Cynonari

Cynonari is the slash ship between Cyno and Tighnari from the Genshin Impact fandom.

Canon
Cyno and Tighnari are shown to be close friends. They mutually trust each other, and often ask each other for assistance in various matters. They share a lot of similarities, as the two of them both take their jobs seriously and are shown to care deeply for others even though it may seem at first that they aren't as caring. Both of them are also graduates from the Akademiya, although they did not attend school at the same time. Cyno works as the General Mahamatra, who's duty is to enforce the Akademiya's rules and regulations, while Tighnari works as a Forest Watcher, who helps maintain and protect Avidya Forest. They are both quite intimidating with their jobs, with people cowering in fear at the sight of the General Mahamatra and Tighnari giving stern lectures to anyone who does foolish things in the rainforest. Cyno lives in Sumeru City and Tighnari lives in Gandharva Ville, but Cyno will often come visit to have dinner with his friend.

Character Story Profile
Tighnari's character story 4 mentions how he first met Cyno during his days as an Akademiya student. He became very popular amongst the students, causing all kinds of students to come up to him wanting to collaborate. Cyno as the General Mahamatra saw this as Tighnari forming factions and gathering forces, which he deemed as harbingers of academic corruption. However, after Cyno spent time observing and spending time with Tighnari, he realized the student had no ill intentions and while he was willing to collaborate with others, his focus was on his own studies. Cyno deemed the threat as resolved, but due to the pure impression Tighnari had on him he ended up letting down his guard and they became friends. This also led to Cyno later entrusting Collei in Tighnari's care.

King Deshret and the Three Magi
In the Sumeru Archon Quest Act IV, Tighnari is brought up by the traveler and Paimon briefly while talking about incense with Cyno. Cyno makes a note about them knowing Tighnari, to which Paimon asks if they are friends. He responds with a yes. Paimon then asks if Tighnari lectured him as he had with her and the traveler, and Cyno says there's no need for him to. Cyno asks if they first smelled the incense at Tighnari's house, to which traveler says no.

Akasha Pulses, the Kalpa Flame Rises
As part of the plan to free Nahida, Cyno tells the traveler that they will need to introduce Dehya to Tighnari. The traveler asks if it will be okay to not tell Tighnari the full plan, and are worried that he will refuse to help. However, Cyno is confident that Tighnari will help as the two of them have a very close relationship and know each other very well. Cyno has no doubts Tighnari would be willing to join their side through his message alone. He also adds on that Tighnari is their best option for this matter.

The traveler and Dehya go to Pardis Dhyai to meet up with Tighnari. They ask him about the Doctor, and Dehya apologizes for asking such things when they had only just met. She says the only thing they can say is that they are working with Cyno. Tighnari says that their secrecy is fine, and that he will assist anyway he can. Dehya laughs at this, pointing out how quickly he joined their side with just Cyno's name. She asks why he isn't worried about them lying, to which Tighnari responds saying that he has no reason to believe she, the traveler, or Cyno would deceive him. Tighnari proceeds to explain to them a conversation he had with the Doctor. The trio thank him for the information, and Dehya apologizes once again for their secrecy. Tighnari says it is fine, and that he has an obligation to do so as he thinks he may have started all of this.

The game shows a flashback, revealing Cyno and Tighnari talking together alone at Pardis Dhyai. Tighnari tells the other about how his master wrote him several letters. He explains that there is something unusual about the latest batch of letters, which made him worry that something has happened to his master. Tighnari asks Cyno to investigate this matter, but only if he can keep himself safe and tells him to withdraw immediately at the first hint of danger. Cyno agrees, and states that he will leave the Akademiya entirely if the situation becomes critical. He tells Tighnari to be careful of the Akademiya, to which Tighnari says he is surprised to be told such a thing by the General Mahamatra. The flashback ends after they share a few more words.

Tighnari says this conversation is why he is willing to help them despite their secrecy. He also asks the traveler to pass on a message to Cyno- to trust himself. Eventually, a fight breaks out in Pardis Dhyai and Tighnari ends up getting wounded from a lightning storm caused by the Balladeer. After the situation calms down, the traveler and Dehya leave to meet up with Cyno and Alhaitham. Dehya tells Cyno about Tighnari's injury, and he shows concern by asking who was behind the attack. They also relay to him the message from Tighnari.

After Nahida gets freed from the sanctuary and the face-off with the Balladeer, Cyno takes an injured traveler to Gandharva Ville. Tighnari complains about how Cyno constantly sends people to him to take care of, but he still helps out.

The traveler learns about a party that Nilou plans to host in honor of Cyno's reinstatement as General Mahamatra as well as to honor to heroes of Sumeru. They tell Tighnari about this, who responds saying Cyno had already come to visit and told him about his return to the Akademiya. Tighnari is surprised to learn about the feast, however, and says that it is possible that Cyno doesn't know about the feast. He says he won't be able to attend the party due to him being busy, but will plan to celebrate Cyno another time along with Collei.

The next time the traveler meets Cyno, they tell him that Tighnari is recovering well. He expresses his satisfaction for this, and also comments on how Tighnari has excellent medical skills. It is also revealed Cyno did indeed not know about the feast, showing that Tighnari was right.

Cyno's Story Quest
At the end of Cyno's story quest, they are shown talking together alone at Caravan Ribat. Cyno had just finished single-handedly apprehending 300 criminals, which Tighnari scolds him for. However, Cyno discusses his anger towards the criminals for the role they played in an old friend's death and Tighnari drops it, saying he understands. Tighnari then offers Cyno a trap he designed using plants, saying he can use it to aid him in battle while also help collect test data on it.

The traveler joins their conversation, and it is revealed that Tighnari had come to Caravan Ribat to find herbs for a child Cyno had met earlier in the quest and also to check for any physical injuries Cyno may have. Tighnari then mentions how lonely Cyno looks, and tells him he should relax and play some Genius Invokation TCG. He mentions that Collei is wary of Cyno due to his serious expression, which prompts Cyno to ask how the girl is doing. Tighnari responds talking about her growth and studies, and says he's tasked her with giving lectures in Sumeru City. He asks Cyno to watch over her, to which he agrees. Tighnari then leaves after telling Cyno and traveler they can find him in Avidya Forest if anything else happens.

Genius Invokation TCG
One of Cyno's favorite hobbies during his free time is playing Genius Genius Invokation TCG. It is also shown that he plays it together with Tighnari, as at the end of his profile story "Cyno's Genius Invokation TCG Deck Box" it mentions him wondering if Tighnari would be available to play at the moment. In the daily commission King of Invokations, Fukomoto tells the traveler that he was tasked with writing a book about Genius Invokation TCG and was told to use Cyno and Tighnari as inspiration for the book. It can assumed that Cyno and Tighnari are both well known for being good at the game in order for them to be considered for inspirations.

Matra's Encyclopedia of Plants
In the lore descriptions for several plant furnishing items used in the Serenitea Pot, it can be found that Cyno sought out Tighnari's help for writing on a manual guide on different plants in Sumeru. Many of these descriptions show other matra wondering who the General Mahamatra could have found who is so knowledgeable on plants, while one item called No Jumping, No Tramping mentions a matra coming to ask Cyno a question about the manual. The matra finds him having dinner with Tighnari, and Cyno promptly answers his questions with two jokes that only confuse the matra more. Tighnari jumps in before Cyno can start explaining the jokes so the conversation would end quickly, possibly because he knows that Cyno's explanations for his jokes can become very long.

Quotes
"A message for you. I brought back a specialty from the desert, two packs of honeyed dates, which helps to replenish your energy, whether in the morning or at night. Thank you for your patience in teaching and taking care of Collei. Good luck with your work and best wishes for Collei's studies."

- Cyno's letter to Tighnari

"Many researchers at the Akademiya fear that the General Mahamatra will interfere with their research. However, it seems that they are worrying about nothing. Most of them do not produce results worthy of his visit."

- Tighnari's reply to Collei asking about Cyno

"You want to see Cyno...? Well, firstly, a word of caution: if he ever comes chasing you down for work-related reasons, prepare for the nightmare of a lifetime. Other than that, General Mahamatra is a high-ranking position, so it usually isn't easy to find him. But he does occasionally go to Gandharva Ville to see Collei. As much as he might want to stay unnoticed, he can't fool my ears, heh."

- Tighnari's voiceline about Cyno: General Mahamatra

"After my adviser's rescue, I wrote him a letter to send my regards. To my surprise, he wrote back saying that someone had already given him my regards in person. He ended the letter with a query "Why is the General Mahamatra saying he wants to leverage the full might of Sumeru to restore the reputation of sages?" ...Good question. I'd like to know, too."

- Tighnari's voiceline about Cyno: Good Question

"Tighnari is different from other scholars I've met. He has the same wholehearted dedication to knowledge, but he will never cross the most important boundaries. Some scholars see themselves as gods within their own laboratories, but not Tighnari — he has always shown the same respect for every form of life. I've heard that he even declined a position in the Akademiya, and I support his decision."

- Cyno's voiceline about Tighnari: Knowledge

"Tighnari once told me not to tell jokes at the dinner table, insisting that my jokes weren't funny at all. I did not share his opinion, so I told three of my best jokes in a row, and explained the premise of each in great detail. By the time I was done talking, my food was cold."

- Cyno's voiceline about Tighnari: Jokes

"Tighnari and Collei never said it to my face, but they found Kaveh's personal anecdotes far more entertaining than the jokes I had prepared... I could see it on their faces. Hmm? What did I think about that? Well, I thought it was funny that they could laugh at such a situation."

- Cyno's voiceline about Kaveh

"I have a very close relationship with Tighnari. Given how well we know each other, I believe my message alone should be enough to bring him to our side. He knows I won't make jokes about things like this."

- Cyno to the traveler, during Through the Predawn Night

"Trust your own senses and experiences."

- Tighnari's message to Cyno, during As by a God's Side

"And Cyno, relax! You don't always have to look so serious, you know. Why don't you play more Genius Invokation TCG? Collei has always been a little wary of you, and your stern expression certainly isn't helping."

- Tighnari's to Cyno, during All Returns to Silence

Fanon
Cynonari is both Cyno's and Tighnari's most written for ship on Archive of Our Own, with 700+ works between slash and gen works.

The ship rose in popularity upon Tighnari's Official Character introduction, where a quote from a letter Cyno sent to Tighnari was used. Cyno thanked Tighnari for taking care of Collei, and he left a pack of honeyed dates for him. This led to people shipping the two of them together due to them appearing to be close friends and having close relations to Collei, who they both care for. Many people see Cyno and Tighnari as father figures for the girl, and headcanon them as a family.

Many fans find the relationship between Cyno and Tighnari to be very wholesome, as they are often shown to care for and trust one another. Tighnari, who is said to rarely leave Avidya Forest, traveled all the way to Caravan Ribat to lend his aid to Cyno at the end of his story quest. Cyno also regularly visits Gandharva Ville despite living in Sumeru City, just to visit Tighnari and Collei and have dinner with them. Fans also hypothesize that the matra mentioned in Tighnari's profile voiceline talking about Karkata is Cyno. Research on mechanical lifeforms is prohibited by the Akademiya, but Cyno has trust in Tighnari and very likely would have faith in Tighnari claiming he only intends on using Karkata as a research assistant and would do no studies on the robot itself. Cyno is someone with a great sense of judgement and shows little to no mercy for those who break the rules, so his complete faith in Tighnari's actions and decisions shows how big of an impression he has made on the Mahamatra.

Many fanworks depict Cyno as more relaxed around Tighnari due to their close friendship and Cyno letting down his guard around him. Cyno often tells jokes, which annoys Tighnari who does not find them funny. They are portrayed as partners who care deeply for one another, offering aid when possible.

Trivia

 * In Cyno's web event, Trial of the Scorching Sands, one of the items you can pack in Cyno's bag are Candied Ajilenakh Nuts. The description of the item mentions bringing some for Tighnari and Collei.
 * Both Cyno and Tighnari had a quote for each other used in their official introductions.
 * Both Cyno and Tighnari have two quotes for each other in their character profiles, something that is not very common.
 * Many fans have noted how Cyno's voice becomes much softer when talking about Tighnari. Cyno's English voice actor confirmed he intentionally softened his voice while talking about Tighnari in Cyno's "About Tighnari: Knowledge" voiceline.
 * They often eat dinner together, with Cyno traveling to Gandharva Ville to spend time with Tighnari.
 * They both appear in Nahida's character teaser as the Knight of Flowers' retainers.
 * Both of their designs have canine-like elements. Tighnari has the ears and tail of a fennec fox due to him being a hybrid, while Cyno wears a hat based on the god Anubis who has the head of a jackal.
 * Both jackals and fennec foxes are monogamous animals.
 * In Tighnari's Interesting Things voiceline, he mentions some plants using honey to lure their prey and then how it feels like he's not talking about plants anymore. This combined with the fact that jackals prey on fennec foxes and Cyno gifts Tighnari honeyed dates may allude to the idea of Cyno luring Tighnari in with honey.
 * Their normal attack strings are very similar, despite them using different weapons. They both have four attacks, with a double-hit on the third attack. They also rotate their bodies in a similar manner.
