!!Anime/Manga/LN:

* MarthDebutedInSmashBros: The original ''VisualNovel/FourTwoEightShibuyaScramble'' the anime is based off of wasn't released in English until 2018, nearly 10 years after its Japanese release.
* NoExportForYou: The light novel/manga adaptations are not available outside of Japan/Asia.
* TheOtherDarrin: Most of the characters originally from ''VisualNovel/FourTwoEightShibuyaScramble'' are not played by the actors from the game’s live action scenes, and are instead voiced by professional voice actors.
** Maria is voiced here by Creator/YoshinoNanjo, whereas she was played by Narumi Konno in the original ''428'', though Konno does reprise the role of Maria’s twin sister Hitomi for a brief voice cameo.
** Takuji Oyama played Kenji Osawa originally, but he is voiced here by Creator/AtsushiOno.
* PlayingAgainstType:
** Creator/MaayaSakamoto is '''not''' known for playing characters like Al Sheya.
** Liang Qi is one of the few villainess roles for Creator/RieTanaka, too. Same with Creator/JessicaBoone.
* RoleReprise:
** Besides Canaan, Alphard, and Siam having the same voice actors they did in Canaan’s bonus route from ''428'', Narumi Konno voices Hitomi Osawa in the final episode, having played both of the Osawa twins in the live action scenes of the game but otherwise replaced by Creator/YoshinoNanjo as TheOtherDarrin to voice the animated Maria. Ikkyū Juku also reprises the role of Teruo Toyama from the game.
** Although Fumio Kitagami was the live actor for Minoru Minorikawa in ''428'', Creator/KenjiHamada voicing him in the anime is actually role reprise, as Minorikawa was an AscendedExtra PromotedToPlayable in ''428'' who originally debuted in animated form in an earlier Chunsoft game from 2004, ''3-Nen B-Gumi Kinpachi-sensei: Densetsu no Kyoudan ni Tate!'', a tie-in game to the ''Series/KinpachiSensei'' series.
