Finished Arrancar Renji. What? Backgrounds? Now that it’s complete, I should mention that the idea stems from junko222's writing that Rukongai souls are all “Hollow touched” as former Hollows, and so were not reborn inside the Court of Pure Souls, which also makes Rukongai souls potentially very powerful. Also her writing mentions that Hihiou Zabimaru's finisher resembles a cero, on top of the bankai already looking like a Hollow.
/geeking out stop me
Do I spot some fancy Inu Yasha necklace ehh ;) wink wink
Seven fangs for the seven fangs on Zabimaru’s shikai. Also his bankai has a fang necklace holding his shawl together (but the fangs are all red, hmm…)
