Also known as: 嫉妬, やきもち, 嫉妒
The feeling of being possessive of another person, and feeling fear or anxiety of losing them to someone else, or being envious of their affections towards someone else. Often experienced by Yandere characters.
Not to be confused with Envy, which is the desire to possess something that someone else has, rather than the desire to possess the person themselves.
Touhou artists often use Paru Paru as the sound effect for jealousy, after Mizuhashi Parsee.
