Comprehensive Manga: Daily Life Starting from Yanghai Academy

My name is Yuuto Kasahara, and I am a time traveler. I study in a school called Yokai Academy.... Among my classmates are a vampire named Akaya Moeka, a half-demon named Nara Rikuo, the human spokesperson of Death, Kurosaki Ichigo, and the eldest daughter from the Rei family, Dojun... This world is very unstable, with unknown monsters attacking, great monsters destroying the world, and even gods from myths and legends coming to cause trouble from time to time! Oh, by the way, I am not an ordinary person. I can analyze the abilities of my classmates and even monsters and use them for my own purposes. Later, in order to facilitate my own analysis and protect mankind at the same time, everyone and I founded an organization called the SCP Foundation.
