Elrena is a Dandelion and a Keyblade wielder belonging to the same Union as Strelitzia in Kingdom Hearts Union χ. She is the human form of Larxene.

Story

Before Kingdom Hearts Union χ

Sometime prior to the Keyblade War, Elrena is chosen by the Keyblade and joins one of the five Unions in Daybreak Town, where she is given a Chirithy. On occasion, Elrena comes into contact with her fellow Union member, Strelitzia. Eventually, Ava invites Elrena to join the Dandelions, which Elrena accepts.

When the time comes, Elrena leaves the old world behind and journeys to the new world, subsequently forgetting everything about the world she had left behind. Elrena then relives her past experiences alongside the other Dandelions, although unaware of the tragedy of the Keyblade War.

Kingdom Hearts Union χ

Lauriam asks Elrena about Strelitzia.

Lauriam, Strelitzia's older brother, is unable to find her after the Keyblade War, and begins searching for her. Having heard Elrena's name from Strelitzia, Lauriam seeks Elrena out to ask about Strelitzia. Although Elrena admits to having known Strelitzia, she is unable to offer any valuable information herself. Recalling that her Chirithy was friends with Strelitzia's own Chirithy, Elrena summons it. After her Chirithy reveals a connection between Strelitzia's last known whereabouts and Skuld, Elrena and Lauriam part ways, with her opting to investigate Strelitzia's disappearance on her own.

Elrena sees a glitch of Strelitzia.

Elrena and her Chirithy enter the building where Strelitzia was last seen, and find it empty. Just as they are about to leave, they witness a projection of Strelitzia's final moments. Elrena and her Chirithy try to trigger the projection again, but to no avail. Elrena contacts Lauriam again to report her findings. He thanks her for her help, but when she tells him what she and her Chirithy had seen, he bursts into the vacant house calling Strelitzia's name, but is also unable to re-trigger the glitch. Elrena's Chirithy then adds that it remembers Strelitzia's Chirithy saying that Strelitzia wanted to induct Player into the Dandelions in order to save them from the imminent Keyblade War. This reminds Elrena of Ava's speech to the Dandelions, and she notes that this is odd considering that, from her perspective, the Keyblade War never ended up happening.

Later, Elrena comes to the clocktower to tell Lauriam that she has new information about Strelitzia. Elrena's Chirithy claims to have seen someone that looked like Strelitzia headed toward town alongside someone in a black coat. Elrena accompanies the Union leaders and Player to the clocktower's basement, where they discuss what to do with the lifeboats that can take them out of Daybreak Town, as the data world is beginning to deteriorate. Elrena expresses that she doesn't believe she deserves to take a spot in one of the lifeboats because she isn't a Union leader, but Lauriam tells her that she gave him hope for finding Strelitzia and urges her to help him find her, to which she agrees. Elrena takes a lifeboat alongside Lauriam, Ventus, and Brain to return to the real world.

Elrena appears to be alone after escaping Daybreak Town in the lifeboat.

Back in the real world, Brain tells Lauriam and Elrena to each take a lifeboat alongside Ventus and escape from the collapsing Daybreak Town. Elrena waves to Brain before the lifeboat closes and the tower shakes with a strong tremor as the three lifeboats are launched. Elrena is later seen lying unconscious on a desolate and stormy cliff in Enchanted Dominion.

Between Kingdom Hearts Union χ and Kingdom Hearts Chain of Memories

At some point, Elrena was found by an unknown member of Organization XIII and joined them as their twelfth member. Elrena's heart was separated from her body, and her strong heart allowed her to continue on as her Nobody, Larxene.

Between Kingdom Hearts Chain of Memories and Kingdom Hearts 3D: Dream Drop Distance

With the destruction of her Heartless and Nobody, Elrena is revived, but is approached again to become a Nobody to host a fragment of Master Xehanort's heart to become a member of the real Organization XIII.

Design

Elrena has aquamarine eyes and neck-length blonde hair with shorter sideswept bangs, and two distinct upward-pointing strands which curve back and resemble antennae. Her attire resembles a school uniform; she wears a turquoise leather jacket over a white collared shirt, loose black necktie, black silver-buckled belt, and wide black leather shorts. She has a silver chain hanging from her jacket and a similar chain necklace. She wears knee-high black socks and turquoise leather boots.

Personality

Elrena is helpful and supportive as she tried to help Lauriam solve the mystery of his sister's disappearance. She is shown to be deeply touched by Lauriam's devotion to his sister, and that Strelitzia had thought highly of her. Her Chirithy notes that she usually does not concern herself with other people's business, suggesting that Elrena is not a very social person.
