Ok, this is just a silly question but if you were to write a magical girl with D.I.D how would you do it, would the powers be tied to the body or each alter, since your gf told me you are working on a relevant story?
i am in fact working on a relevant story! i'm a self-published author, and i'm currently planning out and developing a trilogy about this exact concept. current working title is "Help! My Alter is a Magical Girl!" and i'm hoping to release the first book at some point in the back half of 2027, though this is of course subject to change. you're never going to believe this, but it is about... well, someone with a magical girl alter. the way it works in this specific universe is that every magical girl has a "theme" for their powers. so for example, let's say someone had gemstone theming. all of her abilities would be focused around jewels, and all of her alters would be named after various gemstones (ruby, sapphire, emerald, etc). and while they might all have various individual abilities, they're all presented through the overall theme of these jewels. one alter might be able to create fire, another can another make plants grow, or another could another cast strong winds, and so on, but it all comes back to various gems they have or can summon as part of their magical girl abilities. i hope this makes sense? the alters have individual abilities but are united by a common theme and a common way these abilities present. more information about this series is coming as i develop it more, and when i finally publish it, i will be posting about it. so keep your eyes out for that within the next year and a half or so if that sounds interesting to you!
