Here we are talking about literal souls that use puppets to integrate in the natural world - it is called soul society for a reason - so everyone in there is doing cosplay and as such, cosplay cannot stop while in the natural world.
On the other hand, anyone could be the protagonist - Ichigo is a bully with nothing for friends or academic prowess, just a mild sob story for a character who is literally by absolute accident bestowed godly powers of a spirit.
The soul society generals and even rukia are akin to Sauron - ethereal beings that can focus their essence into any phisical object and imbue it with their essence while retaining their huge spiritual power that can be manifested into a Zampakto or a very powerful otherworldly weappon - which has a power to gain sentience and ascend to godhood - the white doppelganger of Ichigo is the sentient Zampakto and the Vasto Lorde Ichigo doppelganger is the Godhood ascended evolution of a soul.
OK I'm curious, do you guys prefer to play as the male main character from the series or as an anonymous original character?
Would not actually call a literal Angelus - should you follow those awesome comics - a choosing a nobody as your avatar.
Literally anyone could be coined out of Houco Mundo or the Soul society for a blank slate of a new protagonist or literally any human being out of the billions can become the totally undeserved clueless recipient of Rukia powers.
An anime h-game where you actually play as the series protagonist instead of fucking their girls? Rare asf.
The ”protagonist” is arguably the dad of Naruto - taller, slicker, more effeminate than Naruto or Boruto - total badass.
The story is of a nobody bully human who gets Rukia powers dropped onto his head. Nothing of value or interest there.
I hope the Orihime cosplay thing wasn't a one-off.
She likes it and she is a shape shifter, along with mastering the art of puppeteering meat puppets - grat times to come.
