Katabasis: The Manor in the Darkness

One moment Akari is loving her life as a member of an idol group, and the next she finds herself waking up in a baffling manor house she's never seen before. The manor seems to have no exit and the rooms shift and change as you move through them, and the only other being present is an equally baffling man who seems like someone out of an isekai story. And to top it all off, there appear to be only two ways to regain her memories of how and why she came to be here: Drinking the blood of this strange man, or sleeping with him!?

Follow Akari down the rabbit hole and see what there is to find in this enigmatic tale…
