“I am the Lunar Guardian, protector of Love and Justice! In the name of the Moon, I will punish you!”  
“The Rose Knight, defender of Earth. In aid of the moon, I will punish you__!”
 
While frequently butting heads in their youth in their civilian forms, a romance budded when they met in their transformed states with a disguised Ensemble assisting the new Lunar Guardian in protecting Neighpon and leading her team. Their predecessors were amused and let the secret stay, but eventually Mariner “Meatball Head” Moon recognized her crush despite the get-up; much to Ensemble’s embarrassment. But, the blossoming grew and they eventually married with a daughter, Mariner Chi Bi “Chibi” Moon born a few years later.
 
Recently however, something has started to go wrong with Serena’s powers and mother’s intuition tells her their daughter is going to be so grounded soon…
