De los 3 que mencionaste, solo vi Okami Shojo to Kuro Oji y comparto tu misma opinión, la terminé de ver porque ya faltaba poco y a ver si había una evolución de la protagonista pero que va, decepción total. 😕

Of the 3 you mentioned, I only saw Okami Shojo to Kuro Oji and I share your same opinion, I finished watching it because it was almost over and to see if there was an evolution of the protagonist but what a total disappointment. 😕
