Nai Muhinyi (无 Nai Muhinyi?) is the main character of the story. He is one of the first characters to appear in the story and meets Gareki during one of his thefts, causing the two to start their journey together.
Nai is a small boy (his age unconfirmed) with large, scarlet eyes, and pale features. He has short, white hair, somewhat resembling an albino, and ear-length spikes in the back. The two tips from his hair, which are sticking out above his ears, are lavender.
It's confirmed that Nai is a Niji (an animal), much to Gareki's embarrassment.
Nai is very kind and innocent, albeit quite naïve. Due to his dependence on Karoku, he tends to rely on those around him who are willing to lend him help- often getting him into trouble.
Nai does not know much about the world around him and is confused by very simple terms- not understanding the compliments he often receives, due to his otherworldliness. When Gareki first found him, he didn't know what blood was, referring to it as "red water." Despite this, he is also quite brave, as he dove to save an endangered animal and defended Karoku when they were attacked alone.
Nai is an all around pure and innocent character. He is eager to help, and incredibly loyal to those he calls his "friends."
A while after karoku moved to Niji Forest with his mother and father, karoku went out to take a look around Niji Forest. At some point,he fell asleep on the grass. There, While Nai was still a Mere Niji, he was wandering around with a wound from being attacked by another animal living in Niji Forest. There He stumbled upon karoku, whos hair was a pure crystal blue.
Karoku awoke to find Nai nibbling at his hair. Nai said that he had thought it was water and tried to eat it. Karoku took Nai to his 'home' in Niji Forest, and showed him to His Mother and Father. Karoku worked with his parents to take care of Nai and make sure he got his health back up after being injured so badly.
When Nai fully recovered, it is seen that Karoku took him outside with his parents, and Nai was already jumping high and moving around without any trouble. Soon enough, Karoku released Nai back into the Forest so he could live freely again now that he was completely healed.
It is shown that Nai grew an attachment to Karoku,even after he released him back into the forest. Nai constantly showed up outside where karoku was, and stayed with him and played with him. Cuddling up to him, like he was his father. Every day when Karoku showed up, Nai would be waiting for him in a certain spot. So, every day Karoku went outside to the same spot, and met nai there. They would hang out for hours and hours. And soon karoku Gave Nai his name.
Soon After, Karokus Dad went on a journey back into a town to get supplies and many other things. And he was caught up in a lovers quarrel between an abusive man and a woman. Ending up getting stabbed multiple times. Soon, Karoku and his mom found out about his fathers death. His mom began to go crazy slowly, and she kept herself locked away in the lab they had worked in together for years.
One day, Karoku went out to visit nai. And when he saw him, Karoku ran to him and cried with nai in his arms. Saying that he hoped nai never left him. And from afar, it is seen that His mom was watching them. Then one day, Karokus mom began acing sane again. Saying she would make dinner, and that she was only locked away because she was working on something. However, she was literally just acting. Somehow, she kept karoku in a sleep like state for a long time, not known if it was months or years.
He woke up to find that his nails were longer and he had needle markings on his arms, he was dizzy, and he could barely walk. Running to meet Nai, neither nai nor his mom were nowhere to be found.However, Karoku heard noises coming from inside the lab. Breaking open the door, he found his dads head in a perserved container. Then, he saw Nai's horn like things in a plate with pieces of his hair and blood on it. Karoku immediately thought the worst, his mom had killed Nai. Freaking out, he heard the noises again. Running to where a lump lay under a sheet, at first he thought it was his mom. Then he realized it didn't sound like her, and he wondered who was there.
Removing the sheet, Nai lay there in a sudden human form. Scarred with fear, and his hands wrapped completely in bandages, and he was shaking with fear. He saw karoku, and his eyes lit up with relief. But Nai didn't know how to speak, he just made noises and tried to reach for karoku. Karoku sat their shocked, and couldn't believe what he saw. But he recognized nai even in human form, and was surprised. Reaching for a notebook, Karoku saw notes on dna and cell splicing. He found out that his mom had used different cells from his dads head, and different cells from nai's Niji body, and brought them together trying to save his father.
Then his mom walks in, saying that she was able to create a new living being. After seeing that his mom had lost her mind, he yelled at her. Asking her why she did this, and that nai had nothing to do with this. And his mom said that his father was more important, and that he should know how she feels. That he must've felt the pain of knowing his father was dead. And that he should be able to understand her feelings. Karoku knew that if he argued with his mom and got into a fight with her, who knows what she do to nai when she was alone with him. Karoku pretended to agree with his mom, and she fell for it. Saying he was going to get supplies for dinner, he ran out and began searching for somewhere to hid him and nai. Then, he found a cave.
((More info coming next month))
he is able to hear people and things and track them down
Due to the fact that Nai is a Niji, his ears are incredibly sensitive to sound, giving him the ability to hear noises that are deemed inaudible to others.
Nai has showed the ability to sense the emotions of others. This ability has been seen through the series as Nai was able to sense the change in Yogi when he became Silver Yogi; as well when Gareki was sleeping and Nai was able to sense his mood. In Chapter 76, Nai was able to sense "a lot of warm things swirling around Gareki".
Gareki and Nai have a very close relationship, both showing great care and concern for each other. Although Gareki originally protected and provided for Nai purely for selfish reasons, he soon begins to take care of Nai and becomes his surrogate older brother. Nai also shows that he cares for Gareki when he tries to distance himself from him because Karoku asked him, "You don't want him to break, do you?" Because of this, Nai ended up pushing Gareki away in order to protect him. Gareki, not knowing Nai's true intentions, reacted negatively to this which resulted in Nai breaking out into an outburst of tears. However, the conflict was later resolved and Gareki and Nai are able become close again.
In the manga, Nai's relationship with Gareki is described as "attached to." This can be seen in Evening Swallow, when Gareki wanted to visit Karasuna and Nai insisted to come along even after Gareki said he couldn't. Yogi mentioned that Nai was probably scared of being away from Gareki, which lead him to saying yes. In Chapter 27, Gareki described his relationship with Nai as "a reluctant relationship." Gareki has also describes Nai as his lucky charm.
In Chapter 46, Gareki has a dream that the ghosts of Tsubaki and Yotaka are leading him somewhere. However, Nai appears in the dream and tries to lead him the other way, saying, "This way, Gareki," and "Tsubaki and Yotaka aren't there. Do your best in school and come back soon." The dream is interrupted as Shishi enters the room and wakes him. Earlier in the same chapter, Nai is seen having fallen asleep at Karoku's feet calling out "Gareki, over here!"
Their relationship is further explore in later chapters when Gareki decides to leave the school to go find Nai, who has mysteriously disappeared from the ship along with Karoku, even when he was warned that he wouldn't be able to return to the Circus course if he leaves. Soon after, Gareki was mysteriously teleported to a town where he spend his time searching for Nai. He eventually found Nai in a forest close to the town. While this is still unexplained, it shows that Nai and Gareki have an special connection as Gareki was teleported to a place close to Nai. In Chapter 74, Nai revealed to Gareki that he knew the real reason for why Gareki has left the school and while Nai was happy to know that Gareki came to save him, he was sad that he interfered with Gareki's studies. Gareki, trying to not make Nai feel guilty, said that he leaving the school and looking for him has no relation and that he won't do something that has no profit for him.
Yogi and Nai are good friends. Due to Yogi's childish and bubbly personality, he makes a wonderful playmate for Nai. He also protects Nai from any potential threats and/or danger. Nai is also a fan of Nyanperona, along with Yogi. It is also hinted that Nai enjoys eating Yogi's "Star Prince home-made yogurt."
Before Gareki left for Kuronomei, Yogi told Nai and Tsukumo both how lonely he always felt aboard the Second Ship before Nai and Gareki came along, stating that he always loved making friends with the children when he put on his Nyanperona costume, but always felt sad when it was time for the children to leave. After Gareki leaves, he is often shown feeling lonely. During one such instance, after an upsetting moment with Karoku, in Chapter 40 of the manga, Yogi sees Nai leaving Karoku's room and asks if he's alright, then tells Nai if he ever needs anything, to come and talk to him, which Nai promises to do so. However, Nai manages to sense Yogi is unhappy and asks if he's hurt, to which Yogi assures him he's fine. The interaction cheers both of them up.
Tsukumo is Nai's tutor and teaches him about the things that he is still unsure of. She is extremely kind and caring towards him and similar to Yogi as she always watches out for his safety and tries to keep him unharmed. Nai treasures Tsukumo as shown when she was being held at Smokey Mansion for a short time and Nai was extremely worried about her and then ecstatic when she finally returned.
In Chapter 45, Tsukumo gives Nai a stuffed Koketokage (Moss Frog) that she sewed together for him to remind him of the Moss Lizard he had become friends with in Vinto. Tsukumo worries Nai won't recognize what it was meant to be, but he instantly calls out what it is and thanks her for it.
Nai is nervous and frightened around Jiki because of his fake smile and dislike for Gareki. When others are in trouble however, they work together and Nai's fright disappears (at least temporarily).
All the information we have about them until now in the anime is they're somehow connected. Nai used to live with Karoku on the Niji forest and it is believed Karoku created him. Nai keeps looking for him. All he left behind was an old Circus ID.
- His name means nothing or not existing in Japanese.
- He seems to be able to tell whenever Yogi turns into his silver counterpart.
- He likes to bask in the sun and play hide-and-seek with the sheep.
- His favorite food is mochi onigiri, and he doesn't like lamb (because of the sheep in Circus).
- He dislikes studying lessons with Tsukumo, and can't understand the material when she is not there to help him.
- He likes to eat Yogi's "Star Prince home-made yogurt".
- His first kiss was a Sheep which jumped out at him from a passage.
