In this world an apocalypse has just started. The apocalypse has just started it brings both dangers such as monsters and other humans but also blessings like abilities and a universal system given to all humans and future humans.
when the apocalypse starts everyone receives an ability abilities are ranked as follows:
(all s ranked and above abilities can be really weird or specific)
SSS: very few people have an sss ability or will ever have one only one in every billion people received one. and the population at the start of the apocalypse was 10 billion. these powers can completely change a portion of reality like sinking an entire country or causing biblical blights.
SS: much weaker than SSS but a lot more common but still pretty rare these abilities normally would belong to leaders and maybe one other person per settlement. The type of abilities this rank holds are things like causing lighting storms or raising magma from the ground and even making entire pocket dimensions.
S: these are really special powers normally include very personal powers like hyper regeneration or very powerful control of an element (water, earth, fire, air, lighting, ice, etc.)
AA: more common than any s rank but still reserved for a select few. normally combined elemental ability like water/ice and Fire/lightning. also were many useful support abilities are.
A: some of the strongest warrior and fighters have an A rank ability they can be pretty normal like elemental powers or moderate telekinesis and sometimes they can be unique like conjuring strong summons.
B: by far the most common fighter rank it contains some rare or unique abilities but it is not common and it's normally just basic constitution power or good proficiency in an area like melee or ranged combat.
C: the rank most people got this is were elemental abilities become useful and powers pack a punch. an important but very common power is insight which lies in this rank insight gives people to see and write down someones status
D: weak or limited powers normally not combative unless trained intensely.
E: not much more than making a spark or slightly more resilient body.
(note there are people with two or even 3 starter abilities then many people gain more abilities through titles)
Numbers are a measure of how the ability has progressed due to practice so if both people have the same power at a rank of B then the one that practiced more might have B20 and the other night have just B in essence numbers are a measure of how strong the ability is due to practice making it stronger.
titles are achieved through either fullfilling requirements and or being called a certain name titles can give abilities and buffs but negative titles have a mix of good/bad traits. an example is a type of title called thrower so say knife thrower title will give you hit the mark an A title ability and some proficiency in throwing knives. also some titles are for a single person while others can be achieved by anyone and some titles can be passed or partially passed down through the generations.
a normal person with a single C rank ability status might look something like this
....
name:[blank]
age: [blank]
titles: none
abilities: wind knife C
Strength 10 normal
Speed 10 normal
Stamina 5 human
Perception 20 intermediate
Endurance 10 normal
.....
human:5-9= basic human before apocalypse
normal:10-19= the average power level people started with after the beginning of the apocalypse
intermediate:20-49= good level many people have at least one stat at this level but this is normally the limit for many noncombatants except for special cases.
advanced:50-75= just a few special people work hard enough to train to this level most are just gifted with good titles and or abilities.
peak human level:76-99= this is were the stat has such an influence it is basically a B ranked ability.
God:100= this is were only strong and or gifted hard workers are. people with this rank are given a title with an ability according to the stat and are also given a godhood fragment which is basically a strong special blessing.
-------------------------------------
everyone on earth became infertile for 10 years in order to adjust to the new world.
in the beginning was/is a tutorial phase were people within an area must survive for one month the areas are
normally schools, blocks, apartments etc.
the tutorial phase increases difficulty ending with a B ranked devil.
once the tutorial end a few areas are pulled together and go through a second tutorial less strong monsters but many plus the threat of new humans. it only ends once 100'000 monsters or 10'000 humans die to humans.
once that ended many have/will make settlements/mini kingdoms.
