You think back to your life. You liked being a boy, a lot actually. You liked your friends, you liked your family, but something about this world was just intoxicating! Everything was clean, even posessing Akko's body you just felt happier. Heck, if Aisuru is to be believed everyone was functionally immortal here. It would be a shame to force a wonderful world like this to be sealed off just because you were scared of becoming a girl.
"I'll help make my world a better place, thank you for giving me this opportunity."
Her smile grew, and her eyes finally closed, "I was hoping you would take my offer, I know we may have started off on the wrong foot but I truly do just wish to foster a world where girls can love each other in peace, and if you truly do share my goal, I hope we can spread the love throught your world as well!" She beckons for you to sit down at the dining room table and summons a chalk board, beginning to draw some diagrams. "So once again, you will need to say your true name, attempt to possess me with the mirror then our souls will begin to bond, this will allow me to reshape your soul and get a better look at the magical structure of your world. How does that sound?"
"Great!" You respond. "Will I gain any special powers to help me purify my world?"
"That's the thing, all magic must transfer through the fabric of reality to do anything, if your world's fabric is thin, like in this world, it would be pretty basic to reshape things, but if magic is as rare as it seems to be in your world, that could mean one of two things. One, the fabric is relatively thick, preventing me from doing much. Two, it is thinner, but arcane knowledge is being actively surpressed by some group. Clearly you have no arcane aptitude so I'd have to be the one to check what my power can do. Well, no time like the present, I have dispelled the wards, I want you to head back to your world then possess me as soon as you can, we have no idea how our timestreams interact after all!
Despite the uncertainty, you say your true name "Sean Conners" and feel pulled out of Akko's body.
Back in your room, you quickly picture the love goddess you just talked to. "Aisuru the love goddess" you say, and her jogger form appears on the mirror, despite popping a boner from the visible cleavage, you quickly jump back in.
Unlike all of your previous possessions, you didn't feel like you were in a body anymore you could see a whole town stretching out in front of you, and suddenly you felt yourself stumble, not your body, something greater. You think to yourself "That mirror was stronger than I thought, but I still have control." Wait, no you didn't! Was this Aisuru's thoughts? "Yes, and thankfully this masculinity is not as deep rooted as I first thought." You wonder if that means Akko will be okay. "Nothing a shopping spree with her friends couldn't fix thankfully, I conjured a coupon book for the dress boutique and her soul is already shining as bright as ever." "Now then, its time to purge away that nasty masculinity" You start to feel weird, even when possessing girls before you always thought of yourself as a guy, you were kind of aggressive, and wanted to be in charge. You really liked thinking about the Ro-
You just lost your train of thought
What were you thinking about before?
Was this purge causing you to lose your memories?
"No, but it will make your interests more healthy, instead of thinking about wars and - " a shudder ran through your entire form "Men in armor"
You now wanna buy stuffed animals and have tea with cute girls!
"Now you're catching on! Compared to that vagabond Taiga, you don't seem that attatched to being masculine, its like scrubbing a bunch of moss off a boat instead of prying off one barnacle."
You wonder if thats why Akko ended up fine
"No, its because the mirror tries to consume the soul of the target instead of merging with it. If it merged with the target you'd change a little bit every time you possessed someone."
You feel strangely afraid to ask how magical your world is, but find the bravery to ask anyway
"I have no idea, I'll have to follow your soul there to see. Oh speaking of which, you have a new true name, I'm sure you know what it now"
You smile, and say the name of the new you
"Kamiko Conners"
Unlike the previous times you returned to your origional body, you felt gangly and gross. Your package felt more like a tumor than a source of pride. You hear a voice coming from your right.
"Interesting! Veeeeeery interesting!" A tiny version of Aisuru with angel wings was floating above your shoulder.
"This world's fabric is..."
