Yuno Gasai Character Analysis (Part 1)

This post was originally combined with my Yukiteru (Yuki) Character Analysis, but that post was too long, so I split up the analyses for Yuki and Yuno. Still, Yuno’s character analysis was a little too long. As a result, it’s been divided into two parts. These posts are being edited still, so try to forgive any mistakes you find.

Now, Yuno Gasai is a popular character, but some people just love her for being a yandere and fail to think about her character at any depth. In this section, we’ll examine her closely. Let’s begin with a breakdown of Yuno’s story. Then we’ll identify a rough idea of her personality when she’s in a stable state. In part 2, we’ll look at questions and answers about Yuno.

1. Yuno’s Story

Not originally a member of the family, Yuno was adopted by Saika (the wife) and Ushio (the husband) Gasai. We don’t know at what age she was adopted; some fans believe it was when Yuno was still a baby, and others believe it wasn’t until the time she started middle school. It’s possible that she temporarily lived in foster homes or an orphanage of some kind. This could have predisposed her to having less empathy than a neurotypical person. Regardless, no child could be prepared for the agony to come.

She suffered neglect, mental or emotional abuse, and physical abuse at the hands of her parents. It’s implied that Ushio is a more stable and mentally well individual than Saika. Though he was neglectful of his family, he wasn’t openly abusive like his wife. The full extent of the abuse is unknown, but we can fathom how serious it was from information gathered from episode 18.

Yuno was forced to keep tallies and statistics of the number of times she talked back, was late for school, did poorly on a grade report, and possibly more. It was normal for Saika to lock Yuno up in a dog cage, scolding her fiercely and denying her meals. Saika was mentally unstable, at least during Yuno’s middle school years, unable to deal with the emotional and often physical absence of her husband. Mentally abusive, Saika is shown in episode 24 guilt-tripping Yuno and implicitly threatening to kill herself because of her daughter’s perceived misbehavior and her husband’s abandonment.

The abuse escalated to the point of putting Gasai’s life in danger. In episode 24, the Third World’s Yuno, about age 12 or 13, nearly chokes to death from trying to eat tatami, the straw fibers that make up floor coverings in traditional Japanese homes. The young girl was out of her mind from starvation and covered in vomit. Perhaps this instance was the culmination of all the mistreatment, a one-time catastrophe. But no, it must have happened many times in the next year. Or else why would Yuno lock up her parents a whole year after the incident in question?

Around age 14, the second year of middle school, the First World’s Yuno drugged her parents with sleeping pills. She moved them into the dog cage, keeping them there anywhere from a few days to a few months. Mr. and Mrs. Gasai died from neglect and slow weakening; Yuno didn’t actually intend to kill them. (See the Questions and Answers for more discussion of this.)

Yuno already knew Yukki from school (and had started stalking him) before the First World’s survival game. That’s how she ended up with the “Yukiteru Diary” once the battle-royale began. Details about the first version of the death matches are not provided in the anime. However, the extremely brief flashback hints in episode 23 give us some clues. We can see images of the First World, where Yuno strangled the Fifth and stabbed the Twelfth with a knife, and Yukki fought the Sevenths with a knife and shot the Ninth during the school bombing.

In the First World, it seems the game went much quicker and smoother, with Yuno and Yukki winning nearly every fight. They worked together with their perfectly compatible diaries, and Yukki trusted all of Yuno’s strategies from the beginning. Things worked out this way because in the First World, Yukki didn’t find out (until much later anyway) that Yuno killed her parents. Due to Yukiteru finding this out in the Second World before he could fully trust Yuno, the whole future took a different direction. Yukiteru doubted and resisted Yuno for almost the entirety of the Second World’s survival game. But as for the first time, Yuno and Yukki easily ended up as the last ones standing. 

As you probably recall, Yuno and Yukki disagreed about how to handle things. Yukki wanted to commit a double suicide so that they wouldn’t have to kill each other. But this would mean there would be no God, and the First World and everything in it would be destroyed. It made a lot more sense to Yuno to simply become God, save the First World, and then resurrect Yukiteru. So she tried. She pretended to die with Yukki, but spit out the poison pills after Yukki died. Then the worst imaginable outcome for Yuno happened. Even as God of Causality, Space, and Time, she could not bring Yukiteru’s soul back from the dead.  

After correcting the causality of the First World so it would go on till its natural end, Yuno time-leaped to the past. She then murdered the Second World’s Yuno. These acts were done under the guidance of Murmur, who also manipulated Yuno’s memories throughout the Second World’s survival game. This is where the anime begins. Managing to win this time was much tougher because, in episode 3, Yukki discovered the bodies of Ushio and Saika and began to doubt Yuno.

Despite the difficulty, Yuno still ended up right where she wanted to be. (This is only because she manipulated Yukki so atrociously, lying to him and making him kill his own friends.) The whole time, Yuno had hoped and prayed that Yukki would become God and end her unhappy existence. But he broke his promise and refused to kill her, instead suggesting double suicide. So Yuno decided to time-leap to the past, murder the Third World’s Yuno, and play the survival game again with that world’s Yukki. This required killing the Second World’s Yukki, though.

Yuno could not bring herself to stab the Yukiteru of the Second World, no matter how she tried. For more info about that, read the Question and Answer section. Not being able to end Yukki was her undoing, but it was also her redemption. For expansion on this topic, please see Part 4: Thematic Analysis. Yuno let Yukki win the survival game by stabbing and killing herself. 


2. Yuno’s Personality

Technically, it’s impossible to give a fictional character a personality type meant for real people. Still, it’s something I enjoy doing to understand characters a little better.

Of all the characters I’ve written about, I believe Yuno is the hardest one to type. This is partly because she has mental issues and is almost always seen in extreme situations. I’ll give this a shot, though. Yuno seems to be a reserved individual, quiet but forceful around others, unexperienced with groups, and reluctant to be a team player. I think this makes her an introvert. Placing emotions over logic, Gasai is mostly a Feeler and not a Thinker. She falls into the J (judging) category because she is more strategic and organized than the P types (perceivers). 

What about intuition versus sensing? This is the toughest call to make, because Yuno seems to rely on practical knowledge and sharp gut intuition about equally. If I had to pick, I’d say she’s an N and not an S because INFJ sounds a little more like her than ISFJ when you read about them. I do think Gasai is more instinct-natured than she is attuned with physical reality, as well as more imaginative than traditionally practical. With that in mind, we can say Yuno is an INFJ. This is one of the rarest of the 16 personalities. It’s also one of the most complex.

Let’s look at some facts about INFJs. They stick to things until they’re done. They are so adept at reading people and situations that it’s be unsettling. INFJs want to be perfect, and judge themselves harshly. They like to plan ahead and get things done in orderly or systematic ways. An INFJ is usually very warm, gentle, and caring, but at the same time highly opinionated and stubborn. A turbulent type INFJ is likely to become obsessive and brooding.

Strengths of the INFJ include wanting to help people and treat others well, ability to communicate convincingly, and being extremely passionate, creative, and insightful. Weaknesses are burning out easily due to so much passion, being too perfectionistic, emotionally and physically shutting people out, and becoming tremendously sensitive or angry when challenged.  

Two of the most prominent features of the INFJ type are the desire to be altruistic and the great dedication they have to their selected loved ones. Yuno may fit the second description, if we assume that Yukki is her only loved one. Still, she is far from being altruistic or helpful toward most people.This is what I meant by using the MBTI as a rough guide. Gasai’s ability to kill and the way she stalks Yukiteru are parts of her insanity, and are not reflected in any of the 16 Myers-Briggs types. However, it’s true that INFJs can become obsessive about a person they love or an idea they fight for. They always need to have a cause, which is more important to them than anything else. For Yuno, that cause is being together with Yukki.

Remember that Gasai has different “sides” to her—while not meeting the criteria for multiple personalities (now called Dissociative Identity Disorder), she maintains at least three central “selves.” The first is a gentle and childlike self, the second is a cold and merciless self, and the third has overlapping of both, with warmth, impatience, vulnerability, and deceitfulness. The gentler side lets Yuno show her love, express her worries, and interact with people socially (such as Rea Amano). The tough side lets her shut off empathy, think up strategies, and read situations.

Thank you so much for reading! I truly appreciate it. Next time, in my Yuno Analysis part 2, we’ll handle specific questions about Yuno and my answers. Take care now!
