Gestalt Vol. 4 (manga)
Olivier continues his roundabout trek to G, accompanied by Suzu and Sakata. Along the way they meet an old man who offers to aid Olivier in exchange for tutoring his daughter Roxanne. The girl turns out to be much more than she seems, with hidden powers and a history with Ouri as well. With all the various plots starting to come together, Olivier and his friends head back to Salsaroa for some answers--but the real game is just beginning!
