KatsuScara

KatsuScara is the slash ship between Katsuragi and Scaramouche from the Genshin Impact fandom.

Canon
Although Katsuragi and Scaramouche have never had a canon interaction, they appear to have been close friends in the past. This dates back to when Scaramouche was a traveler without a known name, referred to as a "nameless eccentric". Their story is recorded in the Rather Aged Notes found in Tatarasuna. The notes state that Katsuragi (Inspector Mikoshi Nagamasa's yoriki), had found him wandering on Nazuchi Beach. He recognized the gold ornament Scaramouche brought with him as being connected with the Raiden Shogun, and warned him to never reveal his identity to others. He presumably brought him back with him to Tatarasuna, joining a group consisting of Nagamasa, Miyazaki, Nozomu, and Kinjiro. Nagamasa had an interest in weaponsmithing, and with the help of Katsuragi and Miyazaki forged a blade named the Daitatara Nagamasa. To celebrate the blade's creation, Katsuragi and Scaramouche performed a sword dance together, the dance written as a "joy" to have seen.

After finding out Scaramouche's ties to the Raiden Shogun, Nagamasa is said to have "dealt with him" in some way. The group also seemed to have searched for Scaramouche, who had gone missing, to no avail. Nagamasa learns of Katsuragi's "misconduct", and in a rage, executes him with the Daitatara Nagamasa. The blade would come to be known as the Katsuragikiri Nagamasa, (Katsuragi-slasher Nagamasa).

Later, Scaramouche, taking the name Kunikuzushi, swore revenge against "the bladesmith", masterminding the fall of the Raiden Gokaden, five Inazuman weaponsmithing schools. After reaching the Isshin line and encountering Kaedehara Yoshinori, however, he claims to have lost interest in the project, leaving the fifth school untouched, surviving to the present era.

Fanon
Even though they both were close in canon, KatsuScara is considered a rare-pair. People who do ship it have their own set of headcanons, and those who don't see them having a platonic relationship, with Katsuragi as a friend or father figure to Scaramouche.

It is theorized that the reason Scaramouche abandoned his revenge plot is because he thought that he was harming Katsuragi’s descendants. In the 2.6. event, Hues of the Violet Garden, it has been proven that the reason behind the collapse of Kaedehara Kazuha’s clan is because they were one of the main families of the Isshin Art, which had collapsed as a result of Scaramouche's machinations. Scaramouche encountered Kazuha's ancestor, Kaedehara Yoshinori, when he had come with a group to investigate the Isshin school's failed forgings. After defeating the group, Scaramouche seemed to have recognized something about Yoshinori, and sternly asked of his relation to the name “Niwa”. Niwa was revealed to have been Yoshinori's surname before his father disappeared and Yoshinori was adopted into the Kaedehara clan. After learning this, Scaramouche then left him alone. It is believed that Niwa is Katsuragi’s surname.
