BUR #61590 has been approved by @evazion.
rename sasaki_rico_(root_letter) -> sasaki_riko
create alias sasaki_rico_(voice_actor) -> sasaki_rico
This one has been bugging me for a while, but apparently Root Letter's Sasaki Riko is spelled Riko, not Rico
Additionally, Sasaki Rico (Root Letter) has gotten precisely 1 post in the game's 10-year (as of last week) existence, while Sasaki Rico (Voice Actor) is an active voice actress with actual fans drawing actual fanart, hence the current post difference. I think these tags will be fine without a qualifier.
