Effects of Body Switching
Members of the Taki family (excluding Konatsu) can switches bodies with their fated partner by touching a certain spot. However they can only remain that way until sunset, any longer then that it is permanent. Konatsu the only member of the Taki family that cannot switch, is also the only person that can un-do Nanao and Kohanamaru’s transformation by simply kissing either partner. This however only affects Nanao and Kohanamaru and not other members of the family. There is another method to un-do the transformations.
Written in a notebook by Kohanamaru’s deceased grandmother is a recipe to un-do the transformations. Ichitaro used the recipe in chapter eleven when Koharu failed to switch with Kojiro before the sun set.
Another effect of the body switching is that a member of the Taki family who switches with someone who is not their destined partner, will eventually lose all memories of that person. Such is the case when Kohanamaru started to forget Nanao or anything related to her. This could probably only happen because of Nanao’s feelings for Konatsu. Though it isn’t impossible to regain their lost memories, as Kohanamaru’s father stated:
“True destiny is thick and strong. So if it’s real, this won’t serve it for good. Let’s watch and see just how strong their destiny is.”
