Yuni is a young apprentice. He was originally a student under Cucrow, but his time there left deep scars on his confidence. By the time he appears in the story, Yuni is already someone who doubts himself constantly and believes he has no talent, no courage, and nothing special to offer.
His story centers around one goal. He just wants to pass the second test of the Pentacle of Proving, the Sincerity of the Shield. The thing is, this is not his first attempt. Yuni has already failed the test twice before.
The biggest reason for this comes from his past. His master, Cucrow, treated him poorly. Instead of supporting him, Cucrow gave up on him completely. When Yuni took the test, Cucrow did not even stay to watch. He simply assumed Yuni would fail and left him behind. In Yuni's first and second tries, Cucrow stood and waited at the exit, only for Yuni to fail, and now he completely gave up. Over time, this treatment shaped how Yuni sees himself.
The clearest result of this is Yuni's mindset. He believes that if he can just pass the test, everything will change. He imagines his master finally praising him and calling him his star apprentice. But at the same time, he feels like that outcome is impossible.
His biggest weakness is his lack of confidence. Yuni is extremely anxious and constantly aware of his own flaws. When people are watching him, he cannot perform properly. Due to pressure, his hands shake, his body trembles, and his lines become messy. Even simple spells fail because of this pressure. But when he is alone, he can focus and draw cleanly.
Because of this, he relies heavily on studying. He spends his time memorizing how other witches solve problems. He believes that if he follows the correct method exactly, he might succeed. To him, there is only one right way to do things. If he deviates from it, he thinks he will fail again.
This mindset is challenged during his third attempt at the test. During the Sincerity of the Shield, Yuni works alongside Agott and Riche under the supervision of Alaira. Early on, Yuni clashes with Riche. He insists on following the textbook method, while Riche believes in using her own unique approach. The turning point comes when Riche's method works. For the first time, Yuni realizes that there is not just one correct way to succeed. This idea begins to break the thinking that has been holding him back.
The sad truth is that he just wants to finally get past this challenge. On his third try, he even drew all the spells, the right answers, ahead of time.
His biggest breakthrough comes thanks to Riche's help. Riche tells him he does not need to become someone else to pass. He just needs to find a way to be himself. Since he can draw properly when he is alone, he should create a way to achieve that condition.
This breakthrough also reveals one of his strengths. The fact that he cannot do things the same way as others is not just a weakness. It might be the key to what makes him unique. Inspired by this, Yuni notices that no one is laughing at him or making fun of him. He realizes the only curse on him is coming from himself, his own reflection.
This became his most important moment. Yuni understands that it's not others holding him back. It's himself. His fear, doubt, and self-hate are like a curse he put on his own mind.
Using this realization, he creates a new solution. He combines multiple seals into one. He uses elements from a mirror cloak of borrowed shade, concealment signs, and reflection signs. But instead of copying the original design, he changes it. He removes the mirror aspect of the spell and focuses only on gathering shadows. This creates a cloak that lets him blend into the darkness. By hiding himself from view, Yuni removes the pressure of being watched. Now, he can draw calmly, just like when he is alone. He can use magic freely without being seen. More importantly, this moment changes how he sees himself. He begins to hate himself a little less.
But his story takes a darker turn. During an incident caused by the Brimmed Caps to force Coco to perform forbidden magic, Yuni is forced into a forbidden transformation and becomes a black scale wolf. This changes his life completely.
Naturally, Riche and her friends try to save him. Coco, Riche, Tetia, and Agott attempt to reverse the transformation using an inverted scale wolf curse. But it does not work the way they expected. In the end, a Brimmed Cap witch named Egwin restores him to human form using a special necklace. But this is only temporary. Thinking it won't help if it's not Coco and the girls who save Yuni, Egwin takes off the necklace, making Yuni transform again. Luckily, Coco had already stolen the necklace using a grasping wind spell.
The necklace acts as a contraption that suppresses the curse. If Yuni removes it, he turns back into a scale wolf, because the original spell is still active. Basically, he's not back to normal completely.
Because of the danger surrounding him, Yuni cannot return to normal society. The Knights of Morales would erase his memories if they found him. With the help of Riche's magic, he leaves with Alaira, who chooses to protect him even if it means abandoning her old life. Until they find a way to remove the seal, they have to hide.
That's why another major influence on Yuni is Alaira. Unlike the fraud Cucrow, Alaira supports him and sets a positive example in his life. Through her guidance, Yuni slowly starts to understand that taking the easy way out will not help him grow. He begins to build confidence little by little.
Before leaving, Yuni and Riche made a promise to each other. When they meet again and Yuni is back to his true self, they will show each other the magic they've learned.
One surprising detail about his new life is that Yuni actually prefers staying in his scale wolf form. In that form, he feels more confident. People and animals stay away from him out of fear, and he can move faster. Even though the scales can cause others pain, he can knock them away by running.
But this creates another problem. Alaira encourages him that while it is okay to find a place to hide, he should also learn to create safety for himself using his own strength. Inspired by both Alaira and Riche, Yuni makes a decision. He wants to become his best self, not by running away, but by growing stronger. And that decision becomes the next step in his journey as a witch.
