Unicorns are people that obsess over their oshi's purity to such an absurd degree they will instantly turn into their biggest anti if they should ever become "impure" in their eyes. It's an old idol otaku term that's been used in that exact same way for long before most people in this thread were even born.
They are quite literally named "unicorns" anon, the mythological beast that only shows up infront of the purest virgin maidens and form a bond giving eternal youth and beauty to them. If the maiden should ever become impure the unicorn's horn will split in two and the resulting bicorn will first gore her before become a raging beast and destroying everything in its vicinity before dying itself.
