This is an Allen Walker bromide from "D.Gray-man Bromide: Black Order Secret File 02." The first photo shows the bromide with the card backing opened. The second photo shows the "Meeting Room Card" (which features the characters commenting on the bromide content). The third and fourth photos show the card backing closed. I have kept it with care, but it is over 10 years old, so there are some stains. (Photos 5 and 6) D.Gray-man, D.Gray
