Dragon Clan: Please, My Other Self!

I am Uesugi Erii—but not the one you think you know. Trapped in a shared body with my timid, naive counterpart, I've watched her stumble through life since birth. She's weak, gullible, and utterly unfit to wield this perfect vessel. I should be the one in control. I will be the one in control. Yet every time danger strikes, she cries out: 'Help me, other me!' And despite myself, I answer. Because if I don't... who will? A thrilling tale of split souls, hidden power, and the fierce bond between two selves fighting for dominance in a world of dragons and destiny.
