Eileen Belserion's Father made peace and unite the tribes in his kingdom to prevent war and to share goods and resources abundantly with commoners living peacefully until his Majesty's death. His daughter, Eileen, ascended to the throne but didn't reign triumphantly as her father did, leaving the neighboring tribes to plot against her in secret. Years had passed and a new scion was brought to them. The ravishing princess grew up inside the kingdom giving no permission to leave. Erza Scarlet, now a 16 year-old princess of Belserion Kingdom will carry on the liabilities in the near future of each tribe with the help of her noble/childhood/best friends; Lady Mirajane Strauss from Earth Tribe. Lord Laxus Dreyar from Thunder Tribe. Jellal Fernandes from Sky Tribe. However, it seems like its not only about the tribes but rather in the human world as well. A quest was given to her childhood friends leaving her behind. After several years, where the Majesty's death is near, she was given the quest to go after them to find the answers to deep and dark secrets of her Mother.
