Clans all over Tokyo wait for this time. The Clan War. A ritual commissioned by the Tokyo Clan Society every 25 years. A ritual in which every Clan in Tokyo fights for the title of the greatest and strongest Clan in Tokyo, by having the Clan heirs take part in it as their representative. Saotome Kuro is also part of this War and will do all that he has, to claim his Clan as the greatest. Did I also mention that he has to deal with having an arranged marriage and he can't stand his appointed fiancee? Enjoy this mix of Shounen and Shoujo.
