Context: During the whole Blue Archive vs Project KV dramas, a joke spawned from the Korean internet community about how KV would be more popular if it has futanari cockfight instead of sword fighting. This is a pun based on Korean slang "kochu" (sword) and "valgi" (sword drawing), which is used for penis and erection, respectively.

As a result, this caused both Korean and Japanese artist to draw tons of KV futa fanarts, usually to make fun of the game. This also explains plothera of other futa KV posts currently on Danbooru.
