Heir of Nemesis

*Endymion entered the castle of his enemy, Diamond Black Moon. He found him alone. His younger brother, Sapphiro wasn't there, nor even Rubeus or Esmeraude. Or any guard. This time, it was just him, against King Endymion/Mamoru/Tuxedo Mask, Queen Serenity/Usagi/Sailor Moon, Princess Small Lady/Chibiusa/Sailor Chibimoon/Hotaru and Diana's best friend, the Sailors (Mercury/Ami, Venus/Minako - the leader, Mars/Rei, Jupiter/Makoto, Sailor Saturn/Hotaru - Chibiusa's best friend, Uranus/Haruka, Neptune/Michiru, and Pluto/Setsuna), and the talking guardian cats of the moon, Luna, Artemis and Diana. They had no idea that Diamond had a 17 year old son, or that he was just on the other side of the door, and was about to find Endymion stabbing his father on the shoulder. On the shoulder (by luck, because Diamond was fast enough to dodge it, but not too fast to escape the blade).
