Well, I can't do anything about it, since despite me thinking that Tsukune is going to look more human like in his final form, he's still looking pretty cool in his current one as well
Regarding the needless, while I agree that planting the 109 needle might not be everything that needs to be done, to return Tsukune back to normal, I still believe it's a necessary step for Tsukune to get back to his normal state...
After all, let's not forget that after this training arc is over, Tsukune is still going to need to fight with Akua, and if he weren't capable of defending against the Jigen-tou at that point, then the current developments wouldn't make a lot of sense...
Meaning that Tsukune still has to "learn" how to defend against the Jigen-tou and, even if things aren't going as planned, I still believe that the modification ritual is going to be completed, to allow Tsukune to defend against the Jigen-tou.
I think that Tsukune's transformation occurred at this point, to "stabilize" Tsukune's body and bring his other attributes closer to Akua's level... even if it involves Tsukune going out of control for some time...
Of course, I don't think that Tsukune is going to be able to fully control his powers yet, meaning that they are probably going to need to be limited in some way again, but since Tsukune probably won't be restricted by the Holy Lock anymore, after he regains control over his body, I think that Tsukune is going to be capable of using a much higher extent his abilities, then he was before... his body transformation.
