Seeing Hotaru act that way is kind weird, i mean, we all know she can be like that behind closed doors with her parents but man seeing it twice in a row with Konome watching felt awkward.
Poor Nii-san though, dude just wanders around in the background as per, drops the sack of sugar and no one notices him, then to not only see him as a ghost but for the two to confirm later neither saw him that day. Natsumi, it's your job to notice Nii-san, your the only character who even talks to him!
I always forget Hotaru is only 11/12 years old though, i mean.... they aren't wrong she is mature for her age, even height she dominates or pulls a close second to the others.
Still feels good to have a more Hotaru based episode, one thing worrying me about this season is the effort focus on the minor characters, 2 episodes of Konome and now next is on Hikage, nothing against the minors but i would rather focus on the lead characters (Hotaru, Renge, Komari and Natsumi).
I was pretty thrilled to see Hotaru's still sporting her unique stalker hobby of loving Komari a little too much. I was hoping for a second take at bringing the girls (or just Komari) over and her nightmare of hiding them again, sadly it didn't happen.
