SailorStar9: Another fic coming from me after being inspired by Faerie of Lightwater Forest's 'The REAL Reason Why Pluto is No Longer a Planet' fic. So, thank you, Faerie of Lightwater Forest for giving me this brainwave. So, read and review.

Summary: 'Arranged marriage' are two words one does not associate with Kai Chen. So when his parents drop the bombshell of his imminent marriage, he uses his deployment to Terra Venture as an excuse to escape his pending marriage. Little did he know, his bride-to-be is also on board the space colony.

Five years ago, Mizuno Ami left Japan after the Senshi railed against her for refusing to summon the 'Gates of the Underworld' in battle; a summoning the Senshi saw as an easy and convenient way to rid them of their enemies. Five years later, the renamed Amy Anderson, boards Terra Venture as one of its medical personnel.

Prologue: The 'Gates of the Underworld'

"It's beautiful, isn't it?" Dr. Phil asked, seeing his assistant and best student look out of a window into the inky space.

"Yes, sensei." Amy Anderson nodded.

"I'm no longer your sensei, Amy," Dr. Phil chided. "We share the same title now. Do you regret leaving?"

"After what happened five years ago," Amy turned to her once lecturer. "No."

Flashback

"Do you know why all of your battles so far have been so difficult?" a dying Jadeite taunted, Super Sailor Mars' 'Flame Sniper' having dealt the Shitennou the final blow. "It's because Sailor Mercury didn't summon the 'Gates of the Underworld'. If she had, all your enemies would've been sucked into the Underworld, never to return."

"Sailor Mercury doesn't have such a spell." Super Sailor Jupiter defended. "Even if she did have, she would've used it against all our enemies, right?"

"I'm sorry, Jupiter." The ice Senshi whispered.

The Inner Senshi were shocked, but the shock turned to rage and hurt.

"Then why didn't you use it?" Super Sailor Mars snapped.

"We won't have to die." Super Sailor Venus pointed out in pure resentment. "Why?"

"You've disappointed me, Sailor Mercury." Eternal Sailor Moon hissed, looking at the Senshi in pure hatred after the others railed against her for not using such an effortless way to get rid of their enemies.

Turning to the smug Jadeite, the Ice Senshi realized that the dying Shitennou had achieved his goal of turning the Senshi against her and that realization was more than enough to break the restrictions the water Senshi placed on herself on her full abilities.

"Aeon Mercury Power!" Super Sailor Mercury's ice-cold voice rang out, her Super form replaced by her 'Aeon' suit.

Jadeite's eyes widened in in horror when the Aeon-level Senshi raised her Caduceus.

"Gates of the Underworld, I summon you," Hermes' daughter chanted the summoning spell. "As the daughter of the Conductor of Souls, to appear before me!"

"I hear your call and respond, Princess Amity, daughter of Hermes." A low drone sounded from the massive gates. "Evil soul that has tormented my Lady thus far," the statement was directed at Jadeite. "There is a specific place for you in the Fields of Punishment."

The other Senshi gaped in astonishment as the towering Gates pulled Jadeite into the inky darkness using two Hell Chains before shutting close.

"Don't even move!" the Aeon-level Senshi growled, her weapon now pointed at the astounded Senshi. "You wanted to see my full power; I gave you that. Just so you know, Sailor Moon, the Gates of the Underworld are not a vacuum cleaner to suck the enemy in, nor are they supposed to be used to make your job easier! You ask me why I didn't summon the 'Gates of the Underworld'? Then why don't you ask why Sailor Pluto doesn't let Sailor Moon travel back in time whenever she fails a test so that she can retake it until she passes?"

"Because…" the silent Sailor Venus muttered.

"It's taboo for me to do so." Sailor Pluto finished the sentence, the Outer Senshi had arrived at this point. "Let me guess," the Time Senshi looked at the group of warring Inner Senshi. "The girls wanted to know why you refuse to summon the 'Gates of the Underworld'?" she looked at the daughter of Hermes.

"Pluto," Eternal Sailor Moon asked meekly. "You know the reason?"

"It's because it's only meant to be used as a 'no choice, last resort' kind of spell and not a convenient way to get rid of our enemies." Sailor Pluto sighed. "Now that Amity has regained her full memories and complete powers, she no longer answers to you, Princess Serenity; her allegiance now lies with the Olympian Council. In short, she's a free agent now."

"If there's nothing else, I'm leaving." Aeon Sailor Mercury remarked, her transformation reversing as she walked off.

The next day, the girls had tried to find Ami to apologize, but found the Mizuno apartment empty.

It was not until Monday that the school principal announced that Mizuno Saeko had withdrawn Ami from school as the elder Mizuno had received a job opening in America and had taken her daughter along with her.
