― Before I became the original sin of Sesa, Sesa was already my long-standing mistake. Iel, blessed with innate divine power to the extent that she was called the grace of Misty, was making a name for herself in the non-imperial kingdom when she received the order to neutralize the magic of Princess Sesa. After meeting Sesa in the imperial palace, Iel gradually begins to feel love for her, but as Sesa's magic improves, she starts to distance herself from Iel. Iel is willing to fight on the battlefield for Sesa, but for reasons unknown, she is pushed to the battleground of Valen, and begins to harbor mixed feelings of love and resentment towards the Sesa she once loved so dearly. Ultimately, Iel decides to escape from Sesa, and while evading her pursuit, she falls into the sea with Sesa, returning to her childhood past.
