Love Potion That Spread Through Kissing

Have you heard of love potion that spread through kissing? Well, I have not heard of that method of spreading. In that episode 6 of Zero No Tsukaima Season 3, it happens. Siesta has receive a unknown love potion from her friend (forget the name) that is taken from a customer without knowing the details of the potion.

The sad thing about that is that even before Siesta get to use the potion, she drop the potion down to Montmorency who open it up and breath in the medicine. that potion seems to build the person forget about all

the hate and love everyone they sees.

However, that potion will not only effect the person who breath in it. It will plus spread through the action of kissing.

This episode has actually only show one method to stop the effect of that potion. It is to assemble the person forget about the things they do for that period of duration which will additionally form them forget the kissing which is the main cause of the situation.

If there is something for you to choose that can be spread by kissing, what will you choose?
