I really need a manga to read! I'd like the ones that are short (under 30 chapters) and has got good art style. My preferred genres are:

• Slice of life. If it contains a touch of romance it's okay, but I don't want too much and cliche romance. I'd love the ones that take place in school! Similar manga: Orange (Takano Ichigo)

• Horror. I've read almost all Itou Junji's works, so don't recommend me his manga anymore, please. I prefer the ones that are actually scary, has got some gore and just..haunting. Similar manga: Uzumaki (Itou Junji), Fuan no Tane (Nakayama Masaaki)

Thank you very much, I appreciate every single replies!!
