This is a pretty typical splatter-revenge horror manga. The story is nothing special, it's about four adults on a school reunion to celebrate the 16-year anniversary of the death of their classmate, the titular character, Kiriko. Then, that same girl begins to pick them off one-by-one in orderly fashion. It's pretty straightforward and I was really trying hard to like it, but I just felt bored throughout its entirety. The art was fine. I was just unimpressed with the gore, and the monster didn't look that scary to me. But the gory scenes do have a considerable amount of detail and may look cool to a general audience. I guess I was expecting something more than that. Because I wasn't shocked or disgusted one bit. The fact that this is also supposed to be about revenge from what the adults did to Kiriko in the past didn't do it for me either. It's filled with cliches and it's just so predictable. The characters are also far from interesting, and the story moves in such a predictable way (except for the last chapter).The last two chapters is where it gets interesting but the twist at the end was expected from a mile away. I'm just disappointed more on how absurd and generic it was rather than being scared by what it had to offer. The only real reason I read through the end at this point was to find out why Kiriko died, and the revelation one of the main characters had concerning that was neat. Everything else though was unremarkable. If you're only reading this for the gore, then this might be for you. Other than that, I personally wouldn't recommend it, but check it out and see for yourself. There might be something you'll like.
