Despite what a lot of people say about the psychopath known as Kanato, I don't believe that he is a yandere.
I do believe that he has yandere like tendencies, but he is more of a yangire. But who I do think is a yandere is Laito. But despite my own personal opinion, I kind of what to know what others think about the two (in terms of who is more like the yandere stereotypes). If anyone would like to know why I think this, feel free to leave a reply and I will happily tell you!
