It's roughly after 9am. The sun shines brightly signifying the start of a beautiful day. The sun beams creep through the blinds and shine over the eyes of a sleeping Usagi, lying under the covers like a bundled-up baby with Luna asleep on the pillow above her head. Her eyes slowly flutter open as the sun beams wake her up.
"Mmm", Usagi mumbles as she slowly wakes up with a stretch and a yawn, then plops back down onto her pillow. Her gaze finds its way towards her nightstand, where she reads 9:07am on her alarm clock. "GAAAAAHHHHH!"
Her shriek can be heard from outside her house, scaring Luna awake. Luna is now perched in the head of Usagi's bed frame as if under attack.
Usagi rushes through her room gathering her things and throwing off her pajamas. "I CAN'T BELIEVE I OVERSLEPT AGAIN! I'M LATE! I'M SO LATE!"
Luna tries to calm her down. "Usagi. Usagi!"
"I'm gonna get in trouble for sure this time! How can this happen?!", she yells as she is now in her bra and panties rummaging through her closet for her uniform.
"Usagi, settle down!", Luna yells.
Usagi turns toward her trying to throw on her uniform. "Why?! It's-" She pauses as she sees Luna pointing at her calendar. "…It's Saturday", she says with a sigh as she drops her uniform.
Luna replies with a nervous smirk. "Have we calmed down now?"
"Mmmnnnngh", Usagi groans as she plops face down back on her bed.
Luna hops down from the headboard. "You're just going back to bed? I thought you were spending the day with the girls."
"Mmm sorry, no one home. Leave a message", Usagi replies, her words muffled by her bed covers.
"But there's gonna be ice cream later."
Usagi springs back up with a gasp. "Ice cream? Now that I can do!" She starts getting cleaned up for the day.
Luna sighs with a smile. "The greatest motivator in the world: food."
Later, around 11am, Usagi meets up with Rei, Minako, Ami, and Makoto. The five best friends spend the day shopping at the mall, mostly with Minako buying new pretty outfits. They even visit a nail salon in the shopping center to get manicures and pedicures. Usagi can barely keep her composure during her pedicure on account of being very ticklish.
Afterwards, they decide to hang out at Usagi's favorite video arcade. Usagi seems addicted to a particular fantasy adventure arcade game. She gets frustrated when she cannot defeat the second level, thus she keeps a large cup of 100 yen coins within arm's reach. Ami seems to be the only one capable of winning the claw game consistently, utilizing her advanced knowledge of angles to aid in her precision. She gives most of the stuffed animals to kids in the arcade, but keeps a blue plush swan for herself.
At 6:57pm, just as the sun is doing down after a fun-filled afternoon, the girls retire to their favorite café for ice cream. They sit at a round table outside to enjoy their treat. Usagi devours a large ice cream banana split by herself.
Minako is perplexed. "You know what I'm still trying to figure out? How is it that you put away so much food all the time and not gain a pound?"
Usagi shrugs with a mouth full of ice cream. "I dunno", she says. "I never really thought about- ow ow ow ow OW OW OW OW!" Usagi hunches forward gripping her head from a brain freeze.
Ami giggles. "You should really slow down, Usagi."
Rei snickers. "'Slow down is not in her vocabulary when it comes to food."
"Hey", Usagi replies, "I resent that remar- owie owie owie." The others laugh as she gets over the brain freeze shortly after.
Makoto sits back as she licks her ice cream cone. "You know, this was a good day. I needed this."
Ami nods. "Yes, it was. We really should find the time to do this more often."
Rei sighs. "Yeah I don't get out enough. Grandpa keeps me busy at the shrine all the time."
"He's a nice man", Minako replies, "but he really should ease up on you so you can get out more. You're not getting any younger, you know."
Rei raises an eyebrow at Minako. "What's that supposed to mean?"
Makoto laughs. "Can't find a cute guy if you're cooped up in a shrine all day."
Rei smirks. "Oh really? Like I'm the only one at this table who's single."
Usagi quickly raises her hand. "I'm not!"
"Oh shut up!", the other girls yell in unison.
Usagi covers her head in protection. "Ah, don't yell at me!"
They all laugh from their exchange about dating. Just as they start to get back to their ice cream, a male passerby walks by their table as if minding his own business. Just as he reaches them, he snatches Makoto's purse and makes a break for it.
Makoto quickly gets up first. "HEY!"
"That jerk!", yells Rei as they all start to get up.
Makoto starts to run after him. "GET BACK HERE, YOU BASTARD!"
Before Makoto can start closing the gap, a man in a business suit snatches the purse away and trips the assailant to the ground. The Caucasian man, appearing to be in his mid-to-late 30s with black hair, tosses Makoto back her purse as he keeps his eye on the assailant getting back off the ground. Another man is with him – an older balding gentleman in his late 50s or early 60s, also wearing a suit.
Rei is surprised. "Wow, that guy is fast."
Usagi looks at him. "Is he American?"
The businessman speaks to the older gentleman with him. "…Bring the car around. This'll only take a minute."
"Right away, sir", the man replies with what sounds like a British accent.
When the older gentleman leaves, the assailant is suddenly joined by four other men dressed similar to him, all appearing to be a simple street gang commonly attributed to petty thefts and violent acts. The first member holds himself as if he is the leader of this group, sending the other four to surround the American businessman and jump him at once.
Makoto looks concerned. "This isn't good", she says. "We need to help him."
Usagi looks at her confused. "Wait, transform? Here? Now?"
Makoto hands her purse to Ami. "Screw transforming! I'm kicking these guys' butts for picking on a defenseless-"
Just as Makoto begins to make her way there, she stops as the four gang members attack the businessman all at once, then all four are beaten down easily, much to the surprise of the girls.
"Wow!", says Ami with wide eyes. "Those moves!"
Makoto tries to analyze him during her disbelief. "That was…Krav Maga,… Muy Thai,… Shotokan, Kung Fu, Jiu Jitsu,- …This guy is a walking martial arts encyclopedia."
The ring leader is in disbelief that his gang was taken out so easily. Still, he pulls out a pair of nunchaku and starts twirling it around as if a master of the weapon. The businessman's expression does not change. When the ring leader rushes in to attack, the businessman counters his attack by catching his wrist and putting him into a hammer lock, causing him to loosen his grip on his nunchaku as he shrieks in pain. The businessman puts him onto his knees and has him face the girls.
The businessman leans in to talk to the ring leader. "Now I suggest you apologize to that young woman, or you won't have an arm to showboat that weapon anymore." He tightens the hammer lock to make him shriek in pain even more.
The ring leader cooperates with no more resistance. "S-s-s-sorry."
"Smart man", the businessman says as he elbows the side of the ring leader's head to knock him out, then leaves all five men laid out in the street. He then stands up, dusting himself off and fixing his jacket.
"Wow", Makoto says to him. "Thanks for that."
"No problem", he says.
"That was amazing!", Rei says. "…Who are you, anyway-"
Just then, the British gentleman pulls around in a black luxury sedan. He climbs out and opens the door for the businessman.
"Gotta run. You girls take care now." He climbs into the back of the sedan.
After shutting the door, the British gentleman tips his hat to the girls, then hops back into the car and drives off.
"Whoa, he must be loaded", says Minako in disbelief.
"And he can fight. Wish I had moves like that", says Usagi in awe.
Makoto starts pondering. "Yeah, you know…he kinda reminds me of my ex-boyfriend."
The others fall over animé-style. "REALLY?!", they all say in unison.
At this moment, Luna and Artemis run up to them. "There you are. Thank goodness we found you", Luna says in relief.
Artemis looks surprised at the laid out bodies in the street. "Whoa. What happened to them?"
Ami replies, "Long story. What's going on?"
"The Negaverse is on the move again", Luna says with authority. "You're needed now."
"Lead the way", says a determined Rei.
Usagi looks at her unfinished banana split. "Aww, but I wasn't finished."
"Will you c'mon?!", yells Rei as she pulls Usagi away with them.
The cats lead the girls downtown. They remain concealed and see a natural history museum down the block, where people are running out of the museum from something frightening inside. Even museum security is running away.
"There", Luna says.
Rei is trying to make sense of the scene. "What's happening?"
Artemis's ears twitch. "I don't know, but there is some serious Negaverse energy coming from that building. You girls know what to do."
"Then let's not waste any time", says a now determined Usagi. "MOON COSMIC POWER!"
"VENUS PLANET POWER!"
"MARS PLANET POWER!"
"MERCURY PLANET POWER!"
"JUPITER PLANET POWER!"
They all yell "MAKE-UP!" in unison to begin their respective metamorphoses into the Sailor Scouts.
They all run into the museum after the building is evacuated. They look around the dim-lit exhibits and hallways, searching for anything out of the ordinary. They finally make their way to the grand showroom, where they see a strange figure procuring an artifact from a glass case on the opposite side of the showroom. He wears a Negaverse-like uniform, white mohawk, and light purple skin.
Sailor Moon yells "Hold it right there!"
The man looks back at them. "Hmm?"
Sailor Moon continues, "I don't know who you are or what you're up to, but if you're taking anything from this museum, you'll have to go through us!"
They all start striking poses. "Sailor Jupiter!"
"Sailor Mercury!"
"Sailor Mars!"
"Sailor Venus!"
"And I'm Sailor Moon, Champion of Justice! I will right wrongs and triumph over evil, and that means you!"
The man chuckles as he turns to them completely. "Sailor Scouts. The master says you like to waste time with your speeches and poses."
Sailor Moon notices he's holding a gold talisman in his hand that he pulled from the glass case. "What's that?"
Sailor Jupiter clenches her fist. "I don't know, but he's not leaving with it! JUPITER SPARKLING WIDE PRESSURE!" She launches her attack at the man, but it is suddenly blocked by a creature appearing out of nowhere with red eyes, a shield for an arm and a scythe for the other. "What the?!"
Sailor Moon looks around and notices they are surrounded by a dozen similar creatures. "AAHH! Where'd they come from?!"
"You see, that's the problem with you amateurs", the man says egotistically. "You spend so much time dancing and making speeches that you don't even know you're about to die."
Artemis and Luna are hidden on a corner of the room. "This is bad", Artemis says. "This is very bad."
Sailor Mars speaks as the team gets ready to fight. "Keep it together, girls. We got this."
"Uh huh", the man says. "Well, while you make yourselves acquainted with my Centurians, I must be going. Places to go, people to-" He is cut off by the lights in the building being completely shut off. He looks up as the only light source is the moon shining into the skinny glass ceiling above. "What's this?"
The girls look around. "What's going on?", says a confused Sailor Moon.
A weapon can be heard thrown and hurling towards the Negaverse man, hitting him in the hand and making him drop the talisman. The weapon can be heard planting itself into the ground. He shrieks in pain and tenders to his hand. "ARGH! Damnit!"
"What was that?", says Sailor Jupiter as she tries to make sense of the situation.
A slight shuffle can be heard above them. Everyone looks up to see the silhouette of a caped man standing on one of the beams.
Sailor Moon gasps. "Tuxedo Mask!"
The caped man swoops down and attacks the Centurians with powerful strikes and fast movements.
"When did Tuxedo Mask start moving like that?", says Sailor Venus in awe.
Sailor Mercury equips her visor to get a better look as the man punches one of the Centurians and electrocutes it with his fist before moving on to the next bunch. "That… can't be Tuxedo Mask."
The caped man takes down all of the Centurians on his own. The Negaverse man is dumbfounded.
"Nobody has moves like that. Who are you?", he says with curiosity in his voice.
As an answer is awaited, the caped man steps into the light with his back to the Sailor Scouts, leering right at the Negaverse man. The Sailor Scouts are in disbelief when they can now make out a black ripple-edged cape and a mask with ears that resemble a bat's.
Wide-eyed, Sailor Jupiter utters, "No way. …That's…"
