ENA is the protagonist of ENA season one.

She is a blue and yellow entity who is often seen experiencing sudden changes in emotion.

ENA’s appearance changes based on which emotion she is feeling. The blue side of her face represents sadness, and the yellow side is happiness. Other than happy and sad, she also can be “drunk”, which results in more appearance changes.

In the third episode of ENA, Temptation Stairway, she gains a full sadness form. While in this state, she sobs and mumbles incoherent things.

ENA HAPPY

While in happy mode, ENA is generally polite to others. She is usually seen smiling, and standing with her knees bent inwards. This is presumably ENA's default state. At the end of Temptation Stairway ENA's blue side is erased, making her only happy.
