To Uchiha Yan's surprise, Haruka was a medical ninja, which might be of some help with his upcoming plans.
Along the way, Haruka rarely spoke. Most of the talking was between Hizashi and Uchiha Yan.
After several days together, even Hizashi no longer wanted to talk to Uchiha Yan, leaving Uchiha Yan deeply disgruntled.
