A Black Dog's Gratitute

One shot: set after The Missing King. Kuroh was unpacking his stuff in his & Neko base. He came across a forgotten letter & was reminded a vague encounter with a guy who took care of him over a night when he caught a cold. He decided that he had to thank him & decided to look for him. The only clue was only his facial feature. Spoiler for "Memories of Red" & "The Stray Dog".
