Comments from the Creators
■Spinoff Author hiroja
Thanks to everyone’s support, if Episode of Mafia is being adapted into an anime. I am already grateful just to be able to draw my favorite characters, but being able to see them move and speak on screen truly makes this a dream come true as a creator. This is another possible world derived from Welcome to Demon School! Iruma-kun. Please enjoy the differences, as well as the slightly dark yet gentle stories of these characters.
■Original Creator Osamu Nishi
Congratulations and thank you for the anime adaptation of if Episode of Mafia. My deepest gratitude goes to hiroja for creating such a high quality spinoff story, and to the anime staff who are giving it new life. Look forward to seeing Iruma and the others show off a different, more sensual charm than in the main series. Let us all wait in front of the television together.
■Chief Producer Takuji Yoshino
Both Welcome to Demon School! Iruma-kun and if Episode of Mafia are stories about a kind hearted boy growing alongside his companions. In if Episode of Mafia, the setting and developments are more serious, offering a more mature tone for viewers to enjoy. This is a work that fans of Iruma-kun will certainly enjoy, while also being accessible to viewers who are new to the series. Please look forward to it.
