Gogo 4-ji. Tomei, Tokidoki Seiyu: Manga Launches on KimiComi
The comic adaptation is based on the two-volume light novel by Misaki Saginomiya and Haru Ichikawa.

The light novel "Gogo 4-ji. Tomei, Tokidoki Seiyu" is receiving a manga adaptation, which has launched on KimiComi. Kill Time Communication confirmed this in a statement dated September 19, 2026; Nijimen picked up the launch on September 22.
Sisseki is responsible for the manga version. The source material comes from Misaki Saginomiya, and the character designs are by Haru Ichikawa. According to Nijimen, the original light novel so far spans two volumes.
The story centers on high school student Ryona Yamada. A classmate publishes a video featuring her voice without her consent. Her voice sounds so similar to that of well-known voice actress Shion that the video quickly attracts attention. Shortly afterward, the voice actress's manager contacts her, and eventually Shion herself gets in touch.
The story's starting point is an unusual role swap: Ryona is to replace the famous voice actress. For the schoolgirl, who has so far experienced herself as inconspicuous and little noticed, this becomes her entry into the professional voice acting world and thus into anime production.
Kill Time Communication's official announcement refers directly to the KimiComi edition and classifies the series as a youth story about a "substitute voice actress." The sources read do not name a date for a printed manga edition.
Thematically, the series connects light novel, manga and the voice acting world. Other current adaptation news on aninew.de includes Aoharu Once More: Light Anime Adaptation Announced and Black Bullet: Light Novel Returns After Twelve Years.
