Lambert

The Imperial Knights from Tales of Vesperia have under their control, a bunch of "War dogs" that help them in combat. Lambert, and his son Repede, are both some of those dogs. Niren is Lambert's caretaker much as Yuri is to Repede. Lambert is a good father to Repede and it shows after Lambert is gone. Repede comes running out to greet Yuri but then realizes that Lambert isn't with him.
