“The Dying King and the Four Knights” - Main Story #8
While Shiori was being attacked by a Korosu, Akira shouts “Marquis!” and jumps in to save her along with Michiru. After it’s defeated, Akira says, “That’s right… I remember now. You are… Yumeoji Shiori.” Later, Akira asks Michiru about Shiori’s work method. And Michiru says that she heard from the other middle school students that Shiori hasn’t been doing well in her classes recently. She says the teachers have been worried too, and that they’ve been talking about how it might have been too soon for a middle school student to become an Edel after all.

Akira keeps supporting Shiori and being protective of her as she insists that’s not the case. That she chose Shiori to be Frau Jade because it could be no one but her. Michiru says she knows, but that the expectation might be "too heavy of a burden."

The scene changes to the rehearsal room where Shiori is playing the piano. When she stops, Akira begins clapping and tells her it was a wonderful performance. Surprised, Shiori stands up but Akira says there’s no need to and tells her to continue. Shiori says she was just playing a bit as a change of pace. Akira says she’d like to hear more. Shiori hesitantly agrees, and begins playing again.

Afterwards, Akira tells her it was wonderful and Shiori says she’s a bit embarrassed. Akira tells her that the music she plays has a kind and gentle tone. Shiori begins saying that her sister, Fumi, is much better at the piano, but stops and apologizes. Akira says that she was praising Shiori’s piano and that Fumi has nothing to do with it. Shiori begins tearing up.
