Rin is looking down so Kazuki ask her how she's doing.  She tells him to get ready for an attack when suddenly a man arrives from nowhere and attacks him and Rin.  Kazuki finds out that this was her kando sensei and that she does not like him for the hard work he put her through.  She tells her sensei that she will not go back with him since she is engaged to Kazuki.  Kazuki plays along and her sensei says that he will let her stay if they both can defeat him in week.  What makes things more interesting is that her sensei is an "ahuman" - a wolf man.
