Dice rolls none of the beings in that universe see or know about
The dice just represents probability
They all act and move completely independent from these systems
"He died due to his videogame hp going to 0 therefore people cant drown or suffocate" Checks out
DnD sure as hell doesnt have any blood pressure and oxygen systems but this world very definitely does
This is generic anime rpg world with dice flavor nothing more
While most beings are unaware of the dice rolls, they are an actual intradiegetic thing that happens and oversee most actions and reactions.
Some things in D&D require a roll while others don’t. Trying to convince someone? Roll. Trying to attack this dude? Roll. Wanna go to the fountain and eat a hot dog? No need to roll.
While we, as readers, don't often see the exact result of every roll, you'd be aware that lots of them happen if you read the walls of explanation(checks, saving throws, damage, etc...).
Yukito attacked Sado’s vitals but did not deal enough damage to instantly kill him, but did cause him to bleed which would have inevitably led to his death by blood loss(bleeding, a D&D mechanic.) if not for him healing himself. In both real life and D&D, you won’t cause an instant death just by piercing someone in a vital organ but they will die if left as is.
Had Sado’s HP hit 0, he would have died.
"oxygen systems" are actually a thing in D&D, taking 5e as an example, a character can hold their breath for 1 + their Constitution modifier minutes and 30 seconds if their modifier is negative. (Source: Sado's book)
This is legitimately “D&D: The Manga” and could very well be mistaken for one of the author’s past homebrew campaigns with how closely it follows D&D’s mechanics, rules, bestiary and aura.
he is the big fat panda now
