During the ending theme, Makate Ogata was in Shana's role.
This is the first time Alastor has called her "Shana", in the series.
In this episode, we learn that with the Hougu, Reiji Maigo, Yuuji is able to refuel his flames every midnight.
The scene at the beginning (or near the beginning) is similar to the one in episode two, where Yuuji tried to get Ike and Hirai together after school. This time, though, Ike is trying to get Yoshida and Yuuji together after school.
