Isaac, who views Dante as a rival for the affections of his crush Cindy, follows him one night into a nightclub, only to be thrown out after getting caught in the women's restroom. He then tries to follow him again, but gets chased off by Patty and eventually witnesses Dante eliminate a horde of demons posing as Mafia soldiers. Breaking into Devil May Cry, he runs into Sid, who gives him a small bell before allowing him to escape. Isaac is attacked by a demon, but Dante kills it. He decides to flee to the countryside, but Dante intercepts him and reveals that the bell is, in fact, a summoning charm. He then summons and kills several more demons before destroying the bell with a single shot. Before leaving, he encourages Isaac to pursue Cindy. Isaac later visits Dante at the diner where Cindy works and orders the same sundae he's eating, which Dante interprets as an unwanted display of admiration.
