kurosaki is a copy witch.
well this week revealed that he might be a witch. he kissed arisugawa and was transported back to her past. if he was a copier, that would mean arisugawa had the power.
but it would make sense if he was a copier. that would mean arisugawa's power is to travel to the past of whomever she kisses.
BUT kuro having the power instead would still be plausible in this scenario, even though witch powers either affect the kissed or both the witch and the kissed.
