Kannagi: Crazy Shrine Maidens (TV)

in ep 10, when everyone goes to karaoke, jin walks into the wrong room and runs into the lucky star girls

in ep 10, the opening theme of this anime is playing in the background.

The beginning of episode 10 is a parody of the endings of Lucky Star. The camera is focused on the door of a karaoke box and slowly zooms out, as the characters are inside chatting away. Later Jin accidentally enters a box with a group of girls bearing a striking resemblance to the Lucky Star cast.

During the broadcast, the flashing of the neon sign "nagi" in the opening sequence was toned down starting episode 3 to remove the possible "Pokemon Flash" effect.

In the middle of episode 5, about 7 minutes in, the director Yutaka Yamamoto makes a cameo as himself (realistically drawn), saying "thanks to Nagi-sama, I was promoted to anime director..."

In episode 2 around 16.00, Nagi said "If it is gathered 7 of them", this is a reference from Dragon Ball.

In episode 6 around 12.30, you can see Colonel Sanders of Kentucky Fried Chicken behind Takako.

In episode 6 around 02:23-02:26, you can see Haruhi (Melancholy of Haruhi Suzumiya) with blue hairband passed by

In episode 8 around 20.30 while Daitetsu were screaming, you can see Puniata, featured in the manga series's omake & also featured statue of Eri Takenashi, the author of Kannagi, ran out of the toilet.

In episode 10, the room that Jin walks into was 301 which is the same room number that the girls in lucky star were in when they were singing karaoke in the credits of Lucky Star.
