Loona/History

Past
Not much is known about Loona's history, but at some point before the start of the series, Loona was given up for adoption at a Hellhound Adoption Foundation, where she lived like a prisoner and gave the employees a hard time until Blitzo adopted her when she was one month away from turning eighteen. Despite being old enough to look after herself, Blitzo used to hire babysitters to look after Loona during his absence but the babysitter apparently didn't like Loona.

When Blitzo opened I.M.P, he hired Loona as the receptionist; due to her laid back and dismissive nature, it is presumed that Loona did not actively seek out the position and only took it due to Blitzo asking her to since he didn't want her in the field out of fear that she may be hurt or worse, despite the fact that Loona is just as good, if not better, in both using guns and fighting bare-handed.

"Loo Loo Land"
Loona gets annoyed when Millie, Moxxie and Blitzo get excited about going to Loo Loo Land and shouts at them to "Shut the fuck up!".

"Spring Broken"
Loona apparently struggled with making friends, as she outright confesses this to Vortex as a poor attempt to flirt with him, and reveals that she had no friends at all until he offered to invite her to his girlfriend's parties to help her make friends.

"The Harvest Moon Festival"
Loona goes with I.M.P to the Wrath Ring for the Harvest Moon Festival. When Millie introduces Loona to her parents as Blitzo's hellhound Loona declines giving them her name, saying they don't deserve to know it. She then videos Moxxie struggling to kill the hell hog.

Later, outside, whilst using her phone Loona hears Blitzo whistle out to her while he and Moxxie fight against Striker. Loona arrives just as Blitzo and Moxxie had Striker cornered and kicked door the bedroom open, slamming it into Moxxie, and accidentally giving Striker the opportunity to escape.

"Truth Seekers"
After Blitzo and Moxxie are captured by D.H.O.R.K.S., Loona and Millie return to the human world and sneak into the D.H.O.R.K.S. Facility to rescue them. After some time in the building the four demons find each other, but are surrounded by numerous D.H.O.R.K.S. agents, causing Loona and the other I.M.P members to slaughter almost every agent inside.

"Ozzie's"
Loona sat at her desk reading an "IMPGOSSIP" magazine and drinking a bottle of an unknown beverage, which when she places the bottle on the grimoire a spell activates and a portal opens, allowing Blitzo, Moxxie and Millie to return from killing a bunch of lumberjacks.

After Blitzo returns home from going to Ozzie's, he sees that Loona had left him a note saying she was going to a party with Tex and she would be back late.

"Queen Bee"
Sitting in a car outside Beelzebub's mansion, Loona rejects a call from Blitzo. After leaving the car Loona texts Vortex and meets up with him and they enter the party together.

Inside the mansion Loona attempts to make friends with a hellhound named Vikki, but the conversation ends up getting heated and Loona yells at Vikki that she was a "massive bitch", making all other partygoers gasp and go silent.

After Vortex brings Loona a cup of Beelzejuice the two watch a performance by the Queen of Gluttony, Beelzebub, but Loona doesn't enjoy the performance and stands looking awkward the whole song. After the performance Vortex introduces Beelzebub to Loona as his girlfriend, making Loona feel bad.

After Beelzebub left the conversation Loona decides to leave and walks out of the building crying and calls Blitzo to pick her up, and which he promptly arrives to do. While in the I.M.P van ready to go home a tall handsome hellhound hits on Loona causing her to change her mind and convince Blitzo to stay at the party together.

Back in the party Loona cheers on Blitzo, even calling him "dad", as he competes against Beelzebub in a drinking contest. Now enjoying her time she begins to enjoy herself and makes some friends, but is interrupted by Beelzebub who is worried about Blitzo's mental state. Loona confronts Beelzebub, but concedes and goes to check on Blitzo.

Loona finds Blitzo making out with a random imp and stops him from continuing his drunken encounters, then she takes Blitzo home and comforts him when he believes he is going die alone.

"Seeing Stars"
Suggested by Moxxie for Blitzo to have a talk with Loona about her attitude with clients, Loona herself doesn't take it too nicely and even beats Blitzo, but leaves him alone angrily after he threatens to replace her (obviously a bluff). Later on, Loona searches for Octavia all around Las Vegas. When she finds her, Loona comforts Octavia about her daddy issues, saying that even though it may seem that dads don't care about you, they really do.
