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 constantly, 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 also mentions that when they were younger, Ena would go as far as scratching Akito and throwing things at him.

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

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.

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. In another, Kohane runs into Akito at the shopping mall and tells her to stay quiet so he doesn't alert Ena and let her know where he is.
 * They have an upcoming cover from DECO*27, "Salamander", which was specfically created for the Nissin Cup Ramen collaboration with Project SEKAI.
 * They like and dislike the same foods (cheese cake and carrots). Mizuki also points this out in Ena's introduction video, causing her to get annoyed.
 * When not using Ena's name, Akito refers to her with the term "Aneki" (姉貴), which is most commonly translated as "Sis".
