She was a scientist, reborn as the former hero and the Queen of Spirit child. She is an elements spirit (as in science elements), set on defending her family against their ennemis! Overly loving family to the point it is funny. Mc is smart and OP. Overall interesting base, funny and cute story, nice art, but cliché villain... which makes the plot a bit cliché...
Dad is a Hero, Mom is a Spirit, I'm a Reincarnator
