It was late at night, you were walking around the Butterfly Mansion. You then spot Tengen and Giyuu up ahead, talking to Rengoku and Shinobu.

Giyuu: "I wonder why we all cannot sleep." Shinobu: "Yes, I do too!" Rengoku: "Yes, why are we all not peacefully sleeping?" Tengen: "Allow me to wonder that as well, why are we all awake at this hour?"
