"Blake on your left!" Nagisa said

"Got it" Blake a young woman who wore a black bow while holding a high tech looking sword and a clever said "I can't sense him around here" Blake said

"Maybe you better take off your bow to detect him" Nagisa said

"Alright, but you do realise that this bow is the only thing keeping my secret" Blake said unravelling her bow to reveal two cat ears. "Okay, towards the south, five minutes' walk. He'll be there" she said covering her cat ears.

"And where you're from people dislike your kind?" Nagisa asked

"Pretty much, one of the hassles being a Faunus" Blake said

"Really, you think Cat Fauna would be popular" Nagisa

"The plural and the singular is the same, like fish" Blake explained "One Faunus, a dozen Faunus, one fish a dozen fish, See?"

"Got you" Nagisa said


"Target is about five meters ahead, also target has the package. I repeat the target has the package" Blake said sniffing the air.

"You got it ready?" Nagisa asked pulling out an anti-sensei knife while Blake pulled out her katana and folded the blade back into a gun and attached a thin black ribbon to it

"Oh yeah" Blake said as she had her variant ballistic Chain scythe Gambol Shroud ready. Their prey was Koro-sensei and the object besides him: a large pink box. Blake got her weapon ready

"3...2...1...Now" Nagisa whispered as Blake threw her weapon surprising their teacher.

"WHAT!" Koro-sensei said as a black ribbon wrapped around him, Quickly Nagisa grabbed the box. "HEY!"

"Snoozer losers" Nagisa said running off.

"You heard him sensei" Blake said unwrapping the teacher and making a run for it.

"GET BACK HERE YOU TWO!" Koro-sensei shouted


"Did you get it?" Kataoka said as Nagisa placed the item he and Blake stole on Isogai's desk.

"Good, but question is..." Maehara said

"All there, I check it myself" Blake said putting her weapons away.

"Too imagine he had something like this the whole time" Kataoka said

"Well who's going to open it?" Blake asked

"But first Karma!" Nagisa said

"Yes?" he asked

"Secure the room" Nagisa said

"On it" Karma said

"Hey Ritsu can you pass me a dust clip" Blake said as a gun clip slid out with several multi-coloured squares "Flame, Ice, Shadow and Earth. Nice selection" she smirked sliding it into her gun grip. "Save me a piece" Blake said

"A piece?" Isogai said "Of what?

"I think we see what's inside" Kaede said opening the pink box to reveal a cake, and with one whiff Kaede deducted. "It's a chocolate cake made with the finest Swiss chocolate"

"And what appear to be black cherries" Nagisa said

"No wonder Koro-sensei wanted to keep this to himself" Kaede said


Out in the front yard Blake was polishing her katana blade before standing up and flourishing it

"SO the kitty cat has come to play" Koro-sensei said smirking with green stripes on his face.

"Sure have" Black said getting ready

"Begin" Koro-sensei said rushing in at mark twenty, only for Blake to use her natural power she called a Semblance, a manifestation of one personal power as an ability that is unique to that person. Blake's was what she called Shadow, enabling her to leave behind a clone to take a hit; recent she found out she could change the properties of her clone by using a substance on her world called Dust, a crystal that usually held elemental powers. Soon she leapt over Koro-sensei and aimed her clever at one of his tentacles. Only to miss as he dodged it and followed up with a sonic slap. Which made Blake use her semblance again to dodge it, before sliding along the ground and slicing off some tentacles. She smiled as she stood up

"THat was surprising, but what could I have said for a kunoichi" Koro-sensei said

"I'm not that much of a kunoichi" Blake said

"That kiss said otherwise" Koro-sensei smirked

"What are you talking about?" she asked flustered

"So this isn't you kissing Nagisa?" the teacher asked holding up a photo

"G-G-GIVE ME THAT!" she said leaping for the photo and using her first dust cartage to leave behind a fire clone, which burnt Koro-sensei. "Let me cool you off" she said leaving behind an ice clone. "And finally" she smirked jumping over him and using Earth dust to leave a statue of her above Koro-sensei; which landed on him and restrained, "Now I think I earned a bit of cake" she said walking away with the photo in her hand and removing her bow to allow her cat ears to breathe a bit

"Class dismissed" Koro-sensei said dizzily

"So yummy" Blake said with her ears twitching in delight as she tasted the chocolate cake.

"I didn't think cats would like chocolate" Kaede said

"Remember she isn't exactly from Earth" Isogai said

"That's right you're from where was it Remnant?" Kataoka asked

"Yeah" Blake said

"Ritsu have you found anywhere like Blake's description?" Isogai asied

"Sorry, but there are no known worlds like what Blake described" Ritsu said

"Thanks for trying" Blake sighed

"Hey we'll find a way home for you" Nagisa said

"Thanks Nagisa" Blake said taking a bit more cake and squirming in delight

"I think she's enjoying that way too much" Kataoka chuckled.


"Good afternoon class, did you have a good extended break thanks to Miss Belladonna's recent fight with me"

"I trapped him under a stone clone" Blake smirked reclining in her seat before a piece of paper appeared on her desk

"And now you can thank her for my hardest POP QUIZ!" he laughed

"Bastard!" they all snarled before the sounds of guns being loaded were heard.

"Nuh Huh, you're in class" the teacher smirked. Blake placed her pen down and went up the front

"Here" she said before Karma did the same

"So it was a little too easy for you two, okay then" Koro-sensei said two anti-sensei round flew at him while Blake brought out her katana.

"Easy you two" Karasuma said walking past

"Yes sir" The pair said.


After class that day Kaede was packing up when she spotted something on the ground. Picking it up she saw it was a photo, the subject of the photo made her go wide eyed.

"Are you okay Kaede?" Blake asked

"I was" Kaede said in a tone that Nagisa knew was trouble

"What ahppened?" Nagisa asked concerned

"I found this" she chirped showing Blake and Nagisa the photo of them kissing

"I thought" Blake said checking her bag "The octopus!" she snarled.

"Honey, it was an accident" Nagisa said

"Yeah! I tripped and when Nagisa went to catch me, we kissed!" Blake said panicking know

"Yeah, you can even ask Kataoka and Isogai. They were there with us!"

"Maybe" Kaede said in that sweet yet dangerous tone

"RUN!" they two said

"Oh no you don't" she said chasing after them. Soon Koro-sensei poked his head out of the desk with was using to hiding in while using slime mode.

"I love payback" he smiled before grading the papers.
