Real-world references
In order to counterattack Shoutmon X7, Laylamon casts a magic circle. Part of the inner circle has DigiCode reading "えろいむえっさいむわれはもとめうったえたりー" (エロイムエッサイム、我は求め訴えたり,Eroimu Essaimu, ware ha motome uttaetari?), which itself is a translation of the black magic incantation "Eloim, Essaim, frugativi et appellavi", found in the grimoire La Poule Noire and popularized in Japan by the manga series Akuma-kun.
