Krile is kind and intelligent, and highly knowledgeable in a number of fields. She can read people and enjoys teasing others. She brings up Alphinaud's past to embarrass him, notes Thancred Waters's affection for Minfilia, tricks Unukalhai into dropping his stoic facade, and likens Y'shtola Rhul to her master, Matoya, which annoys the usually calm Miqo'te. Nonetheless, Krile cares for her friends deeply, working tirelessly to aid them. She is quick to apologize to Thancred and Unukalhai for her probing when they take offense, explaining she only does this to get a better sense of her companions' personalities and motivations, so that it is easier to trust them.

Krile was Alphinaud's mentor in the Sharlayan Academy, and though she teases him, she does think fondly of him and approves of how he has matured, knowing he would come rescue her if she were in danger. She has a great deal of patience and a level head, but on rare occasions can lose her cool and even the Warrior of Light is not beyond her scolding.

Krile holds misgivings towards the nation of Sharlayan and its policy of non-intervention, finding the Forum's refusal to aid the Eorzean nations during the Umbral Calamity and its mass exodus following the Empire's conquest to be their most shameful acts. In contrast, she holds her grandfather Galuf in the highest esteem, safeguarding his legacy being her primary concern. She was incensed when a Forum member denounced her for her association with the Scions and claimed that Galuf would be ashamed of her; Krile argued her grandfather had wished to protect the world and his fellow man.

Krile regrets not being as apt in combat as her fellow Scions, but to compensate focuses on her own talents and how she can use them to aid her friends. After watching the rest of the Scions confront world-ending dangers, she doubles her resolve to better herself and walk her path. This motivated her to take up the art of the pictomancer, as much like G'raha Tia, she admits she does not want to be "left behind" again.
