Not quite. If you are defeated in combat by the final boss, and you have lost to the bosses in the second and third floors, if you lose enough times, endure the sex enough time (use the log speed set up item in the inventory to speed the log, the best number is 5) and while fighting Ayaka's baby demons, you keep enduring and rising until you beat them, instead of just giving up, losing one more time against the enemies in the third floor triggers her Awakening (you may need to endure more sex, though, the game wasn't clear on that and I didn't want to risk it, so I let her "enjoy" the sex).
Her magic remains still weak as fuck, and dark typed instead of holy, and she still has all her fobias... but she becomes a physical powerhouse to the n-th degree. And with that I mean the regular attack becomes the strongest attack in the game, boss attacks included, hitting 3 times for 3-4K damage EACH... and around 15K per hit on a crit in the final boss. She also tanks most hits like their are tickles, and the ones that actually hurt her (after having an orgams in combat, something easy to happen with so many traumas and weakneses)... well, now she has more than 5K hp, I wish good luck for any group of enemies to actually defeat her unless the player is trying to lose. Fear the Saint Fist's Gorlla mode XDDDD (no joke, it is actually called Gorilla mode, and the description in the corruption diary calls her now the Saint Fist)
I'd give the exact numbers, or at least an idea of how much time and how many loses, but the game isn't clear on them, as it depends on what she has endured so far, and I didn't thought about counting the numbers of time my Ayaka was defeated. Also, no clue if it's faster with more or with less weaknesses either, and I probably overdid it anyway, because I wasn't sure how much time she needed to endure the sex, so I let the game do the thing while I went to have dinner and read a book, I probably left it 20 minutes but I doubt you need that much time.
Edit: Oh, and the battle themes become metal versions. The game goes HARD on how powerful she is once she awakens XD
