I don't believe the sensei would know about the truth merely what the character knows and before taking on this job they  still sought to see the child cared for so the character would still  tell a positive view of  his birth parents regardless of not being in the characters life. Maybe the sensei went and did some digging on his own but probably has not told the character anything. That was why  I included that part about being a Junior instructor so the character could be sent as representative of the Maburoshi family.<br/><br/>Yes  they are still alive but they are all well past the age of Gempukku so they are already serving the clan and family. So the keep in touch but not as actively in  each other's lives as the once did. They still consider each other like family.<br/><br/>I have not come up yet with names of the parents  of their names as remembers of the crab clan and the names they took on when the  under Musha Shugyo.<br/><br/>Their will also be a Scholarly and Religious  and social Sensei  in the characters life as an Ally. That  handle the teaching of  reading writing and the necessities for a daily life of a samurai beyond fighting. This was the  person that taught  the character  about Theology and  Medicine.  This NPC also discovered the characters Sixth Sense and helped my character  how to hone it and understand it. This Npc serves the Maburoshi family as one who studied under a Kuni sensei when it was discovered this npc could  hear the whispers of the Kami.  So after that the npc returned to  the Maburoshi to be a teacher to ronin that have entered the family but still under Gempukku age.
