Kazukoko

Kazukoko is the het ship between Kaedehara Kazuha and Sangonomiya Kokomi from the Genshin Impact fandom.

Canon
Kazuha and Kokomi are both from Inazuma, and they know each other since Kazuha was formerly affiliated with the Watatsumi Army, an organization led by Kokomi. The two are both five stars, but they use different weapons and elements. Kazuha is an Anemo sword user while Kokomi is a Hydro catalyst user. The two are direct opposites when it comes to traveling. Kazuha is a traveling wanderer while Kokomi is a hibernating homebody.

In Kazuha's voiceline for Kokomi, he mentions that there was no one who wouldn't look up to Kokomi during his time with the Resistance. He refers to Kokomi as "Her Excellency" as many other people do. Kazuha is able to notice that Kokomi isn't focused on winning at all costs, and Kokomi would always try to minimize casualties while planning her next move. Kazuha says that it also seems that Kokomi is trying to take charge of both internal and foreign affairs for Watatsumi Island. Kazuha questions if that would be too much to expect of Kokomi.

In Kokomi's voiceline for Kazuha, she recalls when Kazuha bunked with the Resistance. She remembers him getting along with and fighting alongside Gorou. Kokomi talks about how carefree Kazuha is and how he doesn't like constraints. Kokomi says he would closely comply with every command when he was among the Resistance. Kokomi views Kazuha as an outstanding swordsman as well as a very refined character.

During the fight between the Resistance and the Shogun's Army, Kazuha comments "Heh, calm as the breeze, my lady" after Kokomi arrives and leads the Resistance. Afterward, Kokomi welcomes Kazuha back to their group.

Quotes
"​​During my time with the Resistance, there was no one among our ranks who wouldn't look up to Her Excellency. As someone with a great passion for military matters, victory at all costs isn't really part of her ethos. She'd always try to limit the casualties to the minimum while planning her next move. By some accounts, it also seems that she seeks to take charge of both internal and foreign affairs for Watatsumi Island. Wouldn't that be too much to expect of herself though?"

- Kazuha about Kokomi

"Kazuha once came and bunked with the resistance for a time. If I'm not mistaken, he got along very well with Gorou — they would often fight side-by-side in battle. Kazuha has a carefree personality and doesn't like constraints, but he would follow every command to the letter when he was among our ranks. In my opinion, not only is he an outstanding swordsman, but a very refined character."

Fanon
Kazukoko isn't the most popular ship, though it has plenty of fans and fanart. The ship is rivaled by KazuScara and KazuGorou on Kazuha's side and KokoSara and Kokorou on Kokomi's side. Since Kazuha and Kokomi are both shipped with Gorou, some people like to ship all three characters in one ship, Kokorou. Gorousara is also sometimes paired alongside Kazukoko. There's a decent amount of fanfiction for Kazuha and Kokomi, with there being 40+ romantic works and 32+ gen works for the pairing.
