Nijikon (二次コン) or nijigen konpurekkusu (二次元コンプレックス), from English "2D complex", is a Japanese term that appeared
in the early 1980s used to describe the affective perception that two-dimensional anime, manga, and light novel characters are more
attractive visually, physically or emotionally than people from
the real world.
Nijikon can be expressed, to some degree, as a genuine
sexual orientation in which the person loses interest in real-life people but develop feelings of love and
sentimental attachment to two-dimensional characters.12 They are generally attracted to the behavior and
exaggerated physical or facial features of the anime/manga art style, which are perceived to be "ideal" human features.
