Completely different games.
Akiba's Trip: Hellbound & Debriefed = Akiba's Trip 1 (port from PSP)
Akiba's Trip: Undead & Undressed = Akiba's Trip 2 (port from PS Vita)

To be more accurate, they have the same initial premise, but with two completely different stories and settings. They're completely separate from one another in terms of story.
