I love this show!

First episode had it all:

Main character shows off awesome skillset
Main character gets a kiss by the most popular chick in the show
Girl exposes their relationship in front of everyone
Love rival appears and has a showdown with our main guy
Adorable love interest dies an emotionally imprinting death, mood caries over through the ED

I'm hooked already, and since I haven't watched a sports anime in a LONG while, it'll be a very refreshing change. But that eldest sister really looked like a guy. I was still thinking she was a guy until I saw the female uniform in the preview. Last time this happened was back all the way with Haku, but the other way around.
