Character: hiromi aran
From the DA description of post #1078409: Fuzzy dragon zero suit time! Comm for awb26~ Their girl Hiromi. No further source is given. "Aran" is not mentioned on that page. All other posts have dead or unhelpful sources.
It is possible the _aran suffix is an invention to describe the costume? That is, this character is unrelated to samus_aran aside from cosplay. Hopefully Blind Guardian knew what they were doing when they created the tag. A more accurate name might be hiromi_(awb25).
