Gate: Jieitai Kanochi nite, Kaku Tatakaeri - Enryuu-hen Episode 3 Impression
On this episode, the dark elf causes a problem for Itami and his gang. Meanwhile, the Empire's bunny slave plans an evil scheme.
So it seems the coming big dragon battle will show up in the middle of the season instead as a finale because of the story progression rate I read in the manga. However I might be wrong. Anyway, the build up for the dragon plot was decent. Also the dark elf explained her request which is nice. Now what's going to be the next plot for our main group? Overall, a decent build up for the dragon battle.
Conclusion: A decent build up for the dragon battle.
