Kaeya │ overprotective "friend"

Kaeya is the Cavalry Captain of the Knights of Favonius. He is held in high regard by the people of Mondstadt — even with all his eccentricities and secrets.

Personality: Kaeya is an outwardly confident and charming individual with a flair for drama. He is sometimes seen as overly laid-back and even lazy, but he takes his work seriously. He is surprisingly popular among the elderly of Mondstadt, even earning himself the title of "top candidate for grandson-in-law." His charisma and determination have earned him the admiration, respect, and favor of many people in Mondstadt — yet, his love for provoking others has also gained him the exasperation of those same people. Kaeya also enjoys putting people into high-stress situations and challenging their values, which he does to both his enemies and his allies alike. He takes pleasure in seeing the hesitation in his comrades' eyes at the moment just before they dive into battle with him, just as he takes pleasure in the look of fear in his enemies' eyes as they face off against him.

He seems to get a kick out of telling bold-faced lies and convincing others to do his work, but this serves him well in his role in the Knights of Favonius. He is a self-proclaimed "anti-hero with an attitude problem;"[2] as long as everything ends the way he wants, Kaeya does not care about the methods used. Still, according to his informant Vile, he draws the line at working with those who threaten other people's families, believing they deserve to be "hunted down and destroyed."

Despite his extroversion, the Traveler has observed that he appears to struggle with loneliness, though he playfully deflects when confronted about it.[3] He frequently reminds the Traveler that they can talk to him, invites them to spend time with him, insistently offers (sometimes extensive) assistance, and often voices his disappointment whenever the Traveler has to leave, showing his desire to be helpful and aversion to being alone.

Appearance: Kaeya uses the tall male model. He has a tanned complexion and navy-blue hair with streaks of lighter blue, accompanied by a waist-length lock of hair that begins at the base of his scalp on the back of his head at the left. His visible eye is periwinkle with a diamond-shaped pupil that is shared with other characters known to be from Khaenri'ah. Over his right eye, he wears a gold-trimmed black eyepatch that is mostly covered by his bangs. Kaeya has not been seen without his eyepatch, but his right eye, which is functional, is implied to have a scar over it due to being wounded by Diluc during their battle after Crepus' death.[4][5]

Notably, while other Mondstadt characters' Vision casings feature three feathers per wing, Kaeya's Vision on his default outfit only features two feathers. He is also the only one with a wing on the right side of the back of his Vision (other Mondstadt Visions have them on the left side or no wings at all on the back). Kaeya is one of only two characters across all nations who has a Vision with clearly nonstandard casing, with the other character being Furina.

Character Details/Backstory: Kaeya Alberich is an adopted son to the Ragnvindr Family, the renowned wine tycoon.

It has been a long time since he last called Diluc Ragnvindr "brother."

Kaeya currently serves as the Cavalry Captain of the Knights of Favonius, and is trusted by Jean.

Kaeya is often the one wrapping things up in every incident that occurs in Mondstadt's vicinity.

It is a curious fact that your best chance of finding Kaeya is not by visiting the Knights' headquarters, but by frequenting the taverns at night.

Kaeya is often found sitting at the bar, gossiping with the city folk, and sipping the famed Mondstadt beverage, Death After Noon.

He is surprisingly popular among the elderly of Mondstadt, even earning himself the title of "top candidate for grandson-in-law."

It's hard to imagine someone as mischievous, amiable, and wine-loving as Kaeya being the Cavalry Captain of the Knights of Favonius.

Hunters and bandits alike are often among Kaeya's drinking buddies. As wary of him as they may initially be, all are ultimately disarmed by his smooth talking, and end up telling him everything he wants to know.

Depending on what they then make privy to Kaeya, their night may turn into an uncontrollable nightmare or remain one of harmless banter.

"Everyone's got a secret, but not everyone knows what to do with it."

Says Kaeya, with his usual arrogant smirk.

"Justice is not an absolute principle, but is the result of striking that fine balance between strength and strategy. As for the details of how it's done... Don't worry yourself too much about that."

Kaeya once said these words in front of Grand Master Varka.

As long as everything falls into place the way he expects in the end, Kaeya doesn't care all that much about how it's done.

This cavalier attitude is what defines his character.

Not that different from Death After Noon's wild and explosive taste, one might add.

However, his reckless approach to things is not uncontroversial.

Once, in order to force a bandit leader into facing him directly, Kaeya triggered the Ruin Guard at an ancient ruin to cut his opponent off, putting his own men at risk in the process.

It's times like these when even Jean, who puts a lot of trust in Kaeya, finds herself shaking her head in disapproval.

Not that this bothers Kaeya, of course. On the contrary, he actually enjoys putting people into the difficult position of making tough decisions.

He takes pleasure in seeing the hesitation in his comrades' eyes in the moment just before they dive into battle with him, just as he takes pleasure in the look of fear in his enemies' eyes as they face off against him.

The flourishing winery business in Mondstadt has been a great source of prosperity in the region over the years. This prosperity often entices greedy bandits and monsters to the area.

They are a motley bunch who hide in the shadows, and their backgrounds, motives, and allegiances are varied and complex.

Kaeya battles against this threat to Mondstadt not only with his sword, but also with his smarts and his wit.

A young knight once dedicated years of his life to studying threats in and around Mondstadt, and reached an astounding conclusion:

When Death After Noon is out of season due to lack of supply, the number of reported incidents inside and outside the city show a drastic decrease, and this remains the case until Death After Noon returns to the market...

The young knight showed his findings to Cavalry Captain Kaeya in hopes of getting some advice from him.

"Interesting. I'll look into it." Kaeya answered, with a wry smirk on his face.

Generally speaking, Kaeya is an easy person to have a conversation with. The only topic that you will never hear him discuss is his past.

Even when the Grand Master demanded information on his background, Kaeya skirted around the issue and gave only vague answers devoid of details.

"One afternoon near the end of summer a decade ago, my father and I passed by the Dawn Winery."

"'I'll go get us some grape juice for the road,' he said, but he never came back."

"If Master Crepus hadn't taken me in, I doubt I'd have made it through the storm that night."

This matter-of-fact description hides a carefully constructed lie.

Kaeya has never once spoken the truth about what happened that afternoon:

"This is your chance. You are our last hope."

Kaeya's father squeezed his son's lean shoulders as he spoke, seemingly looking right through Kaeya to some place far beyond.

On the other side of the horizon sat their distant homeland of Khaenri'ah.

Kaeya would never forget the look of both hope and hatred in his father's eyes as he uttered those words.

Many citizens still remember the two most eye-catching young gentlemen in all of Mondstadt a few years ago.

One of them was the dapper Diluc, an elegant swordsman who always had a warm smile and a confident posture.

The other was the eccentric Kaeya. He was Diluc's friend, supporter, and sounding board, ensuring he got through every challenge he faced smoothly.

They were almost like twins, knowing each other's thoughts and intentions without a word, protecting Mondstadt in both light and dark.

...Until that fateful day, now ingrained deep in Kaeya's memory, when the convoy that Diluc was escorting was attacked by a huge monster.

It was the first and only time that Kaeya failed in his duty.

By the time Kaeya finally reached Diluc, it was all over.

The power their father had used to successfully fend off the attack backfired, taking their father's life.

Both Kaeya and Diluc were shocked by what they had witnessed, losing the calm composure a knight should retain.

"Even someone like Master Crepus would submit to such a dangerous and evil power..."

Sinister thoughts flashed through Kaeya's mind, and he simply smirked:

"This world is truly... fascinating."

All while their father lay dead in a pool of his own blood. It was on that night that the two sons' paths diverged.
