Kataro just discovered he is vampire royalty, now that the servants unlocked his powers they start. training him. They start with the family martial arts, the martial arts of the family are quick, efficient and sturdy it changes depending on the individual fighting style of family members.He gets a crash course in the family martial arts and they teach him how to develop his fighting style.
Its very necessary you never know what or when something will happen. So for a month they teach him (beat him) well as he starts to get everything down. By the end of it all he was tired and sore.The next month was him fighting all the different warriors in the family. He'd fight someone of similar level to him one day, the next he'd fight an intermediate fighter and so on. Like this Kataro gets fighting experience Jiro didn't teach him how to fight as he still sees him as a little boy. As he fights he finds that he likes it, it just feels right he finds his fighting style to his liking and satisfactorily good.
The last month was for getting his powers down, especially the basics starting with fire. Fire is what the Youngbloods are known for and this is partially correct, the other part is being able to blend their power with their fighting style. This style can be deadly or cause people to go insane the reason they figured out many ways to use their power like creating illusions in battle. The ones teaching is very traditional he just feels awkward being called prince. In between all this he had servant come bring things related to the protection of the Special Zone.
They were saying stuff like Prince Kataro please look at these schedules for patrol. In order to do this well he needed to actually look around the Special Zone to see where patrols were needed, and what times they were needed. Which is hard to do between beatings cough trainings but hey he managed. Now that his big cousin is coming back he is over joyed happiness all around and now he sleeps.
