Several characters have fighting styles and weapons that pay homage to the Devil May Cry series:
• One of Masamune's sets of swords is based on Alastor, one of Dante's swords.
• One of Yukimura's pairs of spears is based on the Sword of Sparda.
• One of Nouhime's sets of twin pistols is based on Ebony & Ivory, Dante's signature guns.
• Mitsunari's fighting style bears similarities to Vergil's.
• One of Itsuki's skills, Matsuribayashi, bears similarities to one of Nero's attacks.
