Akian

Akian is the het ship between Akito Shinonome and An Shiraishi from the Project SEKAI fandom.

Canon
Akito and An are part of the street music group Vivid BAD SQUAD. They were previously competing as two groups. They went to the same middle school and currently go to the same high school, Kamiyama High. They're rivals and often bicker with each other about who's the best between the two, and sometimes An stops Akito from teasing Kohane too much. The two of them became immersed in music after witnessing An's father and his group RADders host and perform at the legendary event called RAD WEEKEND, in hopes of pulling off a performance that is equally hype and "in order to surpass that night."

In Vivid BAD SQUAD's Main Story, Akito was immediately interested in asking An to become part of his and Touya's street music unit after being recommended. Having seen her perform at her father's café and considering her to be of equal skill and drive. However, upon asking her to join, he was disappointed. An had rejected his offer in favor of partnering with Kohane, who she had met a few days prior. Akito felt that An's belief in Kohane would only drag her down due to Kohane's lack of musical experience not matching An's talents, leading him to instead decide to compete against her with Touya.

During An and Kohane's (now performing under the name Vivids) first live show, a friend of Akito's deliberately cut off the audio track during their performance. This caused Kohane to get struck with stage fright and forcing An to cover for her. Despite knowing that he didn't do it, Akito took the blame for the incident. He cited that he believed that he and Touya took their music more seriously than An and pointing to Kohane as evidence for it. Kohane, feeling she let An down, runs off. With An angrily telling Akito that "she expected better of him, and that she was proven wrong".

Later, after winning back Kohane (who has now decided to sincerely adopt An's dream of wanting to surpass RAD WEEKEND), the girls are approached by Akito's friend, who clarifies that Akito wasn't the one who sabotaged their concert and apologized. Realizing her mistake, An and Kohane band together to make up with Akito and check on him after his fight with Touya.

It is shown that Akito is one of the first people to usually notice and point it out when something is wrong with An or she is feeling doubtful. In Chapter 1 of the Singing in Sync event, Akito instantly asks why An told Kohane that she'll cover for her in the unlikely event that anything goes wrong during their battle event at STAY GOLD. An doesn't understand what Akito means by it and he decides not to bug An more despite his suspicions. In Chapter 3, after Kohane runs out and An laments the fact she failed her and couldn't protect her, Akito immediately calls her out on this, making her realize she doesn't consider Kohane her equal. When Akito then says they need to discuss and make sure they won't fail the same way, he specficailly asks An if she was listening. At the end of the event, An then thanks Akito for making her open her eyes to her conflict.

This later happens again in the Bout for Beside You event, where he and Miku help An realize she is afraid that Kohane will eventually overcome her in singing and leave her behind.

In An's Colorful Festival card, where she goes into a SEKAI of the Vivid Street in her memories, she mentions to Len and Rin that Akito inspired her and how he also kept telling her they'll make their dream of surpassing RAD WEEKEND come true one day.

Fanon
Akian is one of the most popular het ships in the Project SEKAI fandom with its popularity being primarily owed to the fact that the two are in a co-ed unit together, something rare in and of itself due to the games distinct lack of male characters in units compared to the vast number of female ones. Because they're in the same unit, they have more interactions with each other along with their fellow unit members than they do with any of the characters outside of their group. Because of these common interactions, it is seen as somewhat of a rival to both Anhane and AkiToya. It is often shipped together with Toukoha.

For fan reactions, Akian fans tend to see Akito and An's dynamic within their unit's main story and additional materials as entertaining in their rivalry, and their similar passion towards their goals. It also helps that in their pairing you can find some pretty famous romantic tropes like "tsundere" or "like an old married couple". In the Eastern part of the fandom, one of the most popular prompts is to make Akito flustered by An's "too close" sense of distance. At the same time, fans of other ships often criticize Akian, accusing its of being less interesting than the slash ships with Akito and An, not least because of the friendship theme and lack of too explicit ship bait, slash pairings seem to get more development and attention from the author than straight. But one way or another, in the end it often comes down to choosing ships from the het and slash options in general. It is both An and Akito's 2nd most written ship on AO3. In Pixiv, they have 948 works in total (238 illustrations + 88 manga + 622 fanfictions), making them the 3rd het ship with most fan content in the branch after Ruinene and Emukasa.
