You and the Z fighters have a half Namekian and half vampire on your team

You haven't seen Piccolo drink any blood, not yet at least. Every time he would stand out in the sun he wouldn't burn since he had green skin instead of very pale skin, the only things you saw as a vampire traits is his fangs and maybe his cape since vampires wore capes but other than that you just saw regular Namekian features on him

Recently you've been seeing bite marks on your neck that was enough to dig into your flesh and go to your blood which concerned you since you've been noticing the marks on your neck had increased every time you would wake up.

It was eleven o'clock and you woken up due to feeling something on top of you and feeling slight pain from your neck only to find out that Piccolo himself was drinking your blood oblivious to your awakening.

You were confused and slightly mixed with shock, why would he be drinking your blood out of all the people or animals he could drink on..?
