So I was thinking of writing a fanfiction story for bleach and the number of hollows that exist is giving me trouble. I need a reasonable number that is backed up by evidence as to how many hollows there are in total. Not counting the devoured souls but rather what we see as a one person. In simple words, 1 Menos is 1 hollow. Not 100+ hollows or souls. Also, what are the balance ratios of the material world and the spirit worlds that souls and hollows need to be kept at? Like 1 human for every 4 hollows or 1 human for every 3 soul reapers? I need this because I planned on making Ichigo commit a massive genocide of hollows and I need to know how that will affect everyone else and how many hollows he could kill reasonably. Please help as soon as you can.
most of that has never been touched upon in any detail. The only thing that I can remember is that Mayuri killed 25-30 thousand people in Rukongai during the final arc's early stages to restore the balance after the Wandenreich attacked Hueco Mundo.
So you would have to make a best guess at all the rest. Id suggest look up the real world stats on natural death rate and assume (making up a number here) 90% of them would be sent to Soul Society and the rest turn to Hollow.
I wrote several Arrancars Story, so you can't put a number of Hollows because there endless, since they dead and are born without end. Trust me Hollow have no number you can up down one they just excite in many like humans. Can't up a number of humans, since we all death and new ones are born too. Think of that for the hollows too.
