Storyline: Usagi is tired of the things Mamoru has put her through. When she finds him with another girl, she slaps him. Then he breaks up with her again and she goes to his apartment to apologize and plead with him. He refuses to get back together and Usagi, heartbroken and thinking of Chibi-Usa, leaves in tears. Later, during a fight with the senshi, Usagi is transported to the Dark Kingdom, where she finds Mamoru swearing allegiance to the enemy. Heartbroken, she finally kills him after a short battle. This is truly the end.
Creator's Notes: Don't bother to comment about how Usagi and Mamoru are the best together and how Mamoru would never do that and yadda yadda yadda. I will laugh and probably delete your comments. I don't like this pairing - never have, never will. I like UsagixSeiya instead.
