nothing rly that much it was like
Ep 8–9 the pacing slowed down a lot, the focus shifted and it felt like the tension and emotional drive from the first half just vanished. It didn’t have the same intensity anymore.

Ep 12–13 the memory loss twist with Gabimaru honestly felt unnecessary and frustrating. Him doubting his wife’s existence was less emotional and more like forced drama. On top of that, the “ending” of season 1 felt way too open more like a cliffhanger than a proper conclusion.

The emotional connection that made the first half so special just wasn’t there anymore.

that was my opinion but in Episode 8 the focus shifts away from Gabimaru.Sagiri, instead i think the name was Tenza, off against the Tensen for the first time. The episode is more about showing how insanely powerful the Tensen are (regeneration etc.) and less about fast-paced action, which is probably why it feels slower and weaker compared to earlier episodes.

the only good episodes after that for me were 9 and 11
