No Export for You: The light novel/manga adaptations are not available outside of Japan/Asia.
The Other Darrin: Most of the characters originally from 428: Shibuya Scramble 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 Yoshino Nanjo, 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 Atsushi Ono.
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 Yoshino Nanjo as The Other Darrin 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, Kenji Hamada voicing him in the anime is actually role reprise, as Minorikawa was an Ascended ExtraPromoted to Playable 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 Kinpachi-sensei series.
