In a faraway country, there is a place where land and sea are connected by a legend. It is said that, when the time comes and you've lost all hope, a Lemuri will contact you and grant you powers. In exchange, you must give him your life on earth so he can escape the sea. Giving one's life for some unknown powers, however... what is the catch behind it? Amita is a faraway island with a bustling town where "clans" vie for dominance, influence and status. Strange phenomena occur; the air itself has an enticing air, keeping people from leaving despite everything. After being away for quite some time, Seira returns to the island she calls home and re-encounters her childhood friend Rio. Soon after, a chain of events unfolds that might make things quickly spiral out of control...
