Kind of disappointing this isn't a sequel of the previous chapter, but it's still good. Another creative use of alternate dimensions. I hope Oshikiri finally moves from that haunted mansion after this.
I love this volume. Sure, the first two chapters are kind of lackluster (and disconnected from the rest even), but the rest are all just so good. Wish Itou made more Oshikiri stories, or maybe even a long series! Though thinking it twice, seeing at how Itou's long series tend to be, better letting it at this.
Great: Penpal, Further Tales of Oshikiri
Good: Intruder, Walls
Okay: Hallucinations
Bad: Bog of the Living Dead
