Onihime VS

Onihime VS (鬼姫VS, Onihime Vāsasu?, lit. "Demon Princess VS") is a manga series written by Dall-Young Lim and illustrated by Soo-Hyun Lee, both who are known for the Korean manhwa Unbalance Unbalance and the light novel The Phantom King. The series revolves around Setsuna Kashiwagi, a Japanese high school student with a chronic heart problem who inadvertently makes a deal with an Oni for 10 million yen in exchange for his life in a year. He is soon met by Kanna and Rena, two princesses of the Royal Oni Clan who act as bodyguards to protect his heart from other Oni in exchange for one of them eating his heart after the year has passed.

Onihime VS debuted in the special "Hard" issue of Kill Time Communication's male-oriented manga magazine Comic Valkyrie, and began regular serialization in Comic Valkyrie afterwards. The first bound volume was released in Japan on September 30, 2008, and the fourth volume was released on November 2, 2012. The series had a long hiatus from July 27, 2010 to January 27, 2012, resuming serialization in Comic Valkyrie following the finale of Unbalance Unbalance, and ending serialization in the November 2012 issue.
