Rannett

Rannett is the slash ship between Razor and Bennett from the Genshin Impact fandom.

Canon
They have not interacted in the story mode as of present, but are both a part of the Adventurers' Guild located in Mondstadt. Currently considered a rare pair as the two don't have any in-game scenes together, and aren't well known in the fandom either. Their voicelines reveal that they do know each other, and sometimes hang out:

Bennett's voiceline states that he refers to Razor as, "Wolvendom guy" and that he sees him as, "kinda feral." He continues to say that although [Razor] doesn't talk much, he's alright. Additionally, Bennett sometimes cook meat for him, and in exchange Razor teaches him how wolves communicate.

Razor's voiceline reveals that he thinks Bennett talks too much and whenever they eat together, he's never full.

Genshin Impact isn't a game that focuses, or seems to care much, on romantic plots seeing as they don't have any canon crushes/love interests currently and probably won't. As like many other GI ships, Rannett is based off their voicelines and seeing how they interact with each other with no in-game cutscenes.

Rannett share many similarities such as their scars, love for meat, and being orphaned as a baby, with a strong, caring personality towards their friends and family. While Bennett is very outgoing, his bad luck often drives people away; Razor, on the other hand, simply isn't a fan of human interaction, so, in a way, they also share that quality.

In-game, they are a good combo as with Bennett's ult, Razor attack dmg increases and applies Overloaded to the enemy - though Bennett is technically compatible with most, if not all, of the other playable characters. They are often seen in teams together because they're both easily obtainable as four star characters and do their roles very effectively.

Quotes
"Wolvendom guy! Looks a little on the feral side... doesn't talk much... but he's alright! We both love eating meat, so we got that in common. I sometimes cook some meat for him, and he teaches me how wolves communicate in return. Haha! You should join us next time!" - Bennett's voiceline about Razor

"Bennett... Much talking. Eat with him, never full." - Razor's voiceline about Bennett

Fanon
Rannett began mostly with random headcanons and thoughts that the two would be cute together. As stated in the "Canon" section, they share many similarities and are friends. Razor, with his natural survival skills, would not have as a hard time with Bennett's bad luck, as say, anyone else. Their relationship is an "opposites attract" type, as their personalities heavily contrast. While Bennett is energetic and optimistic, Razor is more faint and prefers not to talk, that being said, they are both very kind and are shown to greatly treasure close bonds.

They are also the same age (16) so this shows no complications age-wise, and can further be optimized in fandom headcanons such as Highschool/Modern AUs or simply them sharing the struggles of being teenagers.

If not as lovers, they are popularly depicted as close friends, along with a similar ship, Xingyun.

In fanfiction, Razor is depicted as honest and forward about his feelings, most times not even understanding them as he has very few knowledge about humans himself. Bennett is written as a bubbly character, sometimes breaking and revealing just how lonely he is sometimes, and with Razor's inability to comprehend whether he is a human or wolf, they comfort each other. They are showcased as a fluffy couple.
