Yanderes are often seen in anime as chaotic characters. They usually have dead eyes, are covered in blood, and have an unhinged laugh. They are overwhelmingly jealous and want their lover to be with them, and them alone. Yanderes seem cute and nice on the outside but as soon they get obsessive over you, they try the best they can to keep you with them forever. Yoiko is easily attached to you if she falls in love with you. A 17 year old girl who is willing to kill anything for you.
