Nobody talks about this one. That's because it exists in the margins of a franchise most people abandoned after the show, but if you found something real in D4DJ's mess of characters and rhythm-game tie-ins, this special is exactly what you came back for: three minutes of set preparation anxiety, a chapel scene that nails the specific loneliness of wanting something badly, and an OST that treats a one-off festival like it matters. The show moves slow and asks nothing from you except to sit with girls who care about their music. You get out what you bring to it.
The legendary D4 FES festival is back, and Merm4id finally has their shot at the stage they've always dreamed of. But as the girls prepare for their big moment, something feels off about Rika. Her bandmates catch her acting strange during a photo shoot, and nobody can quite figure out what's going on in her head. Meanwhile, Tsubaki from RONDO finds herself alone with her thoughts, imagining what doors might open for their group next. When Rika suddenly shows up at the clubhouse after a live performance with wild energy and an unexpected proposition, everything shifts. She's the kind of person who charges forward with pure optimism and luck, ready to shake things up. This special episode brings two groups together at a pivotal moment, capturing that electric feeling when a festival weekend could change everything. It's a slice-of-life snapshot focused on friendship, ambition, and the kind of spontaneous decisions that happen when you're surrounded by people who get you.
