Ranma Half Moon chapter 80 "The First Mysterious Transfer Student Part Five".
Author's note: This episode happens during the Sailor Moon episode 36 "Usagi is Confused! Is Tuxedo Kamen Evil?".
"I am the commander of the Dark Kingdom army. My name is Endymion. You will give that Silver Crystal to me."
Usagi looks crestfallen. How could this be?
VARROOOM. Usagi hears behind her the sound of an engine revving up. Yoma Mitsuami has swapped in a giant electric razor for her forearm. "Time to shave your hair!"
"Yoma Mitsuami, take the Silver Crystal from Sailor Moon."
The monster lunges forward and makes a giant hole in the floor with her razor.
"Yaaaaa!" Sailor Moon runs out of the Salon.
Yoma Mitsuami follows her and smashes a giant hole where the door was. Tuxedo Kamen follows as well.
Minako shakes off the cobwebs from the sleeping gas. Artemis will see this and alert the others, but I have to warn him that Tuxedo Kamen is evil. "Venus Star Power Make Up!"
Minako transforms and races outside to warn Artemis.
Usagi's Sailor Moon and the monster brawl several blocks away, with the Monster knocking down an electrical pole.
"Now I have you, Sailor Moon!" Mitsuami raises her razor.
"Fire Soul!"
"Supreme Thunder!"
The combined attack of Sailor Mars and Sailor Jupiter blows the giant electric razor off of Mitsuami's arm.
"Shabon Spray!"
"Moon Healing Escalation!"
"Wash, Rinse, Refresh!" The Yoma Mitsuami refreshes revealing Kariko Tokoyama and her assistants who collapse asleep.
The five Sailor Scouts face off against Endymion.
Mio looks on angered. This is stupid. He's just been filled with dark energy after being grievously wounded. He's not one hundred percent yet. I have to stop this.
Sailor Mars steps forward. "Mamoru, that's you, right? You've come back?"
Sailor Venus touches Sailor Mars' shoulder. "Sailor Mars, he is not Mamoru, he is Endymion. He was the one controlling that Yoma Monster."
"She is correct."
"But why?"
"Why? Why do you assume that Tuxedo Kamen was once your friend? Maybe my eyes have been opened to who I really am?"
Sailor Moon looks angered. I've had enough! "I don't believe you!"
"That is of no consequence. The only thing that matters is that I will get the Silver Crystal. Even if I have to fight all five of you at once."
Suddenly Endymion hears a loud voice in his head. "Endymion, come back now!"
"Looks like you girls will live to see another day. But, caution, the friendships of girls are fragile." Endymion walks into a black hole and vanishes.
The girls untransform and congratulate Usagi on a good fight.
Usagi nods and then notices something strange. "Guys, that pole is no longer broken."
Minako looks around. "And, the hair styling girls are gone as well."
Artemis nods. "That's the power of the Silver Crystal, the power to undo the damage of Dark Kingdom."
Usagi perks up. "So, it could undo the damage that the Dark Kingdom has done to Tuxedo Kamen?"
"If you can increase your mastery of the Silver Crystal, almost certainly."
The girls walk back to the Kariko Tokoyama Salon. The Salon in perfect condition, with no signs of the brawl that just happened, much to their amazement. And Kariko Tokoyama and her assistants are busy at work.
Minako smiles. The real Kariko Tokoyama looks sensitive and kind, rather than the hard and sleazy woman that I had seen earlier. It's a good thing that the Yoma Monster thought that the steam machine didn't work without making the inference that I was Sailor Venus.
Makoto nudges Rei. "Are you going to be okay?"
Rei smiles. It hurt to learn the truth, but now I could go forward without uncertainty. "Yes. The time for brooding is over."
Makoto smiles. This is the strength that I love in Rei.
...
Ranma-kun hears a knocking on his window. He opens it to let Artemis in.
"He's back, isn't he?"
Artemis looks startled. "How did you find out?"
"I felt a pain in my side like I was being stabbed around six thirty."
Artemis nods. "Yes, that would easily correspond to the battle today."
"Battle, was he hurt?"
"Ranma, the Dark Kingdom has brainwashed Mamoru. They convinced him that he is the commander of the Dark Kingdom army and trying to get the Silver Crystal."
"That's monstrous!"
"Is it? Was Tuxedo Kamen really on our side? He claims that he has awakened to his true self."
"Stupidity. Why did the Rainbow Crystals choose him over me?"
Artemis nods. "Good point. Hopefully, the power of the Silver Crystal will be able to bring him back."
"I can do it. I have used the wand before. And, I am linked to Mamoru. I can bring Mamoru back."
"We should let the other Sailor Moon try first. She still needs to become more in sync with the crystal. If you take the crystal from her, it might crush her confidence."
Ranma-kun nods. "Okay, for now. But, this other girl had better get some results or I will be bound by the warrior's code to try to save Mamoru myself."
"I understand."
"Oh, some weird news. Guess who became a transfer student at my school today? Tenou Haruka. Sailor Uranus."
"That sounds like good news."
"Maybe, she says that Sailor Neptune believes that their enemy is going to make a move on the school."
"Are you okay with this?"
"Haruka is a lot of fun and she seams to have won over the whole school in the first ten minutes that she was there."
"I'm sure she has, but if she's hanging out with Michiru, don't you think that things could get messy? You two don't see eye to eye."
"Yes, she is a loose cannon. But, if there's a second enemy out there, she might be our only way to identify it."
"Looks like you have a lot on your plate after all."
"Indeed."
"Then you'll need this." Artemis does a back flip and a crescent wand appears. "This wand is similar to the one the other Sailor Moon uses. "If Dark Kingdom moves on your school, it's possible that they would use your classmates as Yoma Monsters. This can help you turn them back."
Ranma-kun nods. "It's missing the crystal."
"The wand works without the crystal, it's only less powerful. However, this is your chance to show your skill level."
Ranma-kun takes the wand with an air of seriousness. "Okay."
Next up! A second transfer student?
