07th Expansion

07th Expansion started off producing original cards for the trading card game called Leaf Fight as a way to present their work, selling their works at various events including Comiket, where they met BT, who later became the manager of their homepage.

After two years of selling cards, they began thinking about switching to another genre. During this time, Tsukihime by Type Moon rose in popularity, opening the door for many aspiring doujin circles like 07th Expansion as co-founder Yatazakura began learning how to use NScripter. Along with Ryukishi07, they began attempting to make a visual novel using a scrapped stage play written by Ryukishi07 called Hinamizawa Bus Stop as the main part, later turning into their first work Higurashi When They Cry.

• Ryukishi07: Founder of 07th Expansion. He began drawing manga in Junior High School to express his creativity. In high school, he started to notice the difference in artistic abilities with his peers, leading him to quit drawing manga. During this time, he became interested in doujin activities, however, due to not having his own circle, he would help out other doujin circles with coloring illustrations. Later studied at a vocational school.
• Yatazakura: Co-founder of 07th Expansion. Inspired by Tsukihime, he learned how to use NScripter which led to the creation of Higurashi When They Cry with Ryukishi07.
• BT: Homepage manager. Initially a customer while 07th Expansion was producing cards for Leaf Fight. Later died in 2009 from an illness.

Rena Ryukishi is the company mascot. At first, she was wearing something resembling armor before changing to a uniform in the style of Pia Carro.
