My thought was ignited by Tsubasa Reservoir Chronicle episode 21, where syaoran becomes an oni slayer apprentice and meet Seishirou, his martial art teacher.
In fact, Seishirou is not only a teacher. He is one of the most respected by Syaoran. But this time, he is a new breed oni, not his teacher, although his memories remains.
Question then posed to Syaoran: Would he go far by fighting against his teacher? Would he forget all the teaching he got for the feather of Sakura?
Even after the episode was done I was still thinking about the same question. How far can we go to reach our destination?
In episode 21 Syaoran indicates that he would even go against his teacher to gain back Sakura's feather.
If you are in the same position, would you? (go against your teacher for what you believe)
