[P] The foyer, but not for long

Digit hesitated for just a moment. While she really did not like the idea of meeting the matron like this, she liked the idea of staying wherever this was even less. Much, much less.

She darted towards the crossing point between school and forest. As she approached, the light around her started to warp in a nauseating way, the laws of space no longer adhering quite so strictly. She closed her eyes and pushed forwards, flapping harder and harder as the air became almost as thick as jelly around her. Just... a little... further!

With a "pop" that she felt rather than heard, she broke through. The air was normal. Light, normal. School, normal.

Blue-skinned demon descending the stairs wielding a giant spiked club and a fierce gaze even scarier than her weapon?

Oh, so normal...

"There you are!" the matron barked at her. "Young lady, just what do you think you're doing wandering the school corridors in such an indecent state?! You'd best have a good excuse for missing breakfast!"

"Okato-sama!" Digit yelped, clutching her arms to her body as she realised she was still naked. She bowed deeply, fear and ingrained reflexes overcoming the gaps in her memory. "Moushiwake-arimasen-deshita! I... I truly have no explanation for this! I just woke up in a forest... I don't know how I got there, I swear!"

Okato looked down her nose at Digit. "We'll see about that." She reached into her handbag and pulled out a piece of copper, which she placed against her own forehead. "Detect Thoughts!"

Digit shivered uncomfortably as she felt the dorm matron rooting around inside her head, but she offered no resistance. Okato scowled and looked past her, then turned to the pale-skinned man who was coming down the stairs behind her. "Alibaster, where exactly did you pull her from?"

The man took a few steps past the two of them, examining the portal which was still holding itself open. He stayed in the shadows beneath the corridor windows as he walked, and he grimaced when he saw the sunlight on the other side of the gateway.

"It's a material plane," he said, revealing a couple of sharp teeth as he spoke. "Though it's one that I'm not familiar with. Don't look so surprised, there are an infinite number of them out there after all."

Okato's expression had not changed the entire time. "Could a student have sent someone else..." she gave Digit another terrifying glare, "or themself there?"

Alibaster stroked his smooth chin. "It could easily be done with a random teleport, but the odds of something like that leading to an environment safe for life is extraordinarily low. It's unlikely that any of our students would have discovered this plane to travel there intentionally..." he turned to Digit and smiled. It was an amused yet friendly smile. "Especially one whose only magical accomplishments so far only amount to learning a beginner's cantrip."

Okato tutted. "Very well. Since blame cannot be succinctly attributed to you, Digit, your punishment shall be light. Meet me in the courtyard at midnight for a mere two hours of hard labour." She turned away and began heading back to the stairs. "And for the love of the Gods, clean that soot off and put some clothes on! Alibaster, can I trust you to investigate this mysterious plane matter further?"

"Gladl-"

Digit cut him off with a scream.

Okato's glare was upon her again. "Young lady, do not push your luck!"

Digit was exposing herself, limbs splayed wide to reveal her naked body to the dorm matron. She screamed again, and jerkily moved backwards, away from the oni matron and the vampire professor.

Okato took a breath to yell again, then paused and reconsidered. The azure of her iris changed into a bright yellow, stark against her sclera as they turned from white to black. With her eyes like this, the world became distorted... no, it was more accurate to say that her normal vision of the world was distorted, for the sake of day-to-day convenience. Like this, she saw things as they truly were.

Digit was entangled in ethereal tentacles. They emerged from the portal and were insistently dragging her back towards it.

Okato let out a monstrous roar, killing every airborne microorganism within several decametres of her, and charged. With one arm she lifted her club, taller than herself and thicker than her thighs, above her head and swung it brutally downwards. It sliced through the air between Digit and the portal, severing the tentacles and shattering stone tiles where it landed.

The scraps of tentacles on Digit's body dropped away before fading into nothingness. The remaining parts hesitated for a moment, then darted forward and wrapped around Okato's wrist, the wrist of the hand that she was still holding the club in.

As soon as the tentacles touched her, Okato began to feel woozy. Her memories began to jumble, her strength started to drain away, and she felt herself on the verge of losing consciousness. Also notable was the fact that where the tentacles touched her, the sleeve of her prim-and-proper blouse began to disintegrate away into nothing.

"Don't... you..." Okato panted.

"Okato-san, are you alright?!" Alibaster called out to her, reaching a hesitant hand towards her.

"Don't... you... dare... underestimate me!" she bellowed. With her off-hand, she reached down, grabbed the club, and swung it up through the tentacles, severing them once again.

Clearly chastened, the tentacles retreated towards the portal, which began to shrink.

Okato spun on Alibaster. "Are you doing that?!"

"N-no," Alibaster stammered, holding both palms towards the portal. "It shouldn't... it's closing itself!"

Okato snorted like a bull. "Think you can just slink away after trying to abduct one of my students, do you?"

Alibaster saw what was about to happen, but was powerless to stop it.

"Think again!" Okato roared and charged towards the portal. With an almighty leap, she dove through, landing on the grassy forest floor right as the vision of the school vanished behind her.

She stood up, hefting her club on her shoulders, and looked around. The leaves of the trees shook, but there was no wind.

The forest was afraid.

[P] I venture through the portal back into the school.

[GM] You are greeted by the dorm matron Okato, a blue oni wielding a vicious club and an even more vicious scowl. Behind her is the school's Head of Conjuration, the vampire Alibaster.

[GM] Okato chastises you for wandering the school naked.

[P] I apologise profusely and explain that I woke up in a forest with no idea how I got there.

[GM] Okato is not convinced, and uses Detect Thoughts to suss out your true perspective. After finding nothing contradictory, she turns back to the Conjuration Professor and asks him just where he pulled her out of.

[GM] Alibaster informs her that it was a material plane that he's never encountered before. While it would be possible to reach it by teleporting at random, it was unlikely that any student here could access it by accident or intentionally.

[GM] Okato sighs grumpily and lets you off with a light punishment for missing breakfast. As she turns to leave, however, you are grabbed by some invisible **** and dragged back towards the portal.

[P] I scream.

[GM] Okato tells you off at first, then realises that something is amiss and activates her Onime. She sees invisible tentacles hauling you back-

[P] And rushes in to break them with her club!

[GM] Sure, I'll do her a STRENGTH roll.

[GM] 10 + 10 + 1 = 21

[GM] She snaps the tentacles, freeing you. However, they then wrap around her wrist and begin to drain her levels.

[P] Can she roll WILL to resist?

[GM] 20 + 20 - 1 = 39

[GM] Fucking yes she can! She swings her club, breaking the tentacles again. They retreat, and the portal begins to close.

[GM] *Shuffling notes* I'll probably need another portal to show up at some point and get the forest campaign back on track, but we can do a school adventure for no-

[P] Okato dives through the portal before it closes!

[GM] Wait, what? But she's not... uh, I'll roll her QUICKNESS I guess. She'll have to get at least 20.

[GM] 13 + 6 + 1 = 20

[GM] ...Son of a bitch. Alright, Okato makes it through the portal right before it closes. I guess we're doing this now.
