Byakuren is a bit of a pacifist but she will defend herself if provoked. Either way, she's a very good sport about being tied since it's one of her secret personal hobbies when she wants to get away from her temple for a little while. Her long hair and wonderful body allow for a good variety of ties based on her outfit. If she's wearing her usual one, bind her in a way that emphasizes her legs. If she's wearing something other than a skirt, bind her in a way to emphasize her chest. Her chest and her hips are her weak spots, so enjoy them no matter how she's tied. Her hair color is unique among all of the girls, so always give her a gag that turns the focus to it. So long as one remains on her good side, she will always remain very friendly.
