Altair (アルタイル Arutairu?), also known as Military Uniform Princess, is the primary antagonist of the anime series Re:Creators and the secondary and penultimate creation of Setsuna Shimazaki before her suicide, based on Shirotsumekusa (シロツメクサ) from social game Eternal Wars Megalosphere (悠久大戦メガロスフィア Yūkyū Taisen Megarosufia). Her real name was revealed to be "Altair" and she came from an online music video called Altair: World Étude. An independent existence without a story. She is responsible for bringing the Created into the real world. Her plan is to make the worlds collide by getting the characters she brought into the real world to fight thereby causing the destruction of the rationality of the real world, and to ultimately bring about great destruction and cause everything to return to oblivion. An in-depth explanation and analysis on Altair is given here
