http://www.mangago.me/read-manga/daughter_of_the_emperor/ - Reincarnation Shoujo, I personally like this one most.
Goddess creation system. - girl transported into historical era with game function and has to win the hearts of characters to earn points and go home. Mc make men fall in love with her but shes cunning and only doing to for the points.
Potion tanomi de ikinobimasu. - very smart cunning woman reborns as a 15 y/o girl in another world which cheat skills. She uses her powers and cunning to steal, scam and screw around basically.
The white cat that swore vengance was just lazing on the dragon king's lap. - girl is summoned with buddies. She's the "saint" but everyone else is dumb and they mistake her friend for the saint and kick her out to die. She's a good kid.
Isekai de "kuro no iyashi te" tte yobarete Imasu. - girl transmigrates into a new world where magic is possible. She has HELLA magical powers to the point she can just make stuff up and it becomes a working spell. Kinda intense. Somebody'/ arm gets chopped off. Mc similar to white cat i think.
Otome Game no Hametsu Flag shika nai Akuyaku Reijou ni Tensei shite shimatta. - girl is reborn as a otome game villianess. She just wants to avoid her bad ends and live a happy life but gets a harem anyways. Mc is oblivious.
Seijo no Maryoku wa Bannou desu - also a saint with potion powers, who happens to to be summoned with another girl that people assume is the saint. Mc has ability to make potions that are 1.5x stronger. Good romantic progression and a little more adult like.
