This lady minds the Central Tower library in Generation 2. She's a lot like the original librarian, but redesigned in many subtle ways. She has different glasses and a new uniform. Most importantly to her however, is that she has her right thumb! The original librarian was missing that digit.
Librarian is so much of a stereotypical profession that they couldn't invent anything new, lol. Anyway they should have updated everyone like they did here.
Nice redesign work for Phantasy Star Generation 2 ! And the thumb is back, hooray :!!! In fact, the original design of the librarian was great, and it is too here as it's quasi the same !
