As was rereading the manga something caught my attention, in chapter 18 of Season II on page 30 Runy has said that
How he has become Tsukune is ... already able to feel things normal humans can't
What do you think she meant by that statement, that Tsukune has become able to sense youkai aura, or has she meant something else ??
Also in the next page she says that
He's at least still human though .. well she could mean that Tsukune has still got his humanity intact ( that his heart is still human ) becuase I don't think we can call Tsukune ( physically ) a human, well he's at least partially human .... but connected with what was said before, maybe she means that Tsukune's "transformation" has reached another step ... or I could be reading too much into it
