In the bonus episode, the group of players who don't make the cut to play in the competition form a B-Squad named Monaka, after the first character of their three second-year members' names.
When they announce this name to the rest of the club, Asuka misunderstands and thinks the name has something to do with youth:
Asuka: "Monaka". We're in the thick of our youth! Or something.
Girl: No, we just took the start of the second-years' names.
Where did Asuka think they had gotten the name "Monaka" from?
