Or the anime went out of their way to censor the obvious fatal wound that Ikaruga suffered and then wrote her off as having survived because having her die right after they showed Simon get murdered was too much. I always thought she died in the manga after this, and Neinhart kind of affirms this with the fatal wound she suffered and then the tower collapsing not long after.
