At the start of the broadcast, the show kicked off with a title call from Todoroki. As this was the first special live event for the project, excitement and anticipation were palpable among the cast during their self-introductions.
The studio featured full-size panels, acrylic stands, and acrylic cards—exclusive paid bonuses available upon purchasing the product—creating an immersive set that truly captured the world of “OVERNIGHTZ.”

The program unveiled exclusive information and rare live readings that could only be heard here. In the first segment, “Peek Inside! The Neighbor’s Experimental Records – Special Cast Gathering!”, details about the mysterious world of the story and character introductions were shared.
As summaries of the plot and character relationships were presented, the cast members focused on the arrows pointing from Ao, Rino, and Kaisya toward “you.” The revelation that these characters love non-human entities—such as dogs, gramophones, or flowers—sparked reactions like “What?!” and “What’s going on here?!”
Additionally, hints about a character who once lived at the Jade Tower and a mysterious black CD sent directly to “you” suggest they hold crucial keys to unraveling the story.
Next, the spotlight shifted to character introductions and cast reflections. Although Ono is often known for portraying intense characters, he described Ao as having a “calmer base tone,” emphasizing balance in his performance.
He also mentioned that listeners should “feel into his inner world” through listening—indicating that many of the reasons behind Ao’s psychological distortion remain unrevealed at this stage.
Yoshino described Rino as someone who “surprises you pleasantly,” despite her seemingly quiet appearance. Words like “You can’t tell from the look” and “Don’t be fooled” hint at Rino’s Rejet-style mysterious, intriguing side.
Having appeared in many previous Rejet titles, Todoroki described Kaisya, who exudes an eerie presence, as “basically well-behaved.” When asked to elaborate further, he simply said, “You’ll have to listen for yourself…”—a comment that made the December release even more anticipated.
Also introduced were supporting characters such as Tō-sama (voiced by Shunsuke速水) and Tafune (voiced by Yū Kobayashi), followed by a deeper exploration of the story world based on three key words. Three black envelopes were placed before the cast members—each containing one keyword.
With keywords such as the “Jade Tower,” the ultimate drug called “Oltanciā,” and the black CD recording twisted love, relevant materials were gradually revealed.
Here, differences in perspectives between Tō-sama and Tafune, along with an overview of the mysterious drug, significantly deepened viewers’ understanding of the story world.
The topic of the “Multiple Endings” was also addressed. The common main route lasts approximately 60 minutes, with three branching routes (each 30 minutes), totaling 90 minutes. Cast members were amazed: “That’s 150 minutes if you listen to everything…!” and “Incredible…”
This segment concluded with a special message from Shunsuke Hayami (voice of Tō-sama) and Yū Kobayashi (voice of Tafune), directed to viewers who tuned in live.
They answered questions like their thoughts after performing the roles, and what kind of new drug they’d develop. Hayami said: “The world feels extremely beautiful and captivating,” while Kobayashi remarked: “Tafune is mysterious but also hardworking, with a slightly playful side”—offering fans rare glimpses behind the scenes.
Next came “Jade Tower Bulletin Board – Live Broadcast Special,” packed with exclusive information. A portion of the main content from “case.I Tōji Ao,” set for release in October, was unveiled—effectively conveying the story’s atmosphere to viewers.
The introduction to the “Complete Series Bonus Drama CD” stood out even more due to its stark contrast with the dark main storyline. Additionally, it was announced that Hayami and Kobayashi would appear in the Animegao “Night Overcome! OVERNIGHTZ Guilty☆Cooking Battle” bonus event—further raising anticipation.
Meanwhile, sample voice clips for Ao and Rino were already available on Rejet’s official YouTube channel. Prompted by fans’ curiosity about Kaisya’s samples, his preview clip was also released at this moment. Ono and Yoshino both reacted: “He’s definitely an abnormal person (laughs),” and “We’re in the same league (laughs).”
The announcement of “Harmful Star-sama,” the theme song for the project, along with its full PV release, left the cast members stunned. The dark, gothic world is deeply reflected in both lyrics and melody—so captivating that viewers couldn’t help but be drawn in.
Finally, the last segment was a live reading drama titled “Jade Tower Secret Experimental Record.I,” featuring an original story available only during this broadcast.
The plot revolves around three characters planning to welcome a new test subject by sharing their knowledge of the Jade Tower as senior participants. The warmth and personalities they display in dialogue make it enjoyable not just as entertainment, but also as pre-release “preview material.”
In a final announcement segment, viewers were informed about the “Brochure Giveaway Campaign” at Animate (valid post) and details on the upcoming “Stella Wares Autumn Rejet Festival” (valid post), further building excitement ahead of the release.
The broadcast ended with heartfelt reflections from the cast. Ono expressed: “When I heard that both Yuuki and Hiroshi were cast, I was so happy,” adding that having them present live made him feel reassured.
Yoshino also shared his thoughts on the unique charm of this special event: “It’s a wonderful time when we can all say lines together.” Meanwhile, Todoroki highlighted the work’s distinctive quality as “a very voluminous production” and urged fans to listen to all three titles in sequence—making the October release even more eagerly anticipated.
The broadcast concluded with energetic goodbyes from all three cast members: “Bye-bye!” The first-ever special live event had successfully come to a close.
