Sanity System

Having mysteriously transported into a world full of mysterious beings, ranging from normal humans like himself, all the way to eldritch abomination whom somehow do not want to devour him. He was granted a gift, a system of sort that lets its user identify any being or object it sets its eyes upon, and despite this seemingly unique ability, he finds himself overwhelmed with the amount of disadvantages he has against stronger beings. While it may seem really versatile at first, it appears that he can only gain basic information on said beings, not to mention, all that did was just give him a simple rundown on how weak he is compared to everything else around him. Beings who are capable of manipulating fire to an utmost limit, to the point they are able to burn from the inside by merely gazing at you, to the being that are able to completely erase his mind, making him a slave under them. Having no other choice but to flee, Ain is met with various obstacles in his way. And the most troublesome being, is his Sanity meter. It wasn't like anything else, and its name was quite deceptive. He wasn't actually sure if it truly had anything to do with ones own sanity, but rather, it seems that it is able to directly manipulate the world around him. And the less Sanity he has, the more "the world shows its true colors", at least, that's what the system told him. And in order to lower your Sanity level? Simple. By killing yourself, killing peaceful, intelligent beings, or by dying in the hands of others. Or, of course, by being horrified to the point that your sanity reduces. The problem arises with the fact that he cannot understand anyone if his Sanity level goes below 100, and it goes below that A LOT. As such, communication and reading is virtually impossible, and the only thing he can do is simply hide, and find a way to increase this darned Sanity level.
