3 Angels of the 5th

The three-woman team from the 5th Special Fire Brigade, known as "Three" despite having more than three members, a point that is humorously noted in the story. They are primarily made up of second and third generation ability users, and are known for using techniques with conspicuously numerous numbers in their names, such as "5th Angels 3 3on3 Three-Piece Slasher ver2.3".

They encountered their doppelgängers during a great disaster and perished.
