With only 2 episodes left, episode 23 still feels like a building up episode. I suspect that most of the new information we suddenly receive is aimed more towards next season rather than building a grand ending for this season.
So we still have issues in Minami. We have our heroes having doubts about returning home. If anything, this episode shows how Iselus, Lenessia’s little brother, gets closer to Isaac. Then we have a little incident that affects People of The Land. Not much really.
