Since his break-up with Usagi, Mamoru hasn't been the same.

*A couple days later*

"I wonder if she even misses me" Mamoru said to himself while sighing heavily. His best-friend was worried about him, but Mamoru paid no heed to Motoki-kun. It was as if he was in a trance; nevertheless, Motoki walked up to him.

"Mamoru-san, are you alright? Is something weighing heavily on your mind? Would you like me to call Usagi-chan to brighten your day?

Mamoru was still lost in thought, so Motoki's question did not register in his mind at all. Motoki began to grow impatient and waved his hand in Mamoru's face, but it did nothing. After everything he attempted, Motoki-kun gave up trying to have his friend acknowledge him. Unfortunately because Mamoru was zoning out he did not see a certain person walk into the Game Center, heading straight towards him.

"MAMORU YOU POMPOUS, ROCK-HEADED, BUTTER-NUT EATING TWO FACED CHEAT!" Someone yelled right into his ear.

Mamoru looked up and saw Rei-chan, Usagi's friend, who was also known as Sailor Mars.

"What the hell do you of all people want?" Mamoru questioned as Rei glared at him with fired eyes.

"I want to know why you broke Usagi-chan's heart, Mamoru!" She cried in a desperate attempt to reveal the reason he had. Motoki heard this and his mouth dropped agape.

He thought his best-friend and fiancé were doing well. Yet, instead they were broken up. Usagi is most likely in tears. I know she loved him more than anything. It's a shame.

"I'm engaged to another woman. It appears Usagi was not my true destiny as we all had previously thought", Mamoru said as he clenched his fist and jaw, and he pretended as if it was not bothering him.

"Did you forget that you two are DESTINED to be together? What about Chibi-usa, and the throne of Crystal Tokyo? Endymion, she died for you several times in order for you to love one another in peace. Do you not understand why she is in so much pain right now?

"I died several times as well. I honestly believed we would be together until the very end, but it seems as though we were not meant to be. She deserves better than what I could have offered Princess Serenity. You know as well as I that with the Negaverse not fully destroyed, they could come back and harm Serenity when and if they pleased to. I'm sorry". Mamoru had tears in his eyes, but he had to hold them back to not let on about his true feelings.

Rei had tears streaming her face. She could not believe what this ass-wipe was saying to her. How could she allow this to happen to her beloved Princess Serenity? She was supposed to protect her!

"Will you at least imply who you are engaged to? Does Usagi not deserve that much from you?" Rei asked again, but with her anger more noticeable.

"I can't... I'm sorry," He replied softly. He gets ready to leave and just as he is about to walk out the door Rei-chan grabbed his shoulder.

"Hold it! Don't you think she's been through enough pain between the Silver Millennium and now? How can you be so cruel Mamoru? I thought you promised to love her and keep her safe?" Rei questioned with anger in her eyes, but before Mamoru could answer someone knocked him out. Horrified she looked up to see two smiling faces, and two glaring ones.

"You… Why are you here?" She said in a hushed tone.

"We heard about a little trouble the Sailor Senshi was enduring. We wanted to be of assistance once more to our beloved friends we made here on planet Earth. Is that not alright, Rei-chan, or should I say Sailor Mars?" A familiar person answered back.

"Shhh! Let's talk somewhere else. We have to get out of here before the manager comes back and notices Mamoru is unconscious," she quickly said back.

As the group left with an unconscious Mamoru-chiba, they had forgotten they were in the presence of Motoki. He heard bits of the long conversation between Rei-chan and Mamoru-san.

What did they mean by Sailor Mars, and why did Rei-chan call Mamoru Endymion? What is going on in Tokyo, Japan?
