While The Gang Are at Blueberry Academy
BGM: Bowser Battle (Mario and Luigi: Partners in Time)
Loud screams echoed all over Daisy Cruiser as passengers ran away in terror as several Grimm climbed the cruise ship or dropped off by Griffons and Nevermores. What made things more terrifying was that a few Grimm decided to man a few smaller ships to surround the cruise ship.
The Captain of the ship blew the horn of the ship to try and scare off some of the Grimm, but that simply annoyed them as one of them burst through the glass.
The Toad Captain let out a growl. "Everyone out! I'll deal with this myself." He said as the crew ran off as the captain got in a fighting stance, facing down a Beowolf. "Hooooo haaah!" He exclaimed, throwing a few air karate moves as the Beowolf snarled.
The captain smirked, simply doing a "Come at me" gesture as the Beowolf charged right for him.
On the deck, everyone else had nowhere else to go as they looked over the railings to see a few Grimm sharks circling around the ship, eager to have a feel for those who dared to go overboard.
A Tempest floated over the ship and then landed on top of it, latching its tentacles on the side of the boat. A few passengers tried to fight it off, but a few Blooper-like Grimm landed in front of them, where they were all black and their nubbin-like arms were bones as their own tentacles on the bottom were nothing but none as well. Their eyes were a sinister red where the Blooper Grimm floated up and aimed their bony undersides and spat out ink on their weapons, which disintegrated them instantly, forcing the passengers to back away.
The deck underneath them started to crack as the Tempest began to slowly tear the ship apart in two, ready to send everyone into the depths below.
"We're gonna die!" A Toad whimpered, hiding behind a barrel.
At that moment, someone bravely walked toward the Tempest, wearing nothing but a light blue one piece bikini that had Lumas decorated on it and had straps that went over her shoulders and was modest enough to cover her thighs.
The Blooper Grimm turned toward this intruder and started to attack, but she waved her hand as they were magically thrown off the ship as she snapped her fingers as lightning bolts came down and destroyed them.

"I'm sorry, you must have booked the wrong cruise."
Magic swirled around Rosalina's body.
BGM: Main Theme - Inferno (Fire Emblem Warriors: Three Hopes)
"Allow me to help you find your destination."
The Tempest roared as a storm swirled above it, lightning crashing down all around as one lightning bolt came down on Rosalina, but a magical barrier protected her as she telekinetically pulled the Tempest off of the ship and pushed it back.
With a loud screech, it summoned an army of Grimm Parabeetles flying toward her, shooting out spikes out of their bony shells. Rosalina swiftly blocked them as a few of them flanked her from behind… only for a sword to pierce through them to destroy them instantly.
"Hmph." Byleth smirked, decked out in her bikini, pulled the Sword of the Creator toward her. She glanced to the side to see a Beringel charging at her and swinging its arms down. Byleth backflipped away and flicked the Sword of the Creator, but the Beringel grabbed a hold of the tip and jumped off the boat, taking Byleth for a ride as he landed on top of a Griffon, making it cry out in surprise and then he threw his wrist, making Byleth crash through the window as she landed inside of a room, destroying part of a bed, wardrobe and desk.
"Nnngh…! Agh!" Byleth groaned as her back took most of the blow, not to mention some sharp glass cut up her back pretty good, along with cutting part of her bikini as the left strap was also cut off from the glass.
The Beringel jumped through and beat his chest as Byleth shook off the pain and glared at the Grimm.
"Let's go, big guy."
The gorilla lunged forward, swinging his arm at her as she weaved her head as she put her sword away and grabbed his arm. "HAAAAAAAAAAAAH!" She turned around and threw him out of the room and into the hallway.
Byleth then ran toward him as the Beringel got up as he ran forward as they both swung their fists at each other, both of their fists connecting into their faces as they were knocked back a few feet. In fact, Byleth's punch was enough to make the Beringel's jaw dislocated.
However, the Beringel put his jaw back into place and snarled angrily at Byleth who wiped some blood from her lower lip. The Beringel lunged as Byleth shattered some glass and pulled out a fire extinguisher as she shoved it into the Grimm's mouth. It chomped down as foam splattered everywhere, making the Beringel roar in surprise.
The Beringel got out of the foam cloud but noticed Byleth was long gone. It looked down and saw some blood moving through the hallway. It followed the blood trail until he went into the indoor swimming pool where he spotted Byleth in the pool.
With a roar, the Beringel charged in and jumped into the pool. Byleth immediately went into Awakening mode and teleported out of the pool as the Beringel landed inside of it. Dorothea walked inside, drinking a smoothie.
"Present for you!" Dorothea threw the smoothie toward the Beringel as she snapped her fingers, where it electrically exploded, causing the Beringel to roar in agony as the pool violently electrocuted the Grimm until it faded away.
"That's a waste of a smoothie."
"Eh, wasn't my favorite blend." Dorothea shrugged as Byleth fell on both knees, groaning. "Whoa, easy…" She whispered, using some healing magic to heal her wife up. "You okay?"
"Well, I just got slugged by a gorilla… that's never fun…" She chuckled lightly.
Back outside…
The Tempest screeched as it used its tentacles to pierce through Rosalina's barrier and grabbed a hold of her waist, bringing her to it as it let out a growl and started to squeeze her… however, Rosalina suddenly turned a dark cosmic blue.
Before the Tempest could even do anything, the tentacles started to distort around her as Rosalina suddenly exploded into a miniature black hole, proceeding to eat the Grimm alive as it let out a screech and tried to pull away, only for a comet to come down and slammed into the Tempest to stun it, and then more black holes surrounded the Tempest to pull it apart piece by piece.
"You like that Cosmic Spirit?" Rosalina casually asked, sitting on top of the ship and watched the Tempest be torn apart. She waved her hand as a cosmic lightning bolt pierced through the Grimm, splitting it in two as the black holes spaghettified what remained of the Tempest, as the storm clouds disappeared.
Rosalina flew up into the sky and clapped her hands before spreading them apart as comets rained down on the stolen ships and eradicated the Grimm.

Rosalina gently descended as she proceeded to magically repair the ship that the Tempest nearly broke apart. The crowd cheered for her as she turned around and smiled, giving them a friendly wave.
"Oh, thank you so much!" The captain approached, having a few bruises on him. "You are our hero, Rosalina! If it weren't you for you, Daisy would have one less cruise ship."
"It's not just me you should be thanking." Rosalina said as Byleth and Dorothea approached.
"Oh? Is your whole family here?"
"Just the three of us."
"Ah, very well. Tell your family I said hi! Our next stop will be Koopa Beach!" He walked off.
Rosalina turned toward Byleth. "You feeling okay, honey?"
"A little sore, but I've been through worse." Byleth admitted. "Though, my bikini's seen better days…" She said, glancing at how ripped up it was but still covering her… barely.
"I'd say we take it off and throw it away~" Dorothea giggled while letting out a playful "Mrow" with a seductive smirk.
"Now now, not here." Rosalina rolled her eyes with a smile.
"Oh, but of course." Dorothea snickered as they walked off back to their rooms where Byleth and Dorothea would get it on while Rosalina was next door, reading a book with the sea breeze blowing out of the window.
Going on a cruise with her daughter and daughter-in-law was fun, but she had to admit, it wasn't as fun without her whole family to enjoy it. Tai wanted to go, but Raven dragged him off with Maia to go camping for old time's sake. Oran and Anya were a little sick so Loid opted to keep an eye on them. Ruby and Yang were off in Paldea with their friends, Qrow wasn't really into cruises and Bereto wanted to work up the courage to ask Yuri out, but mentioned he'd go for a cruise next time.
So really, it was just her and the ladies.
But at the same time, Byleth looked like she needed a vacation to get her mind off things since she retired from being a therapist.
"What? Are you absolutely sure about this?" Bereto asked in surprise.
Flashback!
BGM: Friends in My Heart (Kingdom Hearts HD 2.5 ReMix)
"Honestly, you deserve it more than I do."
"Hmm, true… but you have been getting better after that… incident with Ruby, but… you know, you could take classes like I did-"
"Yeah, but if I get a degree on that, then people would go to me and you'd be giving therapy to tumbleweeds. It'd be back to square one."
Bereto folded his arms. "Honestly, you make a good point… it's a bit frustrating."
"Right…"
"Now hang on a moment. I wouldn't retire from it just yet." Bereto mentioned. "In all honesty, you could simply just do therapy within the family and I'll take care of the rest. You're the go to of the family if someone wants to talk your ear off. You don't mind that, do you?"
"Not at all, but… I feel like-"
"I'm stopping you right there. I get that you want me to succeed and you want to do something different when you're not teaching at Garreg Mach. Hell, Combat Instructor sounds like something you'd excel at, hell, you turned the Ultimate Gamer into a boxer. Now she's on par with Little Mac and Tifa. But retiring from therapy? You're crazy."
"What are you talking about?"
"The whole family loves you. Where would anyone go to if you don't offer words of encouragement? Sure, they can go to mom and we all know how amazing she is, but even she can only do so much, even if she seems she can do it all as the cosmic queen herself. You're great with them all. You retire from that and well, things would get awkward."
Byleth sighed. "You're right… sorry, I just have a lot on my mind after I stole your thunder with Chiaki."
"Ah, that? Don't worry about it. I was a bit swamped with a few patients that I couldn't get to what was eating her up. So in a way, I'm thankful that you stepped in. Hell, if I ever need an assistant-"
"Bro, if I was your assistant, people would come to me and leaving you dry as a Dry Bones."
Bereto laughed. "Yeah, true… sorry, I'm just trying to offer something that's the best of both worlds."
He put his hand on his sister. "We'll all support your decision on what you'll do, you know that, right?"
"Right."
Byleth closed her eyes. "Maybe I am being a bit silly… keeping it in the family sounds better for me."
"That's more like it. You're retiring, but… semi-retired at best. Combat Instructor by day, a caring loving sister, daughter and wife at home."
Byleth smiled. "Thanks, bro…"
Both of them hugged it out.
End flashback…
Rosalina smiled. She knew Byleth was going through a lot after what Eggman had done to her, especially since she was worn out by the time she got back from the Starfall Islands.
A cruise was just what her daughter needed.
Not just some silly ol' vacation to Delfino, considering they've been there plenty of times, but a cruise just to mix things up a bit.
It's been about a week since they were on a cruise, visiting many islands all over the Mushroom Kingdom and all over Remnant. Sure, there was the occasional Grimm attack, but throughout the week, she noticed how happier and more relaxed her oldest was.
And just like her Lumas, if her kids are happy, then that's what makes a mother happiest.

Loud ship bellow!
"We are now stopping at Koopa Troopa Beach for a little while. Prepare to disembark!"
Rosalina got up and stretched as she prepared to walk out of her room, right as the same time as the ladies finished having their fun together.
Rosalina walked out at the same time as them, Byleth having a different bikini top that was even more revealing than her last one, but none of them seemed to care that much as they walked out.
BGM: N64 Koopa Troopa Beach (Mario Kart 7)
The ship docked near the beach as Rosalina, Byleth and Dorothea walked off the ramp as they looked around.
They would see Koopas sunbathing while they would also see a rock shaped like a Koopa, while some Toads were already playing in the water along with a ramp with a booster on it. Aimed directly toward a hidden cave while a waterfall slammed down into a small pond, where there was another ramp that seemed to go over a rock in the shape of a Koopa Shell.
"So, this is where they sometimes do Mario Kart, eh?" Dorothea mused.
"I can see why." Byleth said as an airplane flew over them rather close. "Whoa!"
"Hmm?" Rosalina levitated up to see what was going on. "Oh, that's why. Sunshine Airport is nearby."
"That's good to know." Dorothea said as they walked around the beach.
"Mantine Surfing! Anyone up to try some Mantine Surfing?" A Toad called out.
"...I've always wanted to try that." Byleth said as she took off.
"There she goes." Dorothea smiled.
"Yeah." Rosalina giggled. "...By the way, have you heard anything about Garreg Mach recently?"
"Not that I know of… I've heard a rumor about a possible expansion, but I haven't heard about the details."
"Hmm… curious. I wonder what the expansion would be…"

Meanwhile, at Beacon Academy…
Sothis emerged from the elevators. "Hey, Ozpin."
"Sothis? This is an unexpected surprise." Ozpin said as he noticed she was joined by Rhea, Seteth and Flayn. "What can I do for all of you?"
"We've been talking for a while and… well, we have a proposition for you." Sothis explained.
"Fire away."
"How would you like Garreg Mach and Beacon Academy to merge as one~?"
Ibuki: Whoa! For real?
For real!
Deadpool: Interesting!
