maybe she landed on yui and killed her that way
Yeah, she's smart enough to do that, it's the obvious way to survive.
So what was Liche's real name if her name is supposed to be based on Beatrice? Either way she ended being my favorite character because she just ticks so many boxes for me. If someone were to define the perfect love interest, Liche's would be pretty close.
Even the author's notes are a single page, I feel bad for the author, would be nice if they published a non-rushed version of the story somewhere else independently.
