Marriage Toxin anime releases creditless opening and ending videos

Bones has published the creditless opening and ending videos for the Marriage Toxin TV anime, along with a special promotional segment, handing the spring 2026 series a fresh burst of attention a few weeks into its broadcast. The clean versions land on official channels and have been picked up widely by the anime community as standalone animation showcases.

What Bones released

The creditless cuts strip staff overlays from the opening and ending sequences, letting viewers see the full animation Bones produced for the title cards. A separate special video was uploaded alongside them, bundling behind-the-scenes promotional material with footage from the show's opening arc. Creditless uploads are a standard mid-cour marketing beat, but they also function as a litmus test for how a series is being received an OP that lands tends to trend hard once the clean version drops.

Marriage Toxin is directed at Bones, a studio with a deep catalogue in character-driven action, and the series adapts the Shueisha manga serialised on Shonen Jump Plus. The story follows Gero Ichijo, a young hitman from an assassin family who is ordered to retire and find a wife within a year or face erasure. He partners with matchmaker Mei Tsumugi, and the series blends action set pieces with a romantic-comedy core that the OP and ED sequences both lean into.

A mid-season boost for the spring 2026 slate

Marriage Toxin premiered earlier in the spring 2026 season and has been running weekly, with episodes building out the Gero-Mei dynamic while introducing the assassin-world antagonists from the manga's early arcs. The creditless release arrives at the point in a cour where studios typically push secondary marketing isolating the OP/ED as shareable assets, driving social clips, and pulling in viewers who skipped the premiere week.

The opening and ending themes, performed by the previously announced artists attached to the project, have been among the more-discussed musical debuts of the season, and the clean videos give the visual side of those sequences room to travel on their own. For animation-focused viewers, the creditless cuts are often the definitive version of an OP, and Bones has a track record of rewarding that audience.

India and streaming availability

Marriage Toxin streams on Crunchyroll, including Crunchyroll India, where the series is available with subtitles as part of the spring 2026 simulcast slate. New episodes go up weekly in line with the Japanese broadcast schedule, and the creditless OP and ED, along with the special, are being circulated on the show's official video channels rather than being gated behind the streaming platform. Indian viewers following the simulcast can catch the clean versions without a subscription, while the full episodes remain on Crunchyroll's catalogue.

What to watch next

With the creditless videos out and the season past its opening arc, the next marketing beats will likely be keyed to the manga's bigger set pieces adapted later in the cour. Bones has not announced any extension beyond the currently scheduled episode count, and any confirmation of further episodes would typically come closer to the finale.
