New footage also previewed for new season beginning on April 8

TV Tokyo began airing a television commercial for the upcoming Gintama series this past weekend. The commercial shows clips from the upcoming show, and previews the show's opening theme "Day x Day" by Blue Encount.

Kagura: Gintama anime!

Shinpachi: It's a bit embarrassing...

Gintoki: But we're back!

Kagura: Even though it concluded!

Shinpachi: We've come back!

Gintoki: Quite shamelessly! But putting the past behind us...

Everyone: We're in your hands again!

Gintoki: Gintama , starting on Wednesday, April 8 at 6 p.m.!

Shueisha's Weekly Shonen Jump magazine revealed the show's April 8 premiere date last February, as well as revealing that Blue Encount will perform the show's opening theme "Day x Day," and Negoto will perform the show's ending theme "Destiny."

Hideaki Sorachi's original Gintama action comedy manga inspired a television anime that premiered in 2006 and continued (with several extended hiatuses) until 2013. It also inspired two movies, including the "final" Gekijōban Gintama Kanketsu-hen: Yorozuya yo Eien Nare film that opened in 2013.

Last year's Jump Special Anime Festa event tour debuted a one-episode Gintama special in November. That special is shipping on a DVD with the 58th manga volume on April 3, 2015.
