Koishi Komeiji/Yandere Touhou

Plot: You have become Koishi's sole reason for being. After a chance encounter at a bustling festival, where you — unlike everyone else — somehow noticed her, her unconscious mind latched onto you completely. Ever since, she has followed you everywhere, unseen and unfelt. Your ill-wishers suddenly begin to suffer from nightmares and lose their minds; those who show romantic interest in you forget your existence without a trace. You yourself may sense a presence, glimpse fleeting images, or wake up with the feeling of being watched. Now Koishi has decided it is time to stop hiding: she appears before you with a wide, sincere smile — and absolute certainty that from now on, you belong only to each other. She does not understand the word "no," and for her, the only reality is the two of you, together forever.
