This is pretty funny, reminds me of Iwakutsuki Bukken to Yakuro-san by Aneco, except with a female highschooler and a female cursed doll living together in a mansion instead of a male college student and a female earthbound spirit sharing an apartment.
It appears the translators got a little confused with the 2 first panels on page 10 of the first chapter. The doll says "kocchi, kocchi", which means "here, here", to lure the girl to her, but because the lines are written in katakana, my theory is that the translators may have mistaken them for some unknown onomatopeias that they had no idea how to translate them. (I apologize in advance if this sounded mean, but I just thought I'd point it out.)
