Hmm, this show is starting to get a lot more interesting. I did like the way it toyed with clichés of the genre, with Sena learning to swim in an afternoon, rather than the typical drowning and rescue scenes. He also got to bitch her out for well...being a bitch.

Random tidbits:
- The insults Yozora throws Sena's way are just getting better and better. It's particularly notable that she used English to call her a dutch wife. There's no embellished translation here. Yozora is really being that vulgar with all the others.
- The Sacred Boobsmith hentai game? Heh.
- Does his sister have real heterochromia, and coincidently found an anime character with exactly the same colors, or is she somehow wearing a contact? Either way, it's cute that she's gotten lonely now that he's got a few friends.
- The first time he met Yozora...he punched her in the face. Awesome.

I suppose that the harem aspects are beginning to develop now with Sena and Kodaka's date, even if it was only she who realized that's what it really was by the end of it. Kodaka was just helping a friend. Then we've got Yozora as the childhood friend, a sister with a brother complex, and two or more girls also joining the club in the next episode or two. But it's clear it will be between Yozora and Sena.
