Chapters 75, 76, and 77 are unusual in that they're produced by Rie Takahashi, Takagi's Japanese voice actress, and Yūki Kaji, Nishikata's Japanese voice actor, respectively.
In the Latin American Spanish dub, Eduardo Garza (Nishikata) is the ADR director.
No Dub for You: For Season 1, there are no dubs other than Japanese and English. This is averted for Season 2 due to the side effect of Netflix acquiring the rights for it and thus releasing various other dubs.
The Other Darrin: Due to Netflix acquiring the rights for Season 2, none of the Funimation English dub cast returned to reprise their roles. The dub was instead recorded at VSI's Los Angeles studio.
Relationship Voice Actor: The Latin American Spanish dub reunites many members from the voice cast of My Little Pony: Friendship Is Magic: Takagi (Analiz Sánchez) is Rainbow Dash, Nishikata is Jet Set, Yukari (Susana Moreno) is Apple Bloom, Nakai (Miguel Angel Ruiz) is Snips, Mano (Andrea Arruti) is Diamond Tiara and Kimura (Tommy Rojas) is Bright Mac.
Teasing Master Takagi-san and its Spin Offs are set in the Real Life island of Shōdoshima, the hometown of the manga's author Sōichirō Yamamoto. Some of his more fantastical works also take place on the island (Fudatsuki no Kyouko-chan) or in that world at large (Kunoichi Tsubaki no Mune no Uchi), thus making most of Yamamoto's works part of a Shared Universenote Which seems to be the case when Nishikata and Takagi are The Cameo in the final volume of Kyouko-chan.
