The cult leader Dimple shows up, making everyone laugh and explains that he wants to make everything laugh and happy. He makes one of the people on the scene put on a mask.

But as Dimple removes the man's mask, he starts laughing, making Ichi wonder how is that possible. Ichi wants to leave, but Dimple doesn't let her go and puts a mask on her, making her start smiling and laughing.
