PRELUDE

Chapter

One

The group stood crowded in front of a rather normal-looking building that was located on a secluded plot of land outside of the West City perimeter. It was a plain thing, not much decor, barely any colour compared to all the other buildings and houses in the city.

Then again the person they were looking for doesn't like attention being drawn to them, so a plain capsule house was to be expected.

The person they were looking for was also the reason for their hesitance to knock on the door. For they were very powerful, Whis would call that an understatement, they could kill a deity with a thought, though that is only if the deity in question has severely wronged them. Or they hold some form of importance to the continued function of the cosmos, and nothing can be done about the inconsequential mortal desire for vindication.

The current Destroyer G.O.D of Universe 7, Beerus, thought of how they came to be in this predicament and why they were seeking this particular individual out.

An hour earlier

~•~•~

Returning to The Supreme Kai's realm the loud boastful human with the afro, named 'Mr. Satan', started talking to the motormouth moronic Saiyan that got us dragged into this mess in the first place.

"Hey Goku, you can win this thing, right?" The human was probably sweating more than Lord Beerus was himself with how shaken he was from the Expo.

"I can't know for sure…" Goku said before brightening up from his prior seriousness, "But with Gohan and Buu on the team I sure do like our chances!"

That seemed to make the pitiful human brighten up, his non-existent confidence seeming to reappear with the Saiyan's fighting spirit. "Yeah! I forgot all about Buu!" Mr Satan said turning to glomp his gumball friend "You gonna save the Universe Buddy?"

"I'll try to come up with a battle strategy for our team—" Goku cuts over his son Gohan with a grin and his hands comfortably behind his head.

"Okay but I think we'll be fine though."

Beerus growled low in his throat at the Saiyan's continued arrogance and nonchalant attitude towards the literal universe annihilating tournament. "I literally just told you to start taking this tournament seriously!!"

Goku frowned at the God of Destruction dropping his hands from his head. "I just have to win, geez, I get it." He said with a whiny tone.

The GOD's eye twitched and his face morphed into a patronising sarcastic expression. "Yes, obviously Goku. The question is what's the actual plan for pulling it off?!!"

"How can we plan when we don't know who we're fighting?" Goku said once again, folding his hands behind his head, "There's no use worrying about what we can't control."

"Shouldn't you at least use this time to train?!" Beerus returned with an enraged glare.

Goku huffed rolling his eyes "Getting riled up all the time can't be good for Ya—"

Finally, his attendant decided he'd had enough of their immature squabbling and cut over the top of the Saiyan.

"Alright, you two, that's quite enough bickering. You should be using this time to form the rest of your team." Whis said, thoroughly annoyed and feeling a bit petty he added: "You just have two days to recruit seven more fighters, I'd start asking around if I were you."

"Hah." Beerus scoffed, eyeing his attendant critically, "I can tell you're loving this. Even if we lose you still get to stick around."

"Ohohoho!" Whis laughed. "Guilty as charged." He admitted unashamedly. "It is the advantage of being a mere guide dispatched from the great beyond, My Lord." Eyes glinting with mirth.

"You go from faithful Angel attendant to a mere guide based solely on what's convenient." He said with a sneer.

Beerus suddenly perked up and turned back to Whis, his yellow eyes glinted with devious intentions and a sly grin grew on his face.

"Come to think of it Whis… The Grand Minister to Zeno is your father, am I right?" He questioned his Angel attendant.

Whis squinted his eyes at the purple bipedal cat, giving a slow and wary confirmation.

"Yes My Lord that's true…" the Angel was interrupted by the Elder of the Supreme Kai.

"Whining and taking shots at each other isn't what'll win us that tournament boys." Elder Kai reprimanded.

"Give daddy whatever he wants so he'll exclude us from the tournament of power!" Beerus ignored him, continuing to whinge at Whis who now had an eye twitch.

"With all due respect; I will do no such thing." started Whis with a glare aimed at the Destroyer "You're a GOD Lord Beerus. You should act far more dignified—" before the pastel blue angel could finish; the younger of the Supreme Kai, Shin, cut him off.

"I apologise for interrupting you, but I believe I may have a solution." He said drawing the attention of the other mortal guests to the Sacred Realm of the Kai. "There is perhaps one being in all of the cosmos, aside from the Omni Kings and the Grand Minster himself, who is capable of helping us."

"I've only met them once. Though I'm sure you remember her well Elder Kai." Shin said with a tiny but no less malicious smirk on his usually friendly face aimed at said Supreme Kai.

"Tall, black hair, beautiful green eyes, short temper, really doesn't like you ~ …" Shin listed off purposely dragging out the last sentence leaving Elder Kai, who looked ready to keel over, to frantically proceed to cut whatever else Shin was about to say off; shaking his head wildly, losing all of his previous collectedness and paling drastically.

"Nononono! No! Please is there not anyone else? Anyone at all?" Elder Kai begged with his eyes wide with unmistakable fear as he looked about the group pleadingly his lavender skin was now bone white.

"And who might I ask is this person you speak of Kai?" Beerus asked with a raised eyebrow folding his arms across his chest. Shin smirked at Beerus smugly before he turned his attention to Whis, the angel had leaned forward in slight interest in the subject.

"I can only assume that you would know her personally, Whis, I would say that she is the best chance we have. All Elder Kai here needs to do is apologise, to regain her favour." Shin said as he pats Elder Kai on the back who whimpered feebly.

"Apologise to who? Who are you talking about Shin?" Gohan asked, joining in the conversation with his glasses firmly back on his face.

"Why the Mistress of Death of course." He replied nonchalantly whilst enjoying both Whis and Beerus' shocked expressions from Beerus' gaping jaw to Whis' genuine gasp of surprise.

"You know the Mistress of Death? And have already offended her magnificence?" Beerus forced out through clenched teeth, glaring at Elder Kai, who shrank back attempting to hide behind Kibito who simply stepped away so he too could glare at the Elder Kai.

"Who's that?" Buu asked surprising his present company with his sudden inquiry, his arms crossed over his chest, his brows furrowed over his squinted eyes as he tried to remember if he heard the name before, 'it sounds familiar to Buu. But Buu not know where Buu heard it before.' The magical blob thought to himself as Whis once again had to explain things to them.

"The Mistress of Death. Long ago was once just as mortal as all of you are now." Whis began, "Though that has since changed and currently speaking she is a nigh-omnipotent immortal being capable of incredible feats, one that cannot be rivalled by just anyone.

"Although when feeling especially bored the Mistress of Death habitually suppresses her immortal capabilities to lessen her eternal boredom and loneliness fighting mortals. Making the fight as fair as mortally possible, and so she won't accidentally destroy a galaxy or another universe…" Whis explained before getting slightly sidetracked.

"Oh, and I've heard she's a marvellous cook, though I have yet to try any of her culinary goods myself..." Not so uncharacteristically Whis' mouth began to water as he recalled the first time some of her food had been mentioned in a conversation with his sister Vados before he noticed the annoyed looks from the others and quickly continued.

"Eheh, as I was saying;" Whis coughed into his fist hiding his small smile.

"She came from a planet that coincidentally was also called Earth. It died a long time ago none too dissimilar to Universe six's Earth: thrown into a foolish war for world domination.

"Her universe was erased from existence due to the actions of an out-of-control destroyer. She was the sole survivor of that universe no thanks to some otherworldly power, – one can only assume was – divine intervention and has since developed a close kinship with Zeno as she gained a hold of her new life as an immortal… of course, this was much before angels attended the G.O.Ds so personally." He showed them images of the MoD's home universe before it was destroyed with his staff.

Whis frowned lightly when a thought struck him and he changed the view to that of the woman previously described by Shin. Whis had never gotten to meet the MoD herself, though he wished to and so using his mystical staff began a search for where she could be hiding. Images zoomed by at indiscernible speeds before stopping on one very dull image of what looked to be an earthly residence. A frown weighed upon his brow before smoothing out into a very intrigued and slightly amused facial expression which all who witnessed it noticed.

"Interestingly enough, she has chosen to make herself at home right here in Universe 7 on your planet earth..." Whis finished with a fond smile while Beerus glared mulishly at the ground having never met the Master of Death because he was asleep, and his brother more than likely had, but cheered up when Whis mentioned the Mistress of Death had chosen his Universe to call home.

"Ohohoho. It seems she also chose to reside in universe 7's earth because for whatever reason Champa had offended her and lost her favour." Whis finished with a small smile.

Everyone, even Buu, gaped at the attendant before simultaneously turning to face the one who'd offended her within their midst, furious glares on the Elder Kai.

Then Mr Satan short circuits for a second and butts in. "She's on Earth?!" He semi yelled his eyes wide in fear and awe.

Similar expressions could be seen in the others as the realisation hits them, minus Buu(he was still wondering where he knows the MOD), as well and they looked to Shin eager for more information on the mysterious Mistress of Death, and her whereabouts.

"It would seem so. Though I doubt she will accept many visitors. I can take us to her current residence. Elder Kai will need to apologise before we can ask anything of her." Shin explained, holding his hands behind his back awaiting their decision. It didn't take very long for them to make up their minds and Elder Kai was suddenly held by his upper arms being carried between a resolute Gohan and Beerus.

Whis clapped his hands in delight grasping Goku, who was closest to him, shoulder and Goku grabbed Beerus's The Elder Kai was between him and Gohan, Mr Satan held his other while Buu was between him and Shin, and Kibito stayed behind. The Supreme Kaioshin looked around with a smile before saying "Kai, Kai." and they were gone.
