please, feel welcome to enter and accept the last steps toward your new life."
You hesitantly walk toward him and shyly ask "How… how does it work exactly?"
"Same as when you changed species. You walk toward the clothes-racks and let your body choose for you. Although… I would start with underwear, and put on them, if I was you. Otherwise it might mess up the rest of your choices. The fitting rooms are on the right at the end of the shop, you can't miss it."
As you browse the female underwear, without thinking on it you end up picking boyshorts and a sport bra. But not seeing why you needed to hide for putting on your newfound underwear, you do it in the middle of the store, prompting the angelic shop-owner to muter something about demons. You feel like your breasts got smaller, but you aren't sure. What you're sure about is how more defined are your muscles, you definitely got stronger and it feel quite empowering.
Now more sure of yourself, you take back your walk around the shop, this time in search of something to wear on top of your underwear. Not that you mind strutting around in your underwear, or even naked for that matter, but you don't want to offend people when it isn't needed.
Alas, all you see is rows and rows of immaculately white togas, nothing you see yourself in everyday. You body seemed to agree. That is until you end up in a part of the shop you didn't see before, where the togas let place to something just as immaculately white, but already more interesting: armors. You couldn't help but think you would only look slightly less out of place in those armors that in the togas, but this time your body didn't agree.
You found yourself with an armful of armor pieces, which were revealed to be far more light than they seemed. You also notice that they aren't all white like you thought, but have a silver flange to it. You see others have gold or black edge instead, but your body choose pieces with a silver rim, and since you were instructed to let your body choose by the nice angel, you decide to keep this one.
Once you're back at the register, you ask him to help you put on your armor. "Before, young one, your armor need a bit of customization. Say, what would you like to have as symbol painted on your chest?" he ask, pointing to the breastplate of said armor.
You think on it for a time, before you finally decide "Maybe some sort of mystical bird… Why not some sort of phoenix, but not made of fire?"
"Not made of fire? Don't think it exist. And what your phoenix would be made of, if not fire?"
You look at your fingers for a bit, all talons looking to be made of ice they have become. "Er… Why not ice? I already have the whole ice theme going on after all." And with that he started painting your "ice-phoenix" on your armor's breastplate. Having nothing better to do, you stay looking at him work, patiently.
Once he finished his magnificent artwork, he help you into your armor. Again you're surprised by how light it is, but also by how flexible it is. As a succubus, you're one of the best contortionist ever and, somehow, this heavy looking armor let you do as you please with your body without the slightest inconvenience.
Then, you slowly gain memories from your new reality, but without forgetting the truth.
