Daten Beach is where the angels went during the summer. They were suppose to help Garterbelt with the church's beach house, but they decided to slack off instead and leave all the work to Brief. The demon sisters showed up and proceeded to state the beach belonged to them. The angels challenged Scanty and Kneesocks to a beach volleyball match in order to determine who would have control of the beach with the losers having to strip naked in front of everyone.
After losing, the demon sisters released an ink bottle onto the ocean, transforming several aquatic animals into ghosts.
