Victoria of Many Faces, Vol. 3 (manga)

Even after taking down an assassin at the soiree and fending off the prince's curiosity, the next challenge Victoria faces might be her greatest yet- being separated from Nonna. After a Baron insists on adopting Nonna despite Victoria's objections, Nonna agrees to go with him. The pair's bond will be tested as Nonna sees what life away from Victoria is like. And while Jeffrey and the others offer their support, will it be enough to ease the pain in Victoria's heart.
