☆AU Powers:-

I thought that above is a bit less so here is the additional boost.

By completely gaining control of a familiar, Kojou can call upon it's True name. Like Aries Prote for the first familiar and so on.

This changes kojou's hair color and eye color to match the color theme of the said familiar. He can use their abilities without summoning them on a large scale.

If summoned with a true name, the familiar is more powerful than normal. This power if called Thirdz by Kojou.

☆ Blood Companions/ Servants/ Vassals/ Bonds:-

They are pseudo-vampires that have contact with first generation vampires, primogenitors. They were said to possess combat capability sometimes surpassing that of pureblood vampires and lived with their masters for eternity.

As such, becoming a blood servant to someone of the opposite gender is akin to marriage. It is shown that by having contact with their master, the person can summon their master's beast vassal.

Blood servants are created by 3 ways:

1.) Consuming the blood of the master vampire, i.e the Primogenitor.

2 )Taking a piece of the master's body and wearing it. Like a rings made from the ribs of the Primogenitor by using alchemy.

3 )Repeated biting of the person. This method depends on many things. Like the will power and other things.
