I had a strange idea on how Moka is going to woken up.
The solution is simple ,... maybe Moka is going to awaken after she had been given a kiss from her "prince" (Tsukune)
...
Though said "prince" is probably going to be killed by a combination attack from Moka and Akua ... soon after, doing something like that ... but, at least Tsukune is going to "die" with a pretty content face ... so doing something like claiming Moka's lips ... while she is still asleep ... might be worth the risk ...
Seriously, though I think that if Moka doesn't wake up, when Tsukune, Mizoe, Kurumu and Tohou Fuhai ... get out of the seal ... and return to their bodies ... then it might be possible that Tsuikune accidentally is going to use his blood connection (the mental connection that Tsukune and Moka share with each other) to reach Moka's consciousness within the Rosario ... to wake Moka up ... after all, Tsukune already did something like that, when Moka was being controlled by Mako (the Outcast Ayashi women, that has been disguising as a nurse) and Tsukune's voice caused Inner Moka to awaken, since removing the Rosario proved to be ineffective.
So, it might be possible .. that if Moka doesn't wake up ... along with Tsukune and the others ... Tsukune might do something similar to what he did ... during the Outcast Ayashi arc in the first season ... and cause Moka to "awaken" from within the Rosario, where Inner Moka's consciousness is probably currently located ...
After with Akua being just a few steps away from Moka, it's not like she can "sleep" in this situation ... which is pretty serious, since even if Ling - Ling has been "created" by Tohou Fuhai ... after thinking about it for a while ... it's not like a ... pretty powerful zombie (after all retaining her own personality, is probably signifying that Ling Ling is signifying that Ling Ling isn't an ordinary zombie), but I don't think she's able to compete against a serious vampire ... so it might be possible that sooner or later Tsukune and Moka would have to enter the fight against Akua ,,, as well ...
