The second season of the anime began airing on April 6, 2008. It was broadcast in the same aspect ratio as the original production, which is a 16:9 widescreen format.
At 17:00 p.m. (Tokyo time) on April 15, 2008, a system error preventing malicious submissions occurred at BANDAI's online broadcast channel, which is responsible for the program's online distribution, and the third episode of the program, which was supposed to be aired four days later (April 20), had a 5-minute and 51-second-long dailies (which included a portion of the program's Part 3, the entire Part 4, the ED, and the fourth episode of the program) that had been broadcast. (which included part of Part 3, the entire Part 4, the ED, and the preview of the fourth episode of the show) was mistakenly uploaded to the Internet and revealed in advance. Due to the poor airtime, the ratings were as low as 1.4%. Some netizens began to fear that the series would be canceled.
