"...But I still admit you arrived sooner than expected" Y/N walked through opened doors, carrying snacks in his arms.
"Y/N!" Kaguya rushed towards him trying to give him a hug, but he dodged by stepping aside.
"We're carrying snack, you know?" Origami commented and walked past her, also carrying snacks in her arms and looked at Shido "Hmm... So that's how male Shiori would look like, can we bring him with us?"
"You already have your maids to rape..." Y/N sighed.
"ORIGAMI!" Shido rushed towards her and she also stepped aside, but also make him trip over his foot and land on floor.
"That was straight asshole action, Origami..." Y/N gave her look of disapproval "There is line between being a troll and an asshole"
"I'm both" Origami answered while they put snacks on the ground.
"How about I plug one of your holes then?" Y/N sat next to her.
"A rather attractive proposal, but I doubt it will last for long..."
Girls and Shido looked at them visibly confused as they continued their conversation.
"Do you really think that all those years of being single don't pay off?" Y/N opened chips and started eating them.
"You have a good hand experience to do it, but would it last that long against me?" She also opened the chips.
"You never know till you try it..." Y/N shrugged his arms "Wanna try it now"
"Hey Kaguya..." Confused Shido looked at her "...I can't understand what they're talking about..."
"First time?" Kaguya asked out of nowhere.
"Huh?" Shido looked at her confused.
"We're talking about gluing her mouth, so she will finally shut up!" Y/N looked at them "You guys want some snacks?"
"Funny, I was thinking that you were talking about using polearm against me" Origami smirked.
"Do I look like bloody Vald the Impaler?" Y/N raised a eyebrow "For a second I thought you were talking about something more kinky..."
"You mean sex? Yeah, though about it too for a second" Origami casual said.
"Yeah, I though about it too" Y/N admitted "Did you bring any kind of protection by the way?"
"No, you didn't bring any too?" Origami looked at his surprised.
"Nope. Now It would be really problematic if we had sex..." Y/N started pondering.
"...I heard that you can't be pregnant from anal" Origami also started pondering.
"But shouldn't first insert be a normal one?" Y/N pointed out.
"I don't want to be normal girl" Origami admitted proudly.
"But not all girls like it..."
"...You never know till you do that..."
"...You make it sound like I'm the one giving a entrance..."
"...Why not do it? It's good to experience new things, we can even share the same horse and hold hands during it..."
"...No thanks, this is wrong on too many levels--"
"GUYS!" Shido lost his patience "They are people that are dying and you're having a sh*t talk!"
"Well, that's kinda rude of you..." Origami commented.
"From the part of my friend speech that I paid attention to..." Y/N started.
"...You mean that phone call you made while you were cooking?" Origami interrupted.
"...It looks like that mine world, alternative timeline and your world are slowly mixing with each other" Y/N finished ignoring Origami.
"How we can stop it?!" Shido looked into Y/N eyes.
"I and Origami are dark spirits that invaded Origami from your timeline. She's inside her now..." She pointed at Origami with long hair "...And keeps the worlds connected"
"Wait a second!" Origami with long hair stepped foward "How you expect me to belive that?!"
"Let me call you Lorigami to make it easier" Y/N pointed at Origami "Then how do you explain why you look like twins? You can even make blood test, she's you and you are her"
"I still don't believe it" Lorigami said unconvinced "How could different timelines exist at first place"
"When something travels in time, it creates infinite amount of another timelines. You're basically trapped in a endless circle you named fate" Y/N explained.
"Then you two are too, right?" Lorigami asked confused.
"No, my world is unique since the time there is already convoluted, this mean that if I travel to another world or timeline I create unique paradox" Y/N explained "Any more questions? "
"I..." Lorigami looked away confused, trying to process everything "No, I belive you... Bearly, but yes"
"Then what we need to do?" Shido asked.
"For now leave me and Origami alone, we have something to discuss. She will join you later and tell you what to do" Y/N stood up.
Shido nodded and he left the roof with other girls.
"It's starting..." Y/N pulled out his greatsword and armor materialized on him "...You know what to do"
Origami stood up and hugged his back.
"Please... Promise me to stay safe..." She whispered.
"I can't promise that" Y/N sighed "Now go, make sure everything will go according to plan"
She slowly walked away towards the roof entrance.
"I'll be back..." She mumbled and ran down the stairs.
"You and your sense of humor..." Y/N smiled under his helmet.
A dark sphere suddenly landed on the roof, causing it to shake.
Soon the smoke settled, revealing Kurumi.
Her eyes were lifeless and skin pale, with dark veins giving her macabric look. Her astral dress was tainted by darkenss and left hand was missing.
"We meet again..." Y/N gripped tighter his sword "...For the last time..."
Fire mixed with yellow lighting started appearing on his body and extended to his sword.
"Phase three... Initiated..."
