User blog comment:CNBA3/Tier Harribel's Name./@comment-25690287-20160314193759

Tier is German for beast. Given that she's leader of the Tres Bestias it makes sense.

Harribel is a corruption of Harry Bell. All the Espada are named after famous architects. Harry Bell Measures was an English architect.

So it's not a real name but it's based off a mix of German and English.
