Tier (ティエ, Tie) is one of the supporting characters of Summon Night: Craft Sword Monogatari Hajimari no Ishi. She is the only child of the local inkeepers of a town neighboring the protagonist's town, and is an ambitious child who will do anything for money. She also has an unrecruited yet immature affection for the player (a reason why she squabbles with Murno over a part of the plot, out of jealousy). She also (unsuccessfully) tries to woo Jade in a flirty way in hopes of getting paid.
On the the third day of the game she debuts as a young girl who forces the player to pay 200 boam to pass through the cave. Failure to comply to the bargain will disable the player from advancing through the game until they pay her.
