After worrying long and hard over what to do about Shikijou's invitation to go hang out together, Kanade decides to try going on the date with him. When Himuro hears about it she leans forward excitedly to congratulate Kanade on finding someone she might fall in love with. Himuro is also eager to observe and analyze Kanade's date from afar in order to put it to good use in her own research. As she's thinking about this, Yukimura arrives and proclaims that he has devised a new standard unit for the measurement of favorable feeling, the Kanade love power. Then, Kanade's date becomes a double date!
