Desperate to know if she can ever overcome her magical difficulties to be like Shiny Chariot, Akko uses the blue moon's power to search for an answer.
Summary
The episode began at sunset, with Akko training to perfect her Mending Magic mastery. Trying to build a statue that looked identical to the one she's standing before, Akko tried to mimic the statue for the 101st time and failed to make them look exactly the same. Akko got demotivated, and Ursula comforted Akko by stating that she would master it in no time, and afterward, they stopped the training lesson.
Late at night, Akko with Lotte and Sucy got ready to sleep. Akko told them how Ursula was trying to guide her, but wasn't helping that much. Akko then started to wonder if she could ever be like Shiny Chariot, which prompted Sucy to tease her because she's being serious. Lotte stated that Ursula was once a student at Luna Nova too, and it was said that she was in the same class with Chariot. Akko, getting motivated again, left the dorm in order to find Ursula, to ask her if she knew Chariot.
In her room, Ursula stared at the Big Dipper constellation from her window as she recalled her days as Shiny Chariot. When Akko knocked on her door, Ursula hurried to put on her glasses and let her in. While she got some tea from her, Akko asked Ursula if she was Chariot's classmate. Clearly shook by the question, Ursula overloaded the teacup and then reluctantly replied that she was indeed classmates with Chariot, which got Akko excited and led her to ask Ursula how she was in her class and finally asked if she knows where she was now. When Ursula didn't respond, denoting that she didn't know, Akko was left devastated. She told Ursula how she wanted to become a witch like Chariot since she saw her magic show when she was little, but she felt increasingly unable to do so. Returning to the top of her room, Ursula told Akko that her own teacher taught her the meaning of "Phaidoari Afairynghor", that one should strive for what they wanted to achieve. In the light of the glimmering moon, Ursula trusted Akko in taking care of Shiny Rod and announced that tonight was the night of the blue moon.
In her office, Headmistress Holbrooke discussed with Samantha Badcock and Lukić about the decay of magic and the decrease in the number of witches in the world. They remembered how the Nine Olde Witches founded Luna Nova when magic was abundant in the world but now they couldn't even use magic without the Sorcerer's Stone. During the discussion, Diana appeared asking for a book about the Nine Olde Witches. The headmistress told her that it was in the secret archives of the academy and gave her a special key to access it. She also told her that it was a blue moon's night, which could lead to the unveiling of certain mysteries.
After seeing Shiny Chariot in a dream, Akko remembered the spirit that appeared on the nights of a blue moon, who could answer any question about the past, present, or future. Akko decided to go to the New Moon Tower to find the spirit. Akko arrived at an old chapel in Luna Nova, and the Shiny Rod opened the entrance to the Blue Moon Abyss where it was said that the spirit appeared.
In the reference archives, the blue moon revealed to Diana the book she was looking for, which entailed how the Nine Olde Witches sealed a magic capable of world reconstruction, known as the Grand Triskellion in the Arcturus Forest and that the seal could only be broken with the staff of the seven stars and the Seven Words of Arcturus. At the same time, Ursula remembered the day Akko arrived at Luna Nova when she unknowingly revived the First Word of the Seven Words of Arcturus when using the Shiny Arc. Then, the blue moon's light illuminated her water pool, showing Ursula that Akko was in the Blue Moon Abyss.
In the Abyss, Akko encountered several visions of spirits that told her to leave. She panicked and fell down a slope, and landed before who appeared to be Shiny Chariot. An excited Akko asked how she could become like her, to whom "Chariot" replied that it was impossible for her to achieve such a dream. Akko then realizes that she was not the real Shiny Chariot and confronted her about it, and "Chariot" was revealed to be the spirit of the blue moon. When Akko asked if she could answer any question, the ghost told her that no one can answer what she could not. Akko asked if she could ever become a witch like Shiny Chariot. The spirit showed her a vision of her turned into Shiny Chariot and told her that she could deliver that future to her, but only if Akko renounced all her past memories. After seeing memories of her experiences, Akko refused to do so, claiming that her past belonged to her even though it was full of mistakes. The ghost asked Akko if she was willing to do it, even if it means not fulfilling her dream, and immediately commanded her to leave when she refused, stating that she would never become like Chariot. Akko replied that she strived to do it, remembering the meaning of "Phaidoari Afairynghor" and reviving the Second Lost Word, as the Shiny Rod glowed and transformed into a giant viking axe which Akko used to attack the spirit.
As the spirit's disguise was destroyed and her real feminine form was revealed, Akko saw a series of visions about future events, after which she fell unconscious due to exhaustion. When Ursula arrived at the Abyss and found her, the spirit revealed herself to be Professor Woodward, one of the Nine Olde Witches who founded Luna Nova Magical Academy and the mentor of Ursula, whom she knew as Chariot. Ursula and Woodward talked about the trial that Akko had just overcome, which led her to revive the Second Word of Arcturus. Woodward stated that while Akko was stubborn, she was quite determined. Before disappearing, Woodward instructed Ursula to guide Akko, so she could open the seal of the Grand Triskellion. As they left the New Moon Tower, Ursula toom an unconscious Akko back to the main campus, promising to tell her the truth about her identity someday.
When the light of the blue moon hits the Shiny Rod, the ray it emits that opens the Blue Moon Abyss's entrance originates from the second star, representing the second Word of Arcturus, Phaidoari Afairynghor.
Ursula's startled reaction when Akko says she watched a Shiny Chariot show is explained in "Chariot and Croix".
Young Akko accompanied with her black pet cat in a flashback. The scene also reveals that she has a number of Shiny Chariot-related paraphernalia, a fake crystal ball, and a small broom
As shown in the flashback from her elementary years, Akko has Shiny Chariot-related merchandise in addition of Chariot cards; a poster and calendar, and magic magazine from which she learns about Blue Moon Abyss and other things from magic world as much as Chariot cards. She also owns a fake crystal ball and a broom with red ribbon reminiscent to Luna Nova-issued magic broom she would receive years later, and a black pet cat.[2]
