Novelbright's Yudai Takenaka said, ``This is a song that allows us to find a new level of Novelbright while remaining close to the original work.'' Polkadot Stingray commented, ``I've been nervous ever since I saw the news about the anime adaptation.I'm so happy.'' ``So we had no choice but to make a divine comedy, so we created a great song that is powerful! Rock! Disturbing! Dramatic! Above all, it's catchy and cool.''
It has also been revealed that Shinpuku Sakura will play the role of Tsukiko Shimoshima as an additional cast member. Regarding the role of Tsukiko, who is in the same class as Koyuki and belongs to the art club, Shinpuku enthusiastically said, ``I was moved by Tsukiko-chan's unfathomable charm, and I went into the dubbing with the intention of showing a lot of expressions.''
