Phase Three of the Sekirei Project starts now. The first round? A three-way, free-for-all treasure hunt for the most mysterious prize of all-a "Jinki." As Team Minato watches anxiously from the sidelines, Seo and his girls are up against the heavy hitters of the West and South. Nishi Sanada of the West is a rough-riding punk who'll do anything for his lovely Sekirei, while Mikogami of the South is his polar opposite: a spoiled rich boy who treats everything like a game-one he plans to win. Vastly outnumbered, Seo himself enters the fray...! But is a mano a mano fight with Sanada really the way to end this?! And just what are these Jinki, anyway...?
