It definitely has an intriguing and creepy vibe from the get go. The story has a good pacing, keep up the good work!
This isn't particularly a problem yet since there's still only one featured character, but it would be better if you keep the 'tails' of the speech balloons, since it clarifies who is speaking what. I also see that you used both Japanese and English onomatopoeia for SFX, and I think it would look more consistent if you just stick to one of them.
I had difficulty understanding a few parts of the story (for example, page 5). Try zooming out of the characters so that we can see more of the backgrounds, where the characters are and where they're heading. I know background sucks for some, but it doesn't have to be complicated! If it's something that isn't particularly important to the story or is really far behind, you can just draw the silhouette of it.
Good luck on your comic
