Introverted Intuition (Ni): Yuno is very good at perceiving other people around her’s actions, especially Yuuki. Often times, it seems like ideas just come to her rather than focusing on reality and coming up with them. She has a mystical aura pinned to her which Yuuki, being a likely Si user, picks up on himself. However, she often loses touch with reality which is highly reflected in her impulsive actions.
Extroverted Feeling (Fe): Her feelings toward Yuuki and how she treats him demonstrate her compassion for the people around her, although at times she may seem insensitive and unwavered by other’s emotions. When she tries to shelter Yuuki from the truth about the game, she is ultimately trying to protect his feelings.
Introverted Thinking (Ti): Although Yuno at times may seem impulsive, her plans are carried out by quick thinking inside her own mind. She’s intelligient and fast to solve problems and find solutions.
Extroverted Sensing (Se): Yuno has a very weak Se function, mainly because it is shown throughout the series of her loosing grip with reality and what is true. She often times could be called “delusional” since she is so caught up in her own world to realize the truth in the real world.
