It drops you back into that summer for twenty minutes and then refuses to explain itself, which is exactly the deal Denpa Onna always offered. Makoto walks to the festival with Ryuuko, ends up at the shrine where Erio is waiting, and gets ambushed by Yashiro announcing she's about to show off a fraction of her psychic power and ordering him three steps back before she lifts her left arm. That Yashiro sequence is the one reviewers keep circling, and it earns it, because the show hands the camera to her head instead of narrating what she means. SHAFT's production budget is visibly still in the tank here: festival lanterns, hard color blocks, the same tilted, over-composed framing the TV run ran on. Nobody's pretending this advances a plot. It's an epilogue, a lap around the block with people you already miss, and if you finished the series wanting five more minutes of them standing around saying strange things at each other, this is the five minutes.

Makoto spends a summer festival night with Ryuuko, then keeps a promise to meet Erio at an old shrine so the two can watch the stars. As the Perseid meteor shower lights up the sky, Yashiro shows up and announces that she is leaving, but first she wants to give a small demonstration of her esper powers. She tells Makoto to take three steps back and lifts her left arm. This unaired thirteenth episode was released with the seventh Blu-ray and DVD volume, and it mixes comedy, mystery, romance and science fiction.
