There's a high chance, I saw a poster where Tiera is infront of Marimo.. its kind of shows like Marimo is an aura/soul instead of a real person.. I also read spoilers that states Marino's souls resided in Tiera but some says Shin ended up with schee..
Im still reading the novel, im not that far from the manga so im not sure if these are all correct info.
Is it possible that tiera is like an incarnation/ descendant of marimo. Like she give out that she is something but she is not aware of it. Or maybe she is a forgotten princess ??? Hmm.
