Talk:Rafael's playthrough - Aka's route/@comment-5.66.33.34-20160701035611/@comment-28788537-20160701052928

It should be letting you fight in the Fight Club. Mechanically, how it works is you start Aka's route with a -20% heath regeneration. In this state, you cannot fight in the Fight Club. At the beginning of the route, you should talk to Robin in the tunnels. She'll apply energy from the armor, which will reduce that penalty to -10%. At this point, you should now be able to participate in the Fight Club, but it isn't recommended. Later, you'll get a sex scene with the armor, which doesn't actually reduce the negative regeneration (it does have an effect, but not anything you'd notice). After that, Robin will preform a partial transformation of Aka, which will reduce the health regeneration to -5%. That's the best you're going to get.

Based on what you are saying, you seem to be stuck in the starting state. If you've gotten the scene with the armor, that shouldn't be the case. Did you talk to Robin at the beginning of the route and get the blast of energy? It's possible that if you skipped that scene, it could mess up the rest of that quest. Other than that, I'm not sure what's going on.
