Protected by his special diplomatic rights, the police could not proceed with action against him.
On the other hand, a talented pianist, Nina, from West Gariera shows up at Cat's Eye Cafe with a request, looking for a father whom she has not seen before or know his name. It turns out that he is no other than Helzen. Things get complicated when Nina's grandfather cum manager abducts him and Ryo offers to help. As things get confrontational among men, Nina's performance reaches its climax...
