Shun is the father of Bakula and Chiyo. He is very silent and rarely speaks to others, well with the exception of his kids and his Yasu. When the two first met, Shun was originally suppose to assassinate her, though for the first time in his life he couldn't. He felt the need to get to know her and he wanted to love her. Yasu was cautious about him at first, she knew nothing about this bunny with usual eyes. Though time does change things, her feelings for Shun change as well. Shin and her went on May missions and dates. She would impress him with her spells which allow her to see a genuine smile. As for Shun, he told her about his work as an assassin and how he was suppose to kill her. This did lead to some time apart, though only for a few months. Yasu went against her father word and reunited with Shun. Shun then married her and had his beautiful daughters. He has to get one of his assassin pal, Koji to get a blood transfusion for Bakula which have her the python DNA. Shin is more of a mentor to his kids, though he will get rid of anyone that hurts them. Quite literally. After all, old habits are hard to get rid of.
