ONLY 2 MONTHS LATE WHOOPS

Byleth is currently enjoying his time off from being the main protagonist of House Isekai in pseudo-retirement on Garreg Island with Megumi.

However, as Halloween approaches, he find his relaxation time rudely interrupted...

[I REALLY WANT TO STAY AT YOUR HOUSE - Rosa Walton]

Byleth sat on the beach chair soaking in the sun and fair weather.

He reached over and grabbed a coconut drink, taking a sip, hearing the ocean waves gently washing up onto shore.

With a deep relaxed sigh, Byleth put the drink back down and looked up to the skies.

His eyebrow raised as his attention turned to the music that was playing.

The radio had come from…what was it called now?

(Sothis) "Night City. V gave it to us, before we left, remember?"

Sothis floated next to him as he gave her a nod of acknowledgement.

(Byleth) "Hm. That future world. Can't say I'm a fan of this kind of music."

(Sothis) "Then why are you listening to it?"

(Byleth) "Was listening to what the kids were up to before the program ended and this song came up."

The last thing he heard was Laura leading her group deeper into the Crystal Tower, and now he had to wait for the next time it aired.

(Byleth) "So, why are you here?"

(Sothis) "For some relaxation time like you. Speaking of, how has vacation been?"

Byleth got up from his chair, taking another sip from his coconut.

(Byleth) "Peaceful. Megu-nee and I have been taking this time to catch up and find out what the new House has been doing."

(Sothis) "Hm. It is a shame the others weren't able to stay as long."

Byleth shrugged.

(Byleth) "I'm sure we'll get our time to hang. But for now we can at least-"

Byleth's phone began vibrating, making the both of them pause as he picked it up, turning off the radio.

[End Song]

(Byleth) "Hello?"

[Isabelle's Voice] "Ah, Byleth! I am terribly sorry to interrupt you at this time, but your presence is required at town hall!"

(Byleth) "Uh, alright. Be right there."

Byleth hung up the phone while turning to Sothis.

(Sothis) "Is an event going on today?"

(Byleth) "It might be to set up Halloween this month. Let's go."

Sothis nodded and followed Byleth to town hall.

[Town Hall - Animal Crossing: New Horizons OST]

Opening the door, they saw Tom Nook, Megumi, and Isabelle speaking in front of the counter.

(Byleth) "Hey."

Megumi and Isabelle gave a friendly smile while Tom Nook stepped to the front.

(Tom Nook) "Byleth! Terribly sorry to call you on such short notice, but it's necessary, yes yes!"

(Isabelle) "It's about the Halloween decorations for this month."

(Byleth) "What about it? Something go wrong?"

(Tom Nook) "On the contrary, fantastic actually! The decoration you set up near the airport is especially great!"

Byleth raised an eyebrow.

(Byleth) "But I didn't set any up yet. Megu-nee?"

Megumi shook her head.

(Megumi) "Er, no. I wasn't planning to until the week before."

Tom Nook blinked twice, processing the information.

(Tom Nook) "Isabelle?"

She started to shake nervously.

(Isabelle) "U-Um…No."

(Tom Nook) "…Huh. Perhaps its in our best interest to take a look together."

The five walked out of town hall and to the airport dock.

In front of it sat a ghastly portal, glowing a deep black and purple ominously.

(Sothis) "I don't think any of our portals has ever looked like that.".

(Isabelle) "O-Oh, maybe it's like a really cool special effect!"

GROOOOOOAAAAAAR!

Everyone jumped back in surprise as the portal began to fluctuate violently.

[Dark Clouds Gather - Fire Emblem: Three Houses OST]

(Isabelle) "A-A REALLY CONVINCING ONE!"

(Byleth) "We need to get back and-"

Suddenly in Byleth's hands, the Sword of the Creator materialized while Sothis became less transparent.

Isabelle's tools formed onto her back, causing her to panic even more.

Megumi clumsily caught a pistol that dropped out from the sky.

(Megumi) "Hey, isn't this…?!"

Byleth quickly glanced at the pistol before realizing who it belonged to.

(Byleth) "Sara's?"

The roar came out the portal again, blackening the blue skies of Garreg Island as the winds came to a dead halt in the air.

(Byleth) "Tch, we can figure this out later! We need to prepare for battle! Tom, get the townspeople to safety!"

(Tom Nook) "U-Understood!"

He waddled away as fast as his legs could carry him, leaving everyone else to defend.

(Byleth) "Get ready, anything can come through that portal!"

Everyone steeled themselves until out from the portal…

…A chair with a frog face popped out and rattled anticlimactically onto the ground.

(Isabelle) "…A froggy chair?"

Everyone slightly lowered their weapons in confusion.

Until the eyes looked directly at them.

(Megumi) "UH-"

[Silent Scream - Final Fantasy XIV: Endwalker OST]

The legs began to mutate into real frog legs before shooting out bones from its green skin.

The legs quickly became grotesque as it grew in size twofold, beginning to tower over the group.

The seat of the chair grew into a gaping mouth with serrated teeth as the smiling frog face startlingly remained the same.

Though the eyes moved and stared directly into theirs.

(Isabelle) "F-FOR THE ISLAND!"

Isabelle rushed forward with her squeaky hammer, hitting the leg and making only an inappropriate squeaking noise.

The frog chair monster grabbed Isabelle and squeezed her, again making an inappropriate squeaking noise before chucking her out of sight.

A green explosion was formed where she disappeared with an unknown voice screaming:

"PLAYER FOUR, DEFEATED!"

Sothis couldn't help but laugh before Byleth elbowed her hard.

(Byleth) "It won't be as funny for us, we're not from here remember?!"

Sothis coughed awkwardly before remembering the rules of world travelling, if they were to get grabbed, they'd explode into meaty chunks instead.

(Sothis) "S-Sorry."

The froggy chair roared into the sky, the three getting into a fighting stance.

Megumi quickly ran into cover while Byleth's sword turned into the whip, Byleth swinging wildly onto its front right leg.

Byleth was able to inflict several major gashes onto the leg, making it stagger.

The froggy chair slammed its injured leg onto the ground, causing the dirt to shoot upwards into a spike.

Byleth jumped out the way, barely avoiding being skewered.

Sothis's arms went wide as magic circles formed in each hands.

Sothis quickly closed them together and formed ice spears behind her, firing them forward at the beast.

Each spear went into the joints of the legs, but it didn't do anything besides make it angrier.

With another roar, the froggy chair leapt startlingly high into the air.

Sothis teleported at the last second before it crashed back onto the ground, looking for its prey.

(Sothis) "Why is this frog so damn durable?!"

(Byleth) "Maybe cause it was a chair before it mutated, how should I know?!"

(Sothis) "Ugh, if I ever see this again at Nooklings, I'm burning it!"

As Byleth and Sothis distracted it, Megumi continued to stay hidden as she gripped the pistol tightly.

She honestly didn't expect to ever fight again, but in hindsight, that was a mistake.

Peeking around the tree, she saw Byleth and Sothis still distracting it.

Taking a deep breath, Megumi moved to another tree that was closer to it.

Though it was far too close for her comfort, one wrong misstep and she'd be crushed.

She steeled herself and pushed herself despite the fear and sprinted to the tree.

Megumi was able to find a foul looking collection of pus and blisters underneath a flat panel where the legs connected, beating like a heart.

Being as far as she was, Megumi was still somehow able to smell it.

Resisting the urge to vomit, she aimed the pistol at it and pulled the trigger.

The recoil scared Megumi as she almost dropped it, still not used to firing a gun.

The shot echoed her location to the beast but not before the bullet hit home.

The spot exploded into a mix of blood and other viscous liquids, seeing their chance, Byleth and Sothis leapt into action.

Sothis had her arms extended once again, but this time forming a shield around all three of them.

Byleth split apart one of the legs with a wide slash, making it fall over onto the ground.

Blocking the blood that shout with Sothis' shield, Byleth got on top of the chair and jammed the sword into the eye.

Megumi repeatedly pulled the trigger as the bullets hit the back of what she presumed was the head.

The froggy chair continued to flail wildly, trying its best to throw Byleth off.

Megumi almost squeezed the trigger until the chair faced her direction, the gun aiming straight at Byleth still hanging on.

It leapt at her as Megumi dove out the way, tumbling onto the ground after being launched from the impact.

Byleth was finally launched off, letting go of the sword as he landed perfectly, clenching his fists.

Sothis quickly clapped her hands together, dropping the shields as her hands sparked with electricity forming.

And an instant, a bolt of lightning struck the chair, sending it howling and shaking the very air around them.

(Byleth) "MEGU-NEE! PISTOL!"

Shaking off the ringing in her ears, she tossed the gun without a second to waste, Byleth catching it and aiming the pistol at the chair's other eye.

(Byleth) "ALLOW ME TO DEMONSTRATE!"

Firing one last bullet, it pierced the remaining eye, making the chair's legs give out underneath, going completely flat and going still.

The dark clouds above them began to fade and one last hair raising scream, the chair begin to collapse into itself, before exploding into a black and purple mist.

Although the threat was finally gone, the ominous portal remained in front of them.

[End Song]

Isabelle came back, clenching her head.

(Isabelle) "Ow...! What just happened?"

Byleth looked at the pistol, then back to Isabelle.

(Byleth) "We don't know, being honest. That wasn't from our world. Megu-nee?"

(Megumi) "We just had zombies, not...froggy chair abominations."

Tom Nook came rushing back with his nephews, all wielding hammers and wood.

(Tom Nook) "Stand aside, everyone! We're going to build a containment fence around this portal!"

(Timmy) "Yes yes, this is not good!"

(Tommy) "...not good!"

Sothis realized she could see what was inside the portal.

It looked like a massive castle was on the other side.

(Sothis) "I think we can go through this portal."

(Megumi) "What?! Are you crazy, if something like that came through, who knows what else could?"

(Byleth) "I agree, we need to prepare a defense. Can we call anyone to help?"

Sothis ignored the two as she floated closer to it.

(Sothis) "Well, sure that froggy chair from hell came out of the portal, but so did Sara's pistol."

Megumi and Byleth looked at each other, then Sara's pistol.

Now that they could take a closer look, it was indeed pulsating a dark purple glow.

(Byleth) "The hell...?"

(Sothis) "What happens if we-"

Sothis poked the portal with her finger, making it shake violently and open wide.

(Sothis) "OH CRAP-"

The portal began sucking the three of them in, Sothis going in first screaming.

Megumi didn't have time to scream before she lost her footing and went torso first into the portal.

(Byleth) "MEGUMI!-"

Although Byleth was already getting pulled in, he reached out his arm after Megumi, vanishing into the portal with the other two.

As soon as the three of them disappeared, the portal calmed down, leaving the others completely bewildered.

(Tom Nook) "...Nephews, we start construction right now."

As Timmy and Tommy got to work, he had Isabelle hold a white sign for him as he wrote something down.

"DO NOT TOUCH"

(Isabelle) "S-Shouldn't we go after them?"

(Tom Nook) "From what they told us of their previous adventures, perhaps this won't be too different? And I'm afraid we're out of our element here..."

(Isabelle) "True...I hope they'll come out alright."

...

Sothis had Megumi, then Byleth land on top of her, knocking the wind out of her stomach.

(Sothis) "G...G-GET...OFF...ME."

Megumi quickly got up, accidentally punching Byleth off.

(Megumi) "O-OH MY GOODNESS, I'M SO SORRY!"

(Byleth) "Agh, damn it! D-Don't worry about it, Megu-nee. And as for YOU-"

Byleth pointed at Sothis prepared to scream, but quickly stopped as his eyes went wide.

(Sothis) "I'm sorry, okay?! I didn't know-...What?"

Sothis and Megumi turned around and froze.

(Megumi) "W...What...?!"

(Byleth) "...Is this something from Fodlan?"

(Sothis) "I think we'd both know the answer to that by now, the hell is this?"

Then everyone heard something scraping across the floor behind them.

Something...plastic.

And when they turned around, it was another Froggy Chair.

Byleth and Sothis got in front of Megumi prepared to protect and fight before realizing no weapons were materializing. In fact, Sara's pistol was nowhere to be found.

(Sothis) "What, do you want another fight?!"

The chair simply stared at them with its vacant blue eyes.

It said nothing.

(Byleth) "...Hello?"

(Froggy Chair)
