User blog comment:Martialmaniac/Hina's former name/@comment-32818639-20180328204932

Some time ago I tried to find the source but I could not, something must have gone unnoticed. However, although not very useful information, her first name (ヒリン, Hirin) appears in the credits of episode 81 (for example) and is her name in the official anime site (without the later name as in Leol's case); also, in Hunter × Hunter Battle Collection she has both names, depending on the card.

The Viz version may have omitted her name in some way (note: I did not find it in Japanese text either) or this can be an anime only thing, although in this case it is strange to be so difficult to find. Another possibility is to be anime only but with her name changing from Hirin to Hina solely in the credits (which would be the weirdest thing).
