I Love Killing in My Dreams [Crossover]

[Abandoned. I'll see if I can find a platform suited to crossover stories.] She transmigrates through the Spiral's primordial dream and arrives in a medieval world where black and white are hard to tell apart. Gods and demons are indistinguishable. Who woke her from the deepest part of her dream? Where does the Spiral's red thread lead? Some 215: That's how it is. I just want to sleep. Don't bother me. Unless you're pretty and well-behaved, in which case I'll cut you down without a second thought. Some handsome, white-haired man: Overpowered big sis, I'm in! Look at me, will you? Some sleeping heroine: I'm going to sleep. If anything comes up, contact me. I'm leaving my newly adopted sweet little sister and this trash country in your hands for now. Some handsome, white-haired man: Could you deal with this person for me first, big sis? Some enemy: ??? Some muscular, black-haired man: ...? Could you try cutting the Beherit? Yeah, that ugly thing. Some red egg: Sob sob sob. Some handsome, white-haired man: Are you awake, big sis? Can you look at me? My foot hurts so much, sob sob sob. Some 215: Kid, you probably don't know this, but I used to split into multiple personalities in my dreams to kill... to kill people. I wrote this for my own enjoyment, and may revise it drastically at any time. No guarantees on the writing. I'll revise anything that bothers me, and OOC is practically guaranteed. Feel free to say whatever you like, but keep it civil. Griffith goes after Ryougi Shiki. Didn't expect that, did you? You could also think of it as a girlfriend story with a heroine wearing Ryougi Shiki's skin. More details later. The Garden of Sinners/FGO + Berserk. Those are the only two for now. What else I'll cross over with later depends on my mood. I might just abandon it. Update: 2019.06.05: It's Root Shiki after all. 2019.06.14: Studying for finals. 2019.07.30: Abandoned. I originally planned to come back and clean up the rough parts I'd written, but it turns out I need Moon Stones. This is an alt account, so I don't have any...
