Currently we have eve_(ib) and gary_(ib) tags for Ib main characters.
On game's website aforementioned characters are named Ib and Garry, respectively.
Therefore, I propose the following tag renames and/or aliases:
eve_(ib) -> ib_(character)
gary_(ib) -> garry_(ib)
Or something along these lines.
EDIT: Grammar.
