When Gintoki apprehends a movie pirate at a premiere, he checks the camera's footage and finds himself transported to a bleak, post-apocalyptic version of Edo, where a mysterious epidemic called the "White Plague" has ravished the world's population. It turns out that the movie pirate wasn't a pirate after all—it was an android time machine, and Gintoki has been hurtled five years into the future! Shinpachi and Kagura, his Yorozuya cohorts, have had a falling out and are now battle-hardened solo vigilantes and he himself has been missing for years, disappearing without a trace after scribbling a strange message in his journal.

Setting out in the disguise given to him by the android time machine, Gintoki haphazardly reunites the Yorozuya team to investigate the White Plague, and soon discovers that the key to saving the future lies in the darkness of his own past. Determined to confront a powerful foe, he makes an important discovery—with a ragtag band of friends and allies at his side, he doesn't have to fight alone.

A Japanese actor, voice actor, singer and narrator from Shiogama, Miyagi Prefecture. He graduated from Tohoku Gakuin University's economics school and is currently affiliated with Across Entertainment.

He was the manager of the Tagajou Senior High School basketball team before he made a name for himself. His voice acting debut was the OVA [Megazone 23](https://anilist.co/anime/1935/) as the motorcycle-riding [Shinji Nakagawa](https://anilist.co/character/56633/), while his television debut was the anime [Bosco Adventure](https://anilist.co/anime/3460/) as the cowardly Otter. His break-out role, however, was in the anime [Ranma ½](https://anilist.co/anime/210/), in which he played the dual role of [Hibiki Ryoga](https://anilist.co/character/2369/) and the [Jusenkyo Guide](https://anilist.co/character/58321/). In 1991, Yamadera joined forces with [Toshihiko Seki](https://anilist.co/staff/95129/) and [Noriko Hidaka](https://anilist.co/staff/95181/) to form the acting unit Banana Fritters, which disbanded in 1995. In October 1997, Yamadera became a host on the TV Tokyo children's variety show Oha Suta. In March 2016, after almost two decades, he announced his retirement from it.

Yamadera's also known for his versatile range, as shown in the video game Danganronpa V3: Killing Harmony where he voiced all five Monokuma Kubs, including Monophanie (female). According to the Danganronpa V3 official blog, Yamadera is the first person who came to mind as "the same person voicing multiple characters at the same time". No one has as much "multiple characters" experience as him. He was able to take the individual quirks of each of the Monokuma Kubs and make all of them unique.

Other notable examples of multiple voice acting include the Kingdom Hearts series where he voiced Donald Duck, Genie (Aladdin), Sebastian (The Little Mermaid), Beast (Beauty and the Beast), Mushu (Mulan), Jaq (Cinderella) and Stitch (Lilo and Stitch), and the [Japan Animator Expo](https://anilist.co/anime/20947/) series of 35 short films where Yamadera and [Megumi Hayashibara](https://anilist.co/staff/95014/) voiced all characters.

Yamadera was married to fellow voice actresses [Mika Kanai](https://anilist.co/staff/95029/) from 1993 to 2006, and to [Rie Tanaka](https://anilist.co/staff/95060/) from 2012 to 2018. On June 14, 2021, his marriage to singer and idol Robin Shoko Okada was announced.
