Ephemer from Kingdom Hearts χ
Ephemer/a (voiced in Japanese by Yūto Uemura and in English by Michael Johnston) is one of the characters that we first meet in Kingdom Hearts χ/Kingdom Hearts Unchained χ.
Like everything in Kingdom Hearts, there are many varied layers to his character and the story surrounding him, but we mostly see him in context with the Foretellers and Dandelions, such as the Player character, and Ventus.
Ephemer has short grey hair with a light curl to it (the wig I linked is actually the one I personally used for my cosplay for him!), and bluey-teal eyes. Like his backstory, his outfit is also layered.
He wears a simple short-sleeved button up white shirt with a short-sleeved black bolero jacket over top, finished off with a tasseled and detailed red scarf. Around his waist he wears a tan colored belted satchel, brown baggy cargo pants, and rounds it all off with flared wrist black gloves and matching high black boots.
Elrena from Kingdom Hearts Union χ
Elrena is a member of the Dandelions, a group of keyblade wielders in the Kingdom Hearts mobile game Union χ, and the Somebody of Larxene, a member of Organization XIII.
As a member of the Dandelions she is also friends and commonly teamed up with Strelitzia, who is Lauriam‘s little sister, Lauriam later becoming Marluxia in the Organization as well.
While the two little antenna points in her hair stays consistent from being Elrena to becoming Larxene, her younger form does have bangs as well. Her eye color being a tealy green does however stay the same (up to a point).
Elrena wears a white buttoned shirt over a silver beaded necklace, with a black tie over top, a matching black belt with silver buckle and black athletic shorts, a pocket chain to match the necklace, a teal biker jacket, black knee high socks, and zip up boots that match the jacket.
Lauriam from Kingdom Hearts Union χ
Lauriam is one of the members of the Dandelions in the mobile game Kingdom Hearts Union χ and was chosen to be one of the new union leaders, he later on becomes Marluxia in Organization XIII.
The majority of the time we see him, he is looking to find answers about what befell his sister Strelitzia, and her teammate, Elrena, finally gives him a concrete answer, which sends him into a spiral.
Lauriam looks very much the same as he does later on when he becomes Marluxia, though his dusty pink hair is a little shorter and choppier here, but his eyes are still the same vibrant blue.
He wears a longer white button shirt with flared sleeves and a stiff flared collar, a black, gold buttoned, vest with tattered ends that reach down to the backs of his legs, deep pink pants tucked into his boots, and black front zip boots with gold detailing.
Kairi
In the beloved Kingdom Hearts series, Kairi is the childhood friend of both Sora and Riku, and is the love interest of Sora. Throughout the first game, Sora and Riku are set on different paths trying to find a way to save her. Later in the game, it is revealed that she is one of the Seven Princesses of Heart, and restores Sora’s form after he is transformed into a Heartless.
