Hi! It most certainly is a horror thing. But I am not going to read it all.
Story: The pacing of this is so fast you go from point A to point B in two pages. I read very slow, so don't think that I am saying this because I am zooming through your work. Hm...one thing I dislike is that the main character is so casual with everything that is going on around him. Let me say here, I was raised Catholic and have a fascination with exorcisms. I'm not as familiar with Shinto exorcism and house cleansing, but I feel like all of this is very easy for the two of them. Yes. I realize that your character should, for all tense of purposes, be able to perform these things. However, he is still a young man and she is a young woman!
Art: I love the lack of color. For horror comics, it is pretty much required in order to build up a dark atmosphere. (I'm saying that and a million color artists are going to come in through my window and eat my cat) I like that you separate each chapter with a picture so that we can SEE that the chapter has changed. I don't think this is something commonly done in American comics, but it is done in manga. I can tell that you have put a lot of time and effort into designing this, the characters, the world, etc. IT REALLY SHOWS. I can see that it isn't done, but keep up this good work! I like the different font you use later on in the comic. I think you should stick with that.
Dialog: I want to add this for your comic because you are using honorifics. You use "Name-san" for the demon kid. I think this is fine for your main character because she still respects him, however other students DO NOT. I wish you had used something else for them to call him, like yĹŤgisha, when they are not speaking to him directly. (When I looked it up because I wanted a "meaner" honorific, this seemed perfect to me.) Now I'm not Japanese, but I am fluent in Chinese so please take this advice with a gigantic grain of salt. This is totally personal to me, and -san is perfectly fine. Really. It is a nice touch to give the comic authenticity!
You have put dialog in every single panel I have read from chapter one to chapter four. I decided to skip to random chapters after that because in one sitting, reading all of that much dialog was overbearing. I'm just not used to it in a horror comic/manga. I think over these next couple days, I will continue to read through and and comment how much I like certain parts.
Overall, I think this is a nice comic. I can see the hard work you put into it, and I hope you're really proud of it. I would be. c:
