Ruca Milda (ルカ・ミルダ,Ruka Miruda?) is the main protagonist of Tales of Innocence. He is the reincarnation of the Sensus general Asura. Ruca is the son of a merchant and lives in Regnum's capital city that shares its name. He is a shy honors student who is constantly picked on by his classmates. On his way back from a shop, he meets a hungry Illia Animi, and later, he and Illia encounter a couple of Avatar hunters who attempt to capture the two.
Being the son of a rich merchant, Ruca dresses in a rather formal manner. He wears a yellow muffler stuffed into his blue suit, with dark blue trousers and a pair of brown boots. When he obtains a broadsword, he has brown suspenders around his chest to hold the sheath on his back. As he is an honor student, he is intelligent and able to observe and understand situations quickly. However, because of his shyness, he is constantly bullied by his classmates.
When they arrive at the inner levels of the dungeon, they find Veigue fighting with the CraymelCelsius to save Claire Bennett. After fighting Celsius and saving Claire, he returns to the ship with the others. Ruca and Illia then go on another mission to the canyon with the player, where they find a flower that is used in one of Raine Sage's experiments. Ruca's job class in the game is a Magic Knight, and the weapon he uses throughout the entire game is the average "Broad Sword".
Tales of the Heroes: Twin Brave
Ruca appears in Tales of the Heroes: Twin Brave as a playable character in the comical scenario, in which he continues to run errands for other Tales characters. In the serious scenario, he and Spada travel to the World Tree to investigate the disease that attacked his town.
In Tales of Xillia 2, Ruca is mentioned in the job, "Fruit n' Cheese? Yes, Please!", in which he rewards the player with the "Sealed Innocence" weapon in exchange for "Fruit n' Cheese (Small)".
