What I love is the logic of it all. I'm just imagining it Akame: "Hi, I was the first demon I ever defeated to defeat one of the 12 moons! Demons that can defeat even Hashira." Demon Slayer Corps: "Yes, I'm sorry, you get the lowest rank there is even though you defeated a moon!"
Once it says your lower has reached it's limit, you can get more health by drinking the blood. Like drinking enough blood will give you nine rows of hearts
ik you said you'd stop playing solo leveling mods but theres a new one by cromta and its actually pretty sick, but its extremely grindy so you'd have to make it a multi-part series
