Setsuna

 (セツナ Setsuna) is the deuteragonist and one of the playable Characters in I Am Setsuna.

History
A girl who bears the fate of heading to the land of distant ends as a sacrifice. She has no hesitation about offering herself as a sacrifice for the sake of the island's people. She is honest and pure. She is a kind person, so much that even now on her dangerous journey, worries about her guardians more than herself. However, her faith to accomplish her destiny as a sacrifice is stronger than anything else. Her mother was Mana, who had left Setsuna with Raishin. Setsuna believed Raishin was her true father, although Nidr was the real one. This is revealed in the Ruin, where Nidr suddenly was called by his past self.

Etymology
The meaning of the Japanese unisex name “Setsuna” is: “Calm snow”.

When defeated in combat Setsuna says "Okaasan, gomennasai." which translates to "Mother, I'm sorry."
