Released in Disc Station Vol 13, Arle's Travel Log is a text-adventure game where Arle is confronted by Satan on her way to magic school, who wants Carbuncle back. The three battling together accidentally cause them to be sent back in time, with Arle and Carbuncle looking for a way to return to the present. The gameplay consists of exploration similar to the Madou Monogatari series, along with elements of an adventure game. Arle can talk to characters she meets or can click on various items to progress the plot. Battles can also occur in-game, and are fought by using a click-and-point system. The game casts various Madou Monogatari and Disc Station characters as Japanese historical figures.
