By far, this was the episode that I most anticipated to watch adapted from the manga into the anime.
Saeko-sama showed and confessed her very, true colors to Komuro in shame but with acceptance at the same time.
What I felt watching Saeko thrashing the zombies at the park was that the anime waterdown her sadistic behavior, though that scene implicitly hinted at Saeko's unbound sadistic pleasures.
Spoiler:
What I feared the most was the confession inside the shrine, because Saeko's displays shamelessly a crazed, euphoric, and psychopathic eyes to Komuro about her secret fetish in the manga.
For the anime, her insane eyes weren't on par with those on the manga, but the spirit of haunting insanity was preserved due to the addition of thow3 flashback sequences which depicted Saeko-sama beating remorselessly and standing triumphantly, with those murky, cold, but very inviting eyes to sadism, on the guy who assaulted her.
The choice of music was superb to expose to the audience her darkness, and made clear that she can't help it.
This is more evident with that beautiful display of swordmanship at the shrine during the morning duel, after Komuro groped her bust and enraged woke up sense within Saeko-sama that she accepts her for who she is.
Please, does anyone agree with me that the best one-liner delivered in this episode by Saeko-sama was: "I'm Getting Wet"
Oh, lol as hard as I never did for this show, honestly.
