Kurogane looks like Fai's disgruntled guard dog in that picture. Fai looks like he could just reach over and pat him on the head.
Doesn't he just?
That's so cute! When I saw it I just thought: "Well Kuro-tan, I hope you realize WHY Fay calls you his 'big doggy.' "
Thank you so much for the scans Mela, and thank you too Fynn, for posting those images.
