Mugetsu was shocked to see a reflection of himself in his mind. He took a step back then circled around the reflection.Incorrect, all upper dantian entities are familiars. A familiar doesn't require sentience, but since we can only create sentient spiritual entities within ourselves or others, they are essentially spiritual familiars.
Correct,
Incorrect, you made me consider a point that I hadn't thought about. I'll explain it in a moment. However, there is no defined way to get rid of a spiritual familiar from an opponent that is not a Hayabusa. For the sake of keeping everything fair, keeping it similar to genjutsu; a full body surge of greater rank would do the trick.
Correct
Explanation of 3rd question
Let's say you use B-rank upper dantian on another Hayabusa. A-rank will prevent the opposing Hayabusa from using A-rank and above spiritual/mental techniques. For Hayabusa this would translate to an inability to use upper dantian Wuji Dao as well.
Alternatively, for Hayabusa, because of our spirituality, we could prevent another Hayabusa's attempt all together through our passive spirituality ability.
"We'll move onto the upper dantian application. This application is a little more complicated than the previous to. We are actually creating sentience without physical form. You need to call upon the chakra in the upper dantian to bring about consciousness from nothingness. This consciousness will have a form but it shall be contained completely within the mind."
Hiroshi closed his eyes and focused on creating, essentially a replica or Mugetsu. He focused on creating the entity within Mugetsu himself such that the child would see a pale white imitation of him with the same exact personality, albeit, slightly calmer. The entity then spoke to Mugetsu.
"Now try doing the same within Hiroshi-san."
Do i really look this skinny?
He fools around for a couple minute until the familiar reminds him again.
Uh... okay then. Lets try it
Mugetsu performs a seal of confrontation and employs upper dantian, but realizes he doesn't understand how to differ between creating something inside someone's mind and a physical being. He takes a minute to think about, and then continues using genjutsu as basis. He employs upper dantian again and tries to fashion a familiar after hiroshi, based on his own knowledge and observations of him.
Did it work? How do i know if it worked?
