Hi there TF here with my first story, I primarily wrote it out of a personal desire to add a Tsukihime crossover to the website and my belief that a crossover with Tsukihime won't be inundated with views. To give some background this crossover will feature a Shiki taken shortly after Tsukihime's epilogue, following on from Arcueid's true ending which will be briefly explained in the story. I plan for this story to end during the second season of Konosuba (I've read up to volume 12 of the LN so no excuses for contradicting it). Any reviews are welcome, I'm under no illusions that my writing could use some work and am open to advice. Hope you enjoy.

Aqua-sama is quietly sobbing in her chair, true to her status as a goddess of water she has been in tears for the last few minutes occasionally pausing to call me "Creepy blindfold guy". Prior to this she had been waving her hands in front of my face while asking me if wearing a blindfold is supposed to made me look cool, she then spent several minutes laughing at her own joke and declared that I must have died by walking into traffic.

It looks like it'll be a while so I suppose I should get around to talking about myself and Arcueid Brunestud. My life had been perfectly normal for the most part, I spent most of my life living with a small branch family after an accident forced me to leave the family estate. I had been recently recalled to the Tohno estate by my sister, Akiha after she became the new head of the family. I'd been looking forward to seeing her but after my return I found that my relationship with my sister was quite strained. While I had lived an easy life as a typical student, Akiha had been forced to take up my responsibilities as the head of the family in my absence. It was while wasting an afternoon avoiding my estranged sister that I met her. It was a memorable meeting or more accurately it was a catastrophic meeting- I came to my senses in her apartment to find her cut into seventeen pieces.

It strikes me as incredibly unlikely that anyone else could have found themselves in my position, for all that I was a normal high school student I doubt anyone else would have followed a stranger home and killed them. I awoke soon after at the Tohno estate convinced the encounter had been a bad dream, after all I was a completely average person. It wasn't until I encountered her again on the way to school that my existence as a normal person ended. The events that followed and my forced conscription into a battle against immortal vampires would not have occurred were it not for my abnormal decisions that afternoon, so its safe to say that the tragedies that followed were my fault.

Arcueid Brunestud is a vampire, I probably don't need to explain what a vampire is in detail but there are several differences that I should mention when describing her. She did not die when cut into seventeen pieces, she had an aversion to consuming human blood and when compared to all other vampires she was strong. So strong in fact that to describe Arcueid Brunestud as simply strong is a disservice, Arcueid was a product of greater beings known as the true ancestors who created her an arbitrary goal. They created her to be stronger than themselves. Why they chose to do this is unknown even to her but what we do know is that they succeeded.

After achieving their seemingly arbitrary goals, the true ancestors found a purpose for their creation. They named her their princess but given the role she served it would be more accurate to describe her as an executor. They kept their princess in a castle far beyond human reach awakening her when they had need of her strength, providing her only the knowledge needed to kill her targets and nothing else. Her targets were any true ancestors who fed on human blood and the monsters created from their victims.

Arcueid was an effective executioner and even as the last true ancestor she pursued the monsters which served as their legacy. Unfortunately after being cut into seventeen pieces by an ordinary high school student she was weakened and forced to enlist his help in slaying her target. The story that followed was a hellish battle for survival which ended with the vampires slain and Arcueid sleeping in a castle far beyond my reach. As far as I know she's still recovering from the injuries I inflicted on her during our first meeting.

It may seem unlikely that a normal high school student could survive such a story, indeed it is difficult to imagine that an immortal vampire could be harmed by a normal person. My ability to perform these feats while notable is not important to the story, for the time being it would be sufficient to say that a long time ago I awoke in hospital to a world covered in lines and dots, if these lines are cut or these dots are stabbed, anything can die.

Having lived a normal life up until recently I rarely thought of this ability, no student needs an ability to commit murders and I have an aversion to taking lives. Because of this I am perhaps understating its involvement in my current predicament. After surviving those perilous weeks alongside Arcueid I died suddenly from the strain of perceiving the world in a way that no human was meant to. My 'Mystic Eyes of Death Perception' brought about my own death.

…This preamble has gone on for quite a long time, to be honest I'm still patiently waiting for the Goddess in front of me to calm down. There is little else to be done in this empty void, it's devoid of anything other than a chair containing a crying goddess and myself. I think she's done crying, It has been a while since I've heard any... she's sleeping.

"Aqua-sama" I hear her shift slightly but she doesn't respond.

"Oi, wake up!" her chair scrapes as she starts at the sudden noise.

"Eh, what's happening here? Why is there a creepy blindfold guy?"

"It's Shiki Tohno and as the Goddess here I think you should be the one answering questions."

This is ridiculous, what is this the plot of a light novel. The idiot goddess in front of me is rambling on about another world which works on RPG mechanics yet somehow she sounds like she's trying to sell me a used car. Ignoring her I take the opportunity to reflect on what she's said up until this point trying to discern something of value. In the last few minutes she's proclaimed heaven a sexless care home and dismissed the cycle of reincarnation as pointless. It's pretty obvious she's pushing me to take her third offer, but I can't say I see the appeal of playing clean-up for this idiot. The mess I'm speaking of is that somehow the goddesses of this other world have managed their domain so poorly that people are refusing to reincarnate into it.

"… And so, all you need to do is to choose a powerful ability or weapon."

I'm brought out of my distracted thoughts by the loud thump of the catalogue she just dropped in front of me. The first page is filled with all kinds of ridiculous weapons and abilities on it, 'God Gun', 'The Blue', 'Gate of Babylon' and all sorts of abilities with names way too specific not to be references. Of course, none of these names seem particularly helpful as I have no idea how they're meant would work.

"Do you know what 'The Blue' is supposed to mean?" How could anyone pick an ability with such vague names?

"Nah ~ hurry up it doesn't matter what you choose, come it can be anything"

After recovering from her previous fit of tears she's returned to that dismissive attitude from before. But well if she really means anything…

"Okay, I choose Arcueid Brunestud"

"Alright. Please don't move away from the centre of the magic circle…"

Wait, did that just work, I've been searching for months and now-

"…What did you just say?"

Ah there it is.

"Arcueid Brunestud, I want to bring her with me."

Hopefully she won't recognise the name, she doesn't exactly seem very well informed so It's unlikely she's even heard of- why is she hyperventilating?

"You… you're the one who… you dated… that one… no. As a goddess I refuse your request"

There is an awkward silence which for once the goddess doesn't feel the need to break, almost a minute passes before I finally respond.

"You shouldn't say things like that after getting someone's hopes up you… fragile goddess."

As I hiss out those last words I slowly raise my blindfold exposing my left eye.

-Thump

Blue Hair and eyes. She's not human.

A light purple hagoromo draped listlessly over her shoulders. She's not human.

Lines and dots cover her like fracture glass. She can die.

-THUMP

The fingertips of my right-hand tremble as they curl around the hilt of a concealed butterfly knife. She's not human.

-THUMP

My brain tells me only one word, I grit my teeth as I try to suppress the impulse.

This goddess. I'm going to-

"Waaaaaaah! He's giving me a creepy look, why, why do I get all the weirdos?"

Crying hysterically the inconsiderate goddess dives behind her chair as though it could somehow protect her. As she moves out of sight the impulse disappears as though a spell were broken. With my thoughts calm again I idly recall hearing that weirdos attract other weirdos. I release an exasperated sigh as I lower the blindfold and try to regain my composure.

"Why won't you bring her here?"

Despite my best efforts I can't suppress the animosity that leaks into my voice, her voice trembles as she sniffs back a sob.

"She can't be brought here, creatures like that can't leave the world they were born into." For once it seems like the goddess is giving a useful response.

"Can you send me back to my world with my memories intact?"

"Only if you defeat the demon king", the demand might have sounded more grandiose if it weren't for her petulant tone. Despite my frustration I take a moment to consider my options, this goddess is presenting me with an opportunity to return to life and with enough creativity I can find a way back to my world.

"Right so you said I can pick anything I want"

"Within reason"

"Can you give me an item that will let me travel to anywhere I want?"

As the words leave my mouth her eyes narrow, it seems she's caught onto my intent, I might have been a bit obvious there.

"How is that going to help you kill the demon king?"

"I get lost easily so I need something to help me find him…" I never was a very good liar.

"Ah makes sense" no it doesn't.

"Shiki Tohno san. You will be heading to another world now and become one of the candidate heroes to defeat the demon king. You will receive a gift from the gods the moment you defeat the demon king."

"This speech sounds rehearsed"

She shoots me a glare before continuing.

"A gift befitting a world saviour… you will be granted a wish, it can be anything you want."

"Why did you say it like that? You already know what I want."

An awkward silence forms between us before I am suddenly thrust into another world, it seems I've spoiled the mood she was going for.

I narrowly avoid what sounds like a carriage travelling over the pavement before I lift my blindfold to take in my surroundings. Houses right out of medieval England and strange looking passer-by who are all giving me a wide berth. Huh, I think I just saw someone with elf ears- oh animal ears this world really is built like a lazy RPG.

I slink into a nearby alleyway before searching my pockets for anything of use. I find my knife, a compass which had not been their before and a note. Examining the compass, I open the metal casing to find a golden needle floating inside a clear orb, surprisingly the lines of death on the item are faded and thin marking the compass as sturdier than the goddess who created it. Flipping open the accompanying note I find detailed instructions on how to use the item written by someone named Eris. Following the instructions, I call out my desired location.

"Millennium Castle Brunestud…" nothing, "the Tohno Estate…" nothing, "next to that wall"

My face is inches away from a wall that a moment ago had been several metres away. I stare at the note again flipping it over to find an additional passage.

P.S. I doubt this will matter but the item's range is limited to the world you are on. I am certain that you did not ask for this artefact with the intention of abandoning this world without slaying the demon king so there should be no issues with this limitation.

Eris

"Ah… clever"

Story won't be finished that quickly I'm afraid. I do plan on bringing Kazuma into the world later but the story will still be told from Shiki's perspective. There was a lot of exposition this chapter, for the most part I'll be looking to get across anything else about Shiki's past without any big infodumps. In case anyone's curious I tried to emulate Nisioisin's writing style during Shiki's retelling of Tsukihime, I thought it might help get it across quickly while conveying Shiki's opinions on his past. So... Did I nail it? Or did I fail it?
