Chapter 3. Serenity Fully Awakens

After returning to their home Papyrus called both Alphys and Undyne along with Toriel and Asgore to have a meeting at the house. For Luna to explain everything to them.

The four monsters follow closely behind the tall skeleton up the stairs. Towards to what use to be his old bedroom but had. Became both Serena's and Mina's room once they both moved in. Having Papyrus share a room with his older brother.

" Okay, Furball," Sans added as he opens his eyes and looks towards Luna while the five monsters enter the room and shuts the door behind them.

" Ya' have a lot of explainin' ta' do." he continues while side glancing towards the passed out pigtail girl who was now Serena.

"... A long time ago ...perhaps before the monsters were forced. Into the Underground. There was a beautiful Kingdom on the moon. Ruled by the kind Queen Serenity. The Queen was loved by all in the galaxy including the people and monsters of Earth. For she had protected their home and them with her powers when needed. Serenity had a beautiful daughter...name Princess Serenity. So she had assigned the young princess her guardians. Who would also be her royal court and those protectors were. Sailor Venus Princess of Venus, Sailor Mars Princess of Mars, Sailor Mercury Princess of Mercury, and finally Sailor Jupiter Princess of Jupiter. Together they would protect the young Princess in the Moon Palace. Yet young Serenity was curious about another planet..Earth . There she had met the Prince of that beautiful planet. And they had fallen in love having another woman name Beryl to become jealous. Out of jealousy, she had given her soul to a dark force. That was when she had brainwashed the Earth's people and ordered them to attack the Moon Kingdom. The young Prince was killed in protecting his Princess. Heartbroken Princess Serenity took the Moon sword and use it to end her own life. After the finding, the body of her daughter Queen Serenity was in despair. And yet she knew how to fix this with the last of her strength the Moon Queen used the Silver Crystal to lock the darkness away along with trapping the Princess and the others inside. She then ordered Artemis and I to find the scouts and them while regaining their memories. For she was going to let the crystal break so that they could be reborn on Earth. At the risk of the darkness being freed. So the Princess and others had to be ready to fight. We had sworn to the Queen that it would be done. And so with her final breath, Queen Serenity had used her powers in having her daughter and the others reborn. The last thing Artemis and I had seen was the last tear that ran down our Queen's cheek as she slowly died upon a broken pillar from the Moon Kingdom. After that, we were put into a deep sleep and sent to Earth after the others." Luna finishes as she shuts her eyes while a tear runs down her furry cheek.

" ...Luna, I am sorry...And the Prince?" Toriel asked with a saddened smile.

" He had fallen in love with another. Named Fiore but Serena was fine with it. She said that sometimes we have to find a new path to the future and not follow the old."

" And what about the other protectors?" Asgore asked as he places his paw on Toriel's shoulder while stepping behind her.

"After Frisk had vanished Serena wanted to find her. So the other Sailor Scouts stayed up there to protect the innocents while we came down here." Mina responded with a sweet smile.

"...The Moon Kingdom being destroyed could explain why the monsters were suddenly forced to the Underground." Alphys added while deep in thought.

" Yes, Queen Serenity helped with the peace between the monsters and the humans. After she had passed most likely judgment and fear took over the humankind. And that was when your people were forced Underground." A gentle yet stern voice responded.

Having the Monster and Mina turn towards the owner. Finding a group of three girls standing at the bedroom entrance.

" Setsuna, Lita, Hotaru, you came!" Mina shouted in excitement as she up towards her three friends.

" Of course we came. After you had reported what just had happened. Rei had the three of us come down here." Lita said as Mina pulls her into a tight hug.

"...How is our sweet Princess?" Setsuna asked as she gives Sans a kind smile.

" Heh, still snorin'. For a Princess, the kid can sleep." The blue hoodie skeleton responded with a small wink.

" Well then while Serena rests perhaps we can give you. The tour of the Underground and maybe discuss a few thing in need." Toriel said as she leads the scouts, Luna and the group of monsters out of the room.

" That is a wonderful idea. Female Clone of King Asgore!" Papyrus said as he follows the others out of the room. Only to stop once he realized that his older brother wasn't behind him.

"Sans?! Are you coming?!"

"Nah. I'm gonna keep an eye socket on the kiddo ere'. You go ahead Paps and once ya' are done. Just text me and Serena and I will meet ya' at Grillby's."

",,, Very well brother!" The younger skeleton responded as he exits the room then shuts the door behind him.

An hour later after the group had left. Serena begins to slowly open her crystal blue eyes. Only to find a blue hoodie skeleton fast asleep in the chair next to her bed with his chin resting in the middle of his bony palm.

"... Sans?" the small pigtail girl as she sits up only to have Sans to quickly open his eyes and look down towards her with white pupils now glowing softly.

" Mornin' there Moon Fairy. Did ya' have a nice rest?" he asked with a small wink.

" I-I feel a little better after my nap," she responded with a soft blush only to earn a soft chuckle from the blue hoodie skeleton.

As he reaches for her long pigtail and gently tugs on it to where her lips were now only a few distance from his permanent grin.

" Heh, I really appreciate you saving my bro an' all but if. Ya' risk like that again I'm am going ta' have ta' punish ya'. Caphice?" he questioned.

Earning a quick nod from a now very red Serena.

" Good little Princess." Sans added while standing up from his seat as he lets go of her soft pigtail.

" I got a text from Paps while you were asleep. He and the others were waitin' for us at Grillby's for a while now." he continues while holding out his bony hand.

With a sweet smile, Serena gently takes a hold of his hand. Only to have Sans quickly pull her towards him. To where she was now leaning against his chest with his arms wrapped around her small waist.

" Hold on tight Serena. We're takin' a shortcut." he whispers softly in her ear.

Causing the short pigtail girl blush softly as she shyly buries her face in the fur of his hoodie.

Before he teleports away with her in his arms.

Once they had arrived Serena gently pulls away from Sans. As she hears her name being called by a familiar voice other than Mina's.

As she looks turns the owner she finds Hotaru waving towards her. With Setsuna, Lita, and Mina standing behind the small child as Toriel and Asgore stood next to them.

" Setsuna, Hotaru, Lita!" Serena giggles as she runs towards them in excitement.

As Sans lets out a low chuckle while following closely behind her.

" I am glad you are well Princess," Hotaru said with a sweet smile as the pigtail girl pulls her into a gentle hug.

"And I'm glad that you are here," Serena responded as she pulls away from the tiny girl.

" Of course when Rei told us that you will be in need of help. We three quickly came in your time of need." Setsuna said with a kinda smile towards her sweet friend.

"...Serena?" Toriel asked quietly having the blond pigtail girl face her with a tilt of her head. As she turns around to face her.

" Asgore and I were talking. And well ..."

" We will like to take you in as our daughter. You will be Princess of the Underground and help protect our people. While the other guardians protect the humans on the surface. And together we will save Frisk. That's if you will welcome our offer of course." Asgore finishes with a small nervous smile.

Only to earn a sweet one from the short pigtail girl.

" I will be honored to." Serena responded while gently taking his paw. Only to glow softly once again.

As the soft light faded around her. She was now standing in front of the king of monsters as Princess Serenity.

" What...How?!" Mina asked in slight shock.

" Her taking back the duties of a Princess. Must have awakened Serenity fully." Luna responded in a happy tone.

" Well, then it would seem that our new friends. Are in good hands." Setsuna added with a sweet smile.

As the other scout's nod in agreement.

"
