07th Expansion (pronounced "Seventh Expansion") is a Japanese doujin group that specializes in the creation of visual novels known as sound novels. They started out drawing expansion packs for the trading card game Leaf Fight, but they are most famous for creating the doujin game series Higurashi When They Cry.

He is also credited as "Partner in Crime" (主犯) in the early credits of Higurashi, possibly owing to Yatazakura influencing Ryukishi's doujin hobby, introducing him to NScripter, and creating the original "scary eyes" that would appear on Higurashi characters.[1]
