[Tachibana]

Spoiler for Tsukune:

Ok, remember when Tsukune got his first injection of the Vamp/Shinso blood when they were fighting Kuyou from Ura-Moka, the next day him and Omote-Moka thought he turned into a vampire until Ura-Moka noticed that they were misunderstanding the situation and then explained that infusing Tsukune with the Vamp/Shinso blood made him a vampire, but only for a few moments until the blood's power is used up and he reverted to normal to which the blood became completely useless in his body.

But it was the Shinso blood that Ura-Moka and Omote-Moka actually gave Tsukune and since this blood is the most potent in the R+V universe, it's power didn't run out like the normal vampire blood's power did, but was inactive for the time being and then became active once again with the new injection of Shinso blood in his body, i was thinking that Ura-Moka was also misunderstanding what her blood was doing to Tsukune, since she thought it was normal vampire blood that she was giving him, when it was actually Shinso blood.

I'm not really going anywhere with this, it's something i thought about recently...

Back on topic, i think aside the pale skin, fangs and silver hair, the idea of Tsukune having permanent vampire eyes like Ura-Moka would be great, he has always had them before in his transformations, no reason to take him away now, i think all he would need is a seal like Moka's to hide his Shinso form once the transformation was complete, of course he would have the vampire eyes anyway but they would only show themselves when he is serious, this is common amoung all vampire's in R+V, including Akasha and Ura-Moka, we rarely see this with Ura-Moka the only time we see her with normal eyes was in her childhood.
