Re-reading this after a while, so where does Heinz I go? Did he canceled the creation after Heinz died and just use Heinz II? So he could use the extra slot? I keep thinking about it lmao
Think of it kind of like a pokemon nuzlock game. However, unlike the game the as the MC levels up he gets more slots for new pokemon on his team. Hans was the starter and Heinz is in the second slot. Since it's a nuzlocke when the pokemon dies it's gone. So Heinz I (zubat with a tough nature) died and Heinz II (zubat with hasty nature) took his slot on the team and evolved into a vampire (golbat) and eventually became a sacred blood (crobat).
The female lead (if I remember correctly) have pink hair. Originally, she is like a game dev or something but wake up as a side character in her game. She then kind of becoming one of secretly strong alchemist/potion maker.
The ML is cursed (?) He can't sleep or if he does the disaster will come. Because of this he was confined, chained. And so, he need a huge amount of sleep resistance (?) potion to keep himself awake.
The FL became his personal potion maker and they bicker a lot. I only remembered until that part help......
