Also known as: 感情×人外, 感情誰デザイン
An Artist Collaboration character design event hosted by Nt Rum on Twitter, participated by 22 artists including the organizer. The artists would create an Original character according to the theme, then make a fanart of another artist’s character (also designed during the event) while the same happened to theirs.
The event’s name translates into "Emotions x Non-Human".
