Random Sayaka tip: K5 06/15

I was reading Memolist site today to see what had happened in today's (06/15) K5.

The site has not the whole show transcription as usual yet, just the main parts.

So well, Sayaka said today that at elementary school times the boy she liked called her "Sachiel" (one of the 'Angels' in Evangelion). She didn't know who Sachiel was so she went to the video store and discovered it was a.... Superb robot. ^^;

I wonder why the kid called her like that... Was Sayaka some kind of destruction robot or something? Who knows.
