Nijikon 

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.

nijikon 

The feeling or opinion that two-dimensional anime, manga or game characters are more attractive (visually, physically or emotionally) than real-life people (from the English "2D complex".)

Can you believe nijikon want to legalise marriage with fictional characters? That's totally ridiculous.
