If Letty can do that to Kyouko, I hope that Hijiri doesn't see her. It might inspire Youkai Jesus to take Letty home.
Now I want to see that happen so Big Sis Yuuka comes to the rescue and destroys the restaurant in the process. Minoriko will somehow end up getting hurt, Shizuha will peel a sweet potato, and Komachi will sleep through the whole thing.
