Seeing the strange purple creature got Mako into a huff. She was so angry that she barely had time to register Rei running out of the room, or the black cat watching from the windowsill. With everyone else out for the count, the Brunette decided to take matters into her own hands.
With nothing but sheer determination, Mako charged at the creature, picking it up and lifting it over her head. "I came here to have a good time with a friend." She was so focused that she didn't notice Sailor Mars enter through another door, or the cat having a shocked reaction to something (namely, the girl having the alchemist's symbol for Jupiter appear on her forehead). "I'm not going to let you get off without payback.", Mako continued, throwing the creature at the wall. Before the creature could strike back, a voice rang out from behind them.
"Mars Fire Soul, Ignite!"
A burst of flame flew through the air, hitting the creature. Makoto turned to see a black-haired girl, about her age, dressed in a female styled sailor suit. But then the black cat she had looked past earlier. It had a green pen at its feet. But that wasn't the strangest part. That would be when the cat spoke to her.
"Makoto Kino, you are one of the chosen warriors to defend Earth from the Dark Forces. You are Jupiter, the warrior of Thunder and Courage. Now take up this pen and fulfill your destiny."
With these words, the girl picked up the pen and held it up to the light. She yelled "Jupiter Power, Make Up!" Thunder shot out from the small rod, surrounding her. In a few seconds, she was dressed in a similar costume to Sailor Mars, but with the red areas coloured green.
The appearance of the other Senshi warrior startled the creature. It watched as the newcomer sprouted a lightning rod from her tiara. Then the new enemy launched into a speech "On behalf of Jupiter, I call upon the power of thunder and Lightning to vanquish this evil." And then the attack began "Jupiter Supreme Thunder!" The attack caused severe pain to the creature, enough that its preservation instincts told it to flee.
The Youma made it over halfway out before it stopped. It realised that the two Senshi weren't following it out. They must have stayed behind to try and return the stolen energy. Typical sentimental humans. The loss of their hard-gained energy didn't concern the creature. As long as it could pin this on the two interlopers, it would remain alive.
It was then that the Youma noticed the other man. He was dressed in a dinner suit, a top hat and a full face helmet. He was obviously human, the creature could sense that much. He pulled a rose out of his pocket, and threw it. The Youma screamed as its heart was pierced. And then it knew no more.
Elsewhere, Jadeite felt something. His servant, Bakuril had been eliminated. That meant that the same interloper had struck again. That, or someone else had found out about the Dark Kingdom and taken his servant out. Regardless, he needed to take action to ensure there was no more interference. He'd had enough of that from Kunzite and was guessing that Zoisite would be encroaching in on him soon. He needed a warrior that could stop the mysterious Senshi before she could attack. And he had just the person for the job.
