Imaginator!

Hinata, a Heisei gal, dies from an incurable illness. When she is reincarnated, it is into a fantasy world where imagination literally becomes magic—known as imagical. While renowned imaginaters (magical artists) are being reborn into this world, Hinata is just an ordinary girl who loves handicrafts... Deemed useless and unfit for the task of protecting people from monsters, she's cast aside. Even so, with her trademark positive attitude, Hinata decides to go out into town to buy some cute clothes, only to find that not a single stylish outfit exists! This is a world with zero interest in "art" or fashion! However, a chance encounter between this outrageous gal and a cynical artist sets the stage for a bold new stroke of color across the world... A remake fantasy where a wild gal and jaded artists transform a world with zero imagination!
