Seven Arcs Corporation(株式会社セブン・アークスKabushiki kaisha Sebun Aakusu) is a Japanese animation studio established on May 31, 2002 and is located in Nakano, Tokyo, Japan. The company originally produced adult original video animation series under another animation studio named Arcturus since April 2000 and had the intention of eventually producing television anime series, which became possible in May 2002 when Seven Arcs was formed. However, they still produced adult OVAs in the beginning, such as Night Shift Nurses, but in 2004 they produced their first television anime series, Magical Girl Lyrical Nanoha. Since then, the company has produced a number of other television anime series and even an animated movie.
