Shinonome Siblings

Akiena is the family ship between Akito Shinonome and Ena Shinonome from the Project SEKAI fandom.

Canon
Akito and Ena are siblings with a one-year difference, with Ena being the older sister. At the beginning of the story, it is shown that the siblings do not get along as well as the other sibling pairs (Tsukasaki and Shizushiho), with Ena constantly lashing out at Akito, using him as an errand boy, and the latter calling her annoying among other things. This is also because Ena is mad at Akito for refusing to use his artistic talents, something she is envious of. At one point Akito mentions that when Ena gets mad, she at times throws things at Akito and even scratches him. Touya also mentions that he remembers how Akito's skin was filled with scratches when they met for the first time.

Outside of the area conversations, the two are shown interacting in Ena's 1* first side story.

Unsatisfied Pale Color
In Chapter 1, Ena happens to run into Akito while going to get some snacks, then asking him to get snacks for her, however he declines telling her to get it herself and leaves. In Chapter 2, Akito greets Ena as she walks into the living room guessing she pulled an all-nighter, however Ena just tells him to shut up and asks why he isn’t rushing to school and he answers her question. In Chapter 4, Akito walks into her room calling her loud, and quickly asking what’s wrong with her room, while Ena responds telling him to shut up. However, he then notices what she’s throwing out and questions her, but she says it has nothing to do with him. Despite this, he still asks and she tells him the same thing while kicking him out of her room. And lastly in the final chapter, Akito greets her once she enters the living room and Ena apologizes for lashing out on him, however he says it didn’t bother him. She then says she decided to continue drawing, and Akito tells her to do her best.

My Footprints, Your Destination
In Chapter 2, the Niigo members run into VIVID BAD SQUAD after leaving the diner.

Fanon
In the Eastern fandom, Akiena is quite popular and the most popular out of the three sibling pairs, and it is often treated as a het ship. It currently has over 600 works on Pixiv. Meanwhile in the Western fandom, its romantic following is rather minor and most people have voiced their distate and disgust for the ship and Akiena shippers as well because of its incestuous nature. Both are shown to bicker a lot, sometimes even more than in canon. After the release of both Akito's White Day 2022 costume and Ena's salamander design for Salamander, there has been a lot of fanart where Akito is a knight hunting Ena or them being in a fantasy setting together.

Trivia

 * In multiple area conversations as well as one of the 1-komas, it is shown that Ena often drags Akito along with her while going shopping and making him carry her bags.
 * In an area conversation, the two are at the music store where Ena is trying to find an album which she saw quickly in a commercial based on its cover while Akito grumbles but helps her.
