I know it sounds crazy but hear me out, do you think Bleach is the masculity Sailor Moon, was Kubo a fan after all I have seen SM references on the show, for example one of the outfits that Yuzu made for Kon a Sailor Senshi outfit?
Here is some simularities, it starts out with the main character living a nomal (besides Ichigo seeing ghosts) but it is soon discovered they have special powers that they didn't know about, and amoung those people that have the power, they are special even among them and are the choosen ones.
They start out basicly on their own fighting villains, they shortly others join them and they become leaders of a team, Usagi has the other four Senshis, Ichigo hads Orihime, Uryu, and Chad. Than later Rukia and Renji though he loses Orihime as his allie as she is captured by Aizen.
Also in the beginning you see a lot of the main character's family and classmates. But as the series progressive their roles shrink and they slowly become forgotten.
On Bleach they clinse the Hollows and allow them to be reborn and giving a second chance. In Sailor Moon they sort of did that to some of the villains, they forgave them and let them be reborn or memories erased and start a new.
The differences in what might defines between men and women is, while Usagi and friends didn't want to fight but did if they had to, Ichigo and friends they love to fight. (except for Orihime)
Last but not least, both series had talking cats.
