Trivia

 * He bares a resemblance in appearance and abilities to Train Heartnet (the significant  difference is that at his gun is written "X" which is different from Train's, which is written "XIII"), the main character from the manga and anime Black Cat, another series by Kentaro Yabuki. Also his name, Black, represents Train's nickname "Black Cat".  Train is also friends with Eve, a character which resembles Yami-chan in both apearance and abilities.
 * A black cat always appears before he does. Whether this cat is his pet or companion for battle has not been revealed.
 * In Episode 10 of To Love-Ru Darkness, while Golden Darkness is talking about the Organization, in a flashback there is a silhouette which is extremely similar to Black.
