The Dreaming
Although it's a horror manga, it's actually not very scary. It just leaves you a little unsettled and wanting to know what is the mystery behind the boarding school. No jumpscares or anything, which I like. I usually avoid the horror genre but this one was a pleasant read.
Ayashi no Ceres
One of the worst things written by Yuu Watase. She must be off her rocker thinking this is one of her masterpieces. She thinks she's subverted the romance trope and made the series mature and difficult to understand or a conversation-starter... Please, get over yourself. It's none of those and the scientific stuff was so wishy-washy and unnecessary. She needs to get off her high horse, seeing as she can't write proper romance for shit.
