‘Miraculous Ladybug’ Season 6 Episode 23 Release Date, Time, and Where to Watch ‘Sadnansi’
‘Miraculous Ladybug’ season 6 has continued to roll out across multiple countries throughout 2025 and into 2026, and episode 23 lands at a genuinely pivotal moment in the season. Titled ‘Sadnansi,’ the episode centers on Marinette as she wrestles with whether to finally tell Adrien the truth about his father Gabriel’s villainous past, a secret she has been carrying since Chrysalis took the Butterfly Miraculous after the death of Monarch and began creating new akumatized villains for the heroes to fight.
The episode carries real weight for the ongoing Adrienette relationship while still delivering a full villain confrontation, and viewers trying to track down exactly when and where to watch it have understandably had questions given how the show’s rollout differs from one platform to another.
Miraculous Ladybug Season 6 Episode 23 Release Date and Time
Season 6 of ‘Miraculous Ladybug’ began airing in the United States on Disney Channel starting January 25, 2025, more than a year after season 5 had ended. In France, the same season officially premiered later, with the sixth season debuting on TFOU on 23 March 2025 and running for a total of 26 episodes.
On Disney’s own streaming hub, DisneyNOW, ‘Sadnansi’ is actually catalogued as the nineteenth episode in that platform’s listed order, which sits differently than its placement as the twenty third episode written and produced for the season according to the show’s own fan wiki. This kind of numbering gap is not unusual for the franchise, since the series airs in roughly 150 countries, each following its own episode order.
Disney+ eventually became the season’s main US streaming home, and the first eight episodes of season 6 all dropped there together on July 2, 2025, at 3 a.m. The broader US broadcast run for the season, tracked by the franchise’s own fan wiki, extended out to August 8, 2026 on Disney Channel, which gives some sense of how long this rollout has stretched across the calendar.
Where to Watch ‘Sadnansi’
For anyone trying to catch up now, season 6 of ‘Miraculous Ladybug’ is available across a small handful of services. A streaming availability check dated September 24, 2026 found the season listed on Netflix, Disney Plus, YouTube TV, DisneyNOW, Netflix’s ad supported tier, and fuboTV.
There is currently no fully free streaming option confirmed for the season, so viewers without one of those subscriptions or a live television package will need one of the paid or ad supported options to watch. That makes DisneyNOW or a Disney+ subscription the most straightforward paths for most households.
On DisneyNOW specifically, ‘Sadnansi’ sits among a run of season 6 episodes that includes ‘Lady Chaos,’ ‘Heartfixer,’ and ‘Riginarazione,’ which helps place it within the back half of the season’s overall episode count.
Episode Preview and Plot Details for ‘Sadnansi’
The episode opens on a striking image, with Ladybug standing over the torn up remains of a drawing of Gabriel that Marinette had been working on, immediately setting a heavier emotional tone than many of the season’s earlier entries. From there, the story follows Marinette as she struggles with the emotional burden of keeping Gabriel Agreste’s villainous history secret from Adrien, with her stress eventually building into a genuine internal crisis.
By the episode’s end, Marinette retrieves a letter that Gabriel had written to Adrien from inside her yo-yo, and after talking things through with her kwami Tikki, she makes the decision to finally tell Adrien the truth and to be there for him once he learns it. That resolution gives the episode a clear emotional arc that pays off a tension the show has been building since Gabriel’s downfall.
Alongside that central storyline, there is a lighter subplot in which Marinette becomes convinced that her sister Nora and Nora’s coworker Twig have feelings for each other but are too nervous to admit it, which pushes Marinette into playing matchmaker between the two of them.
On the action side, the villain Sadnansi attempts to pull down the Eiffel Tower, only for Carapace to catch it with his Shell-ter power so Ladybug can set it upright again. Cat Noir and Rena Rouge both join the fight soon after, with Ladybug using a Lucky Charm umbrella to block an attack before the group works together to bring Sadnansi down.
How Episode 23 Fits Into Season 6’s Larger Story
Season 6 as a whole picks up in the aftermath of Monarch’s death, with a new villain called Chrysalis seizing the Butterfly Miraculous and using it to keep generating fresh akumatized threats for the Miraculers to handle. That ongoing conflict runs alongside a second, more personal thread involving a secret society that Gabriel Agreste had once belonged to, which is part of what makes Marinette’s dilemma in ‘Sadnansi’ feel so consequential to the season’s bigger picture.
Season 6 also represents something of a technical turning point for the franchise, since it is the first season animated using Unreal Engine, a change from the Autodesk Maya software that had been used across the first five seasons. That shift has been noticeable in small ways throughout the season, including added effects during Ladybug’s signature power sequences.
With Marinette finally choosing to tell Adrien the truth by the end of ‘Sadnansi,’ anyone who has followed the Adrienette relationship this closely through season 6 likely has thoughts on how that conversation should actually play out once it happens on screen, and this feels like exactly the episode worth discussing in the comments below.
