He doesn't notice anything suspicious so decides to retreat to a nearby rooftop and observe from a far. The clan members receive an anonymous message containing a picture of kiryu spying on them. They go to the rooftop to apprehend the spy. Kiryu defeats them and the two parties mutually agree to forget the incident. Outside the HQ, Kiryu realises he is being followed and leads his pursuers into a nearby parking lot, where he discovers the message was sent to the Seiryu by the Watase Family.
