I recently finished Wartribe Academy after chipping away at it for awhile. Gotta say, the writing was a lot better than what I was expecting from a "18+ warlord harem fantasy" VN.
The world makes a lot of sense for the time period and premise. Nubilia really feels like a proto-nation ready for unification despite the intrigue surrounding it.
Each of the characters have unique personalities and stories. Even people I initially didn't like really started to grow on me when I got into their backstories and problems (EX: Rhea and Priscilla)
One character I was surprised by was the MC. For a self-insert character, he's got a lot going for him. He's smart and strong in the ways you expect from a warlord but his skills are limited to just leadership and violence. His intrigue and political skills are basic and his magical knowledge is non-existent. His sense of honor and relatively lax nature further cement his personality. All in all, he's a surprisingly enjoyable MC and it's nice seeing him interact with the rest of the cast. One of my favorite moments in the story is when Cleo and Amy can read him and tell something is wrong.
I'm looking forward to seeing how Alliances continues the story.
