When I said star-studded, I meant it. Look at the seiyuus: among them are Azumi Asakura (IdolMaster’s Hagiwara Yukiho), Shiori Mikami (Shingeki no Kyojin’s Krista Lenz), Maaya Uchida (High School DxD’s Irina Shidou, IdolMaster’s Kanzaki Ranko), Aya Uchida (Love Live’s Minami Kotori) and Rumi Okubo (Fate/Apocrypha’s Astolfo).
