"Oh, so
Nakata Jouji is doing the narration for his fictional daughter's arc" was my first thought when I heard him
Narration was uneeded and not particularly funny but it's always nice to hear Nakata-san's manly voice. I'm not sure if Sae's voice actress improved or if I'm just getting used to her voice, but I enjoyed her performance in this episode. She did a nice job as this utterly shy kohai with large breasts. I'm starting to like the character as well. Her ending song was pretty terrible though.
That was a nice and fun episode, way better than I thought it'd be. Sae's shyness is endearing, however, I think she's a little too shy for my tastes. I hope she'll improve throughout for the arc.
The true star of the episode was Miya for me (`･ω･´). Some great moments with her.
PS: Sae gets +10 point for being the only heroine wearing thighhighs everyday.
