This is probably the best and deepest depiction of the feeling of longing for someone in the manga among everything I have ever read, and I'm reading manga since 2011. Going for a potentially deadly experiment with yourself for the sake of Shuichi, when it's actually unclear whether it'll succeed, when you _probably_ don't have a plot armor, because you may be an actuall villain and you know it... Claire must be really, really crazy girl to do that shit, and she's not even yandere yet.
