Brynhildr does not have an auspicious cold open, consisting of a pointless comparison between the girls boob sizes. After the OP Kazumi starts sexily teasing Ryouta again. Then something unexpected happens: Ryouta actually calls her out on it. I for one appreciated the show acknowledging the fact Kazumi was trying way too hard.
Kazumi’s response is telling: she tries her hardest at everything; including, er…romance, apparently. Ryouta, meanwhile, has something less romantic in store for his new club-mates: a stargazing party. Sure, the girls are being hunted, and will eventually run out of life-giving pills again, but that’s all the more reason to live their lives to the fullest, while they still have them.
The trip is a success, with everyone getting way more into the astronomy than they thought (even Kazumi), right until Kana starts having visions: first of newbie Kotori standing over a dead Neko, then of a dead Ryouta. Meanwhile, another B-rank witch Shino is on the run from an AA+ named Kikako (looking like a character out of Kill la Kill), and Neko insists on helping, out of loyalty to B-rankers.
Kotori is the one everyone suspects of being the murderer, but Kana doesn’t actually see her killing anyone, suggesting Kikako is the true culprit. Shino doesn’t last long against Kikako’s huge mouth-cannon, and since Neko gave away their position, either she or Ryouta will be the next targets, if they don’t find a way to change Kana’s predictions.
