Errors

 * When Sougo returned the Decade Watch to Tsukasa, the former somehow had it in his possession, even though a couple scenes ago, it was previously stored on the Ridewatch Daizer in 9 5 DO back in 2019. This has happened on several occasions in past episodes where both Sougo and Geiz would suddenly have other Ridewatches on hand despite them being on the Daizer in the first place.
