Elm is a member of the Ace Operatives the most elite group of Huntsmen and Huntresses from Atlas Academy. Their leader is Clover Ebi. Later, Elm deflects that she and her team are friends, claiming that her job "isn't the schoolyard", in agreement with Harriet Bree's assessment that the Ace-Ops' relationship is purely based on work.
By the time of "The Final Word" however, she proves this statement wrong by calling Harriet her friend when she tries to reason with her not to bomb Mantle.
Elm, along with the other Ace-Ops, were called into Mantle because of reports of a stolen Atlesian airship entering its airspace and because of the unauthorized use of weapons by civilians. The culprits were Team RWBY, Jaune Arc, Nora Valkyrie, Lie Ren, Qrow Branwen and Oscar Pine, who defended the city from a pack of Sabyrs. Elm and her team caught the group by surprise and seized their weapons before leaving them in the custody of the authorities.
Following the miscommunication, Elm was quick to express an overzealous apology and make amends with the team. Later, Elm deflects that she and her team are friends, claiming that her job "isn't the schoolyard", in agreement with Harriet's assessment that the Ace-Ops' relationship is purely based on work.
Later, upon Blake and Yang's treachery being revealed, the truths Ruby held back revealed, the looming assault of Salem, and Team RWBY's stance against General Ironwood's pragmatic approach to abandon Mantle to save who they can instead of holding their ground, she now considers the team her enemies and would now hold no reserve in using excessive force to capture them on Ironwood's orders like her fellow Ace Ops. Elm, in particular, was quite shocked and hurt by Team RWBY's apparent betrayal due to her having clearly grown fond of them during their stay in Atlas.
Clover was Elm's leader. In "As Above, So Below", Elm and Clover shared a friendly handshake before entering combat.
After his death, Elm could be seen silently grieving for him after being shown his body in "Divide".
Vine was Elm's teammate. She and Vine had a casual relationship and they got along very well. In "With Friends Like These", Vine served as a voice of reason when he and Elm fought Yang Xiao Long and Blake Belladonna, offering the Huntresses to stop the fight peacefully. Elm was angered at this, telling him she wants them to pay for betraying their trust. Elm later told him to stop "going easy on them", which Vine saw as Elm's attempt to convince herself of what she's saying.
Their relationship started to strain in "Ultimatum" when Vine attempted to comfort Elm but she brushed his attempt off with annoyance.
By the time of "The Final Word" however, their relationship is repaired when they both work together to stop Harriet from bombing Mantle. After they succeed and the bomb is armed, Vine decided to sacrifice his life to save his friends. Before he did so, Vine and Elm shared one last look with each other before she was forced to watch him die. She was devastated by Vine's death, mourning him not long after.
Harriet and Elm tend to find each other in agreement. They are both shown to pick fun of Marrow, laughing along together. However, she agrees with Harriet's assessment that their team aren't friends. Nevertheless, she gets along well with all members of her team.
Their relationship was temporarily strained when Harriet attempted to bomb Mantle herself in "Worthy", but was later mended in "The Final Word" when she called Harriet her friend and convinced her to stop with her plans. This shows that she really does consider Harriet her friend, proving Harriet's previous statement about them being just co-workers wrong.
Marrow is Elm's teammate. She is often seen poking fun at him, believing him to have a loud mouth. In "Pomp and Circumstance", she playfully pushes him to the ground when celebrating Team RWBY and Team JNPR for their promotion to being licensed Huntsmen.
Their relationship was later strained in "Risk" when Marrow refused to help Ironwood bomb Mantle and he asked the other Ace-Ops if they even think for themselves. Later in "Creation", Marrow restrained the other Ace-Ops using his Semblance.
By the time of "The Final Word" however, their relationship has seemingly mended after she stopped assisting Ironwood with his plans and they watch the destruction of Atlas together.
Ironwood was known to have acknowledged Elm's abilities and talents as a Huntress as being one of the best Atlas had to offer and recruited her for the Ace-Ops. Later Ironwood would reveal the truth about Salem to her and bring her into the fold about Ozpin's shadow war against her, showing his trust in her.
Elm in return had a strong sense of loyalty and faith in him and followed his orders without question. This is seen where she agreed with his plan to abandon Mantle despite the fact that the evacuations were not yet completed. Later Elm was seen to show hostility and later complete rage against Team RWBY upon learning of their "treachery" and compiled with Ironwood's orders to arrest them.
In "Divide", Elm was shocked when Ironwood shoots Councilman Sleet, yet she continued to serve him as he continued to make more and more extreme decisions that she herself became unsettled with, but she insisted that there was no other way. In "The Final Word", she decides to stop listening to his orders and follow her own decisions, as shown when she calls Harriet her friend and demands she stop trying to bomb Mantle.
Elm respects Winter as a fellow Special Operative under Ironwood and has a degree of comradery with her.
In "Strings", Elm is angry on Winter's behalf due to Penny claiming the Winter Maiden's powers and holds her responsible for her injuries and the loss of Winter's chance at becoming the Maiden.
Elm, along with the other Ace-Ops, were called into Mantle where they arrested Ruby and her team along with Jaune, Nora, Ren, Qrow and Oscar, who defended the city from a pack of Sabyrs.
Following the miscommunication, Elm was quick to express an overzealous apology and shook Ruby's hand so hard that she flopped around like a rag-doll, and left in a daze as she rose to her feet.
Later, after a successful mission where they defeated a Geist Grimm in an abandoned Dust mine, Elm celebrates by hoisting a joyous Ruby onto her shoulder, parading her around as she chants "We win, we win, we win, we win!"
When Ruby questioned Harriet on whether the Ace-Ops were friends, Elm agreed with her teammate in that they aren't friends, claiming that their work isn't "a schoolyard."
Elm, along with the other Ace-Ops, were called into Mantle because of reports of a stolen Atlesian airship entering its airspace and because of the unauthorized use of weapons by civilians. The culprits were Blake and her group, who defended the city from a pack of Sabyrs. Elm and her team caught Blake and the others by surprise and seized their weapons before leaving them in the custody of the authorities.
In "Gravity", Elm felt deeply betrayed by Blake when she learned that she and Yang purposefully let Robyn Hill escape during their mission to capture her, leaked information about Amity Communications Tower to her and kept vital information about Salem from her and Ironwood.
During "With Friends Like These", Elm engaged her and Yang in battle in order to actively vent her anger at them by channeling it into their fight. Blake attempted to convince Elm and Vine not to abandon Mantle. However this plea fell on deaf ears. Later after Yang insulted Elm and the rest of the Ace-Ops by stating that they were "just following orders", Elm violently threw Blake towards a wall in anger before attacking Yang.
Elm, along with the other Ace-Ops, were called into Mantle because of reports of a stolen Atlesian airship entering its airspace and because of the unauthorized use of weapons by civilians. The culprits were Yang and her group, who defended the city from a pack of Sabyrs. Elm and her team caught the brawler and the others by surprise and seized their weapons before leaving them in the custody of the authorities.
During their time working together with Yang and her team, Elm had grown close to and genuinely trusted Yang. She later felt betrayed when she learned that she and Blake had purposefully let Robyn Hill escape, leaked information about the Communication's Tower to her and kept vital information about Salem from her and the General.
In "With Friends Like These", Elm was angered and frustrated with Yang and Blake due to their betrayal of her trust and channeled it into her fight with them. Later when Yang taunted her about her simply "following orders", Elm was enraged by her insult and violently attacked her.
In "War", when Yang had been taken into custody along with Jaune and Ren, she mocked Elm, Winter and the rest of the Ace-Ops for the fact that they were "still just following orders".
In "Pomp and Circumstance", Nora showed an immense interest in Elm; asking her if she wanted her to become her new best friend. The hyperactive girl even suggested that their pair name would be "Thunder Thighs" in a very dramatic way, while Elm could only stare at her in silent confusion.
