for a while now I've updated favgroup #26983 (has nsfw) to keep track of images referencing that official Tharja statuette of her leaning on a book stack (see: Fandom wiki link about it)
obviously these are searchable enough with some combination of Tharja (Fire Emblem) + leaning forward / bent over + book stack
but I was thinking lately could a general tag for this hurt? maybe Tharja (Good smile) could be the name since it's the official name of the collectible
there's also the option of making a collection pool for these but I don't think that'd make much sense compared to a gen tag. it's not that subjective what qualifies.
