ティビー・パールバトン

A member of Anastasia Camp, and the youngest triplet. He is one of the three vice captains of the mercenary group Fang of Iron. Tivey tends to let Mimi and Hetaro do whatever they want unless it involves him and acts like a straight man to his siblings' actions. Contrary to their love of the outdoors, he prefers to stay indoors and gain knowledge, such as reading books in the corner, though even then he is bothered by Mimi. He is in charge of the Fang of Iron's clerical duties, which he excels at to the point where it's said that the mercenary group wouldn't function correctly without him. Because of this, he sometimes helps Anastasia with her business, however he refuses her offers to have him permanently move to her company. [From Re:Zero Wiki]
