Contrary to her dainty, petite appearance, Effie wields tremendous physical strength that easily allows her to perform astounding feats that regular people are unable to accomplish, including bench-pressing tree trunks and crushing whole fruits with her bare hands. Taking pride in the physical strength that she possesses, Effie maintains her physique through rigorous training regimes that she forces herself to undergo. To this end, Effie is known to cultivate the habit of ignoring all external forms of distractions whenever she is in the midst of her training, to the point of blatantly disregarding the attempts of others to engage her in conversation. Her C support with Odin proves this fact, where the intense focus that she directs to her squat training causes her to be completely unaware of his attempts to capture her attention. This same support also reveals Effie to be eager for self-improvement, constantly seeking out new methods to enhance her physique. Odin's mention of a new training technique to instantaneously double one's strength proves this, as this piques her interest sufficiently to direct her attention from her squat training to him.
