Misaka 13577

Misaka 13577 (ミサカ13577号) was a Misaka clone that appears in Toaru Majutsu no Index. Originally supposed to be killed in the experiment against Accelerator as part of the Level 6 Shift, she was one of the few that remained in Academy City for readjustments.

The morning before Vento of the Front's attack on Academy City, Heaven Canceler is seen talking with the sisters regarding separate measurements for them, Misaka 10032, Misaka 13577, and Misaka 10039 agree that they only need to take one set of measurements since they share the same genes. However, they discover that Misaka 19090 has been dieting in secret, due to Heaven Canceler's suggestion that men, and possibly a certain high school boy, like slender women. Misaka 19090 attempts to get away, but the other clones jump on her.
