Ezra's manga / #curse(2)

kannagi (uke) has to fight the sea monsters every night to keep the island safe. Every time he fights, he gets stained by the ocean and slowly dies just like every other kannagi on the island. As a child he meets another Child that lost his mother (seme) and the seme falls in love with the kannagi and they spend 8plus years together. Slowly they realize that the monastery giving all the orders to keep fighting is wrong and that the seme can heal the stains of the kannagi because he is the the prince of the ocean spirits (his father possessed a human and had a child (seme) and their main goal is to take all the ocean spirits and possess humans and since the seme is the prince they are counting on him).
