[Tachibana]

Spoiler for 38:

I agree, i have no doubt in my mind that Alucard will be involved as our original theory that he is the final boss and that Hokuto and Kiria are going to be responsible for this.

Now that i think about it Tsukune appears to be taking on the traits of all three Dark Lords.

Akasha Bloodriver = Her Shinso blood through Moka.
Tenmei Mikogami = The Holy Lock and youki control training.
Touhou Fuhai = His training and the Jigen-Tou teachings to combat Akua.

I think i'll drop the theory that Moka could have given all her Shinso blood to Tsukune. i'll also agree with you that Moka didn't give all her Shinso blood (originally Akasha's), but only enough to make him into a new Shinso.

Perhaps Ikeda is putting Tsukune through all this to prepare for "that" battle unknowingly, what do you think about this?
