Gnosia Radio

The order of episode hosts.

Gnosia Radio, stylized as GNOSIA RADIO, is a web radio show featuring the voice actors of the Gnosia anime that airs episodes irregularly alongside the anime's broadcast. It was announced at Aniplex Online Fest 2025. Each episode is roughly 30 minutes long and features a different voice actor as the host, the order of which was determined in Episode 00 by drawing lots. The official hashtag is "#グノラジ".

The show is meant to evoke the feeling of Yuri being constantly stuck in Loop 1 by trapping the cast and listener in repeated, randomized variants of "Episode 1". Every new episode will involve the featured voice actor hosting a program centered around something related to the character that they play. Episodes were not recorded in order; during Aniplex Online Fest 2025 it was mentioned that episode 14 had completed recording, but episodes 10 and 11 had not. Similarly, in episode 01 it's established that episode 13 had already been recorded.

The concept of Gnosia Radio was proposed by Aniplex PR representative Ayaka Yoshigai, who brought up the idea to radio host Hikaru Ishii and anime producer Yoshitaka Kimura in spring of 2025. The decision to make and air Episode 00 was impulsive, and everyone involved was anxious about whether or not the project would actually be possible given the large cast involved. However, STUDIO MAUSU - the sound production company for the anime - was able to secure time for the show between recording sessions for the anime.

Episode 00

【GNOSIA RADIO】-00｜TVアニメ『グノーシア』2025.10.11 ONAIR

Airdate: September 13th, 2025

This episode is hosted by producer Hikaru Ishii, who explains the basic premise of the show: each episode will be approximately 30 minutes long and will involve each of the voice actors becoming the host of their own radio program. He notes the unusual nature of a program like this for an anime and the difficulty of organizing it all, but that Yoshitaka Kimura - the producer of the anime - insisted upon it.

Ishii then explains that they need to decide the order of hosts and says that they'll do so by drawing lots to tie into the anime being an adaptation of a game. The voice actors ask if it'll be an issue if someone ends up in a role before their character has even appeared in the anime and if the radio show episodes will be correlated with the anime episodes at all, to which Ishii quickly responds no: the radio show will be focused more on the voice actors and not the contents of the anime. He notes that even though only 14 voice actors are there, there are still 15 slots: Kukrushka will still receive a themed episode, which Kimura will be taking the lead on.

The lottery drawing.

The voice actors begin drawing their lots:

• Chika Anzai (Yuri) draws first and gets episode 11, expressing uncertainty about what to make her episode about without spoiling anything but hoping to eat something delicious (which has nothing to do with Yuri, she just wants to).
• Ikumi Hasegawa (Setsu) draws next, getting episode 10, joking that she should make her episode about weight training since Setsu is a soldier.
• Akari Kito (SQ) draws episode 8 and Ishii reiterates that the voice actors don't need to make their episodes about anything related to the anime. Noting this, Kito decides that since she plays SQ, she'll just talk about whatever comes to mind at the time and maybe invite a guest from production.
• Hiroki Nanami (Raqio) draws episode 9 and everyone marvels at how close the numbers have been so far. Nanami suggests hosting a show that features all sorts of different people, with the others suggesting it should stir people up.
• Asami Seto (Gina) draws episode 6 and remarks on Gina's kindness and love of food, suggesting lunch should be bought for the group.
• Saori Hayami (Stella) draws the first episode, to everyone's excitement. She suggests a project where she grows plants, or maybe having a conversation with an AI.
• Tomokazu Seki (Shigemichi) draws episode 2 and says that since his character looks like an alien, he'd like to have an episode discussing urban legends from the industry.
• Aoi Yuuki (Yuriko) draws episode 3 and says that since Yuriko is a sadist, she'll be doing an S-ASMR episode.
• Ayane Sakura (Comet) draws episode 4 and jokes about doing another 100 Days Radio - a previous radio show Sakura hosted where she spent 100 days preparing to play the titular role in Ameku M.D.: Doctor Detective- while making sure she never lies, probably stirring up controversy.
• Yuichi Nakamura (Chipie) draws the last episode: 15. He remarks that the budget and well of unique ideas will probably have run out by then, and suggests the production crew prepare a lot of cats. One of the voice actors suggests going to a cat cafe despite him being allergic to cats.
• Kenjiro Tsuda (Jonas) draws episode 13 and announces that since the anime is based on a game and games are synonymous with Las Vegas, they'll be publicly recording it there, joking that if they win then they'll have the budget for it.
• Kana Hanazawa (Otome) draws episode 14, suggests going to an aquarium, then considers the budget and jokes about getting a wagon and doing the show while moving around in a loop.
• Takeo Otsuka (Remnan) draws episode 12, asks if this is all audio-only, suggesting a video where Remnan gets excited about something in the middle of it for Otsuka to do a radio show about.
• Takuya Eguchi (Sha-Ming) draws episode 5, expresses wonder about what's going on in Sha-Ming's head, then suggests that he should do the show while drinking alcohol. He then jokes that to anyone listening from TBS, he's actually just planning to do a show that follows his daily life.

Once the order has been decided, the show comes to a close. Everyone signs off in reverse order with increasing volume until Anzai is screaming hers, to Ishii's confusion.
