It appears that the anime has shown some connection to DMC 5. Our little girl Patty has grown up and now going to invite Dante to attend her 18th birthday. IBut it appears that Dante doesn't want to show up and choose to fight the new Demon king that spreading evil across in one city instead.
Like what he promised, will he pursue to date the 18-year-old Patty? (In anime version, he promised that if she grew up and reached her adulthood he will consider to date her someday).
