The Demon of the Sparkling Blue Sea

In the past, you lived in a dark space and refused to grow; in the future, even if you become a siren in the world, where the sun cannot shine, the world will still be black and white, and you will still be fragile, unable to withstand a wave, and easily swallowed by the sea. Siren, please use all your strength to break free from the shackles of your spirit. Only by standing with your sword in hand, those mysterious powers that repeatedly leave you ignorant and incompetent will not be able to control your life. The Sea of ​​Demons is the starting point of the battle. The sea monster is your destiny!
