What am I doing, you might ask? I have absolutely no idea!

So basically, here's the plan.

In this world, there are magical girls, or as we call them... yeah I need to think of a cool name let's just call them magical girls for now. To hide from the world while they fight ambiguous monsters, they project timespace manipulating barriers that allow people to pass through as if nothing happened.

Our male lead is a regular dude guy who somehow managed to enter one of these barriers (specifically one made by my character) and is shocked to see the sights. Also he accidentally kisses my character and that was when he discovered his other weirdass ability - he can fuse with magical girls to make them bigger stronger magical girls.

Now, you might ask about elements beyond what I've presented, elements beyond the excuse to make this a harem, elements beyond being a magical girl gig.

Where do the obligatory monsters of the week come from? How do magical girls become magical girls? Is there some kind of hierarchy or society for magical girls?

Good question.

So, basically, the roles present will be:

Male lead
Female lead (yours truly)
Various other magical girls
Obligatory mascot/s
