To go alongside the new animated series by J.C. Staff, an OAD covering later portions of the manga was released prior to the main anime with UQ Holder's volume 14 limited edition manga. After the anime's debut, two additional episodes were announced and are planned to be released with the limited edition versions of volumes 16 & 17 of the manga.
The first OAD, named "Amor Primus 〜First Love〜" was released September 8th, 2017. It roughly covers chapters 77-81, 83-85, and 97. The episode is about Yukihime recalling her first love, when Touta meets her 16-year-old self and solely focusing on their relationship, ultimately writing out the training portion for the rest of the UQ members.
The second OAD, "Eternal First Kiss in a Moment" was released with UQ Holder! Vol 16 Manga Limited Edition on March 9, 2018. It covers chapters 104-106, focusing on Kirie and Touta as they find themselves stuck in time. The episode follows the anime's canon and takes place after Negi's first fight with the UQ Holders, unlike the manga's timeline. It also writes out Santa's brief cameo, as he did not appear in the anime series.
"Karin Senpai's Secret That Can't Be Spoken", the third and final OAD announced, was released with UQ Holder! Vol 17 Manga Limited Edition on June 8, 2018. This episode focuses on Touta's relationship with Karin, covering the entirety of chapters 107-109 and the very beginning of chapter 110.
Sentai Filmworks announced the OAD's would be localized and included with their Blu-ray release of the TV series. It will have an official English sub and dub.
