Not so much afraid to pitch as much as 'This randomly popped into my head and I gotta share this with the world before it's lost for good'

Danganronpa and YGO crossover. Lifepoints are your literal life- get down to 0 and you die by some kinda poison bracelet or something. You can't recover life in between duels, but surrendering a duel doesn't drop your life to 0, if the other accepts your surrender that is. If someone dies by the duel, a class trial is held to determine who dueled the other to death. 

I have no idea how it would work- heck, IF it would work. I just felt like sharing my random brain fart.
