Profile
A street girl of Columbia, born to a normal working-class family. Her parents are both truck drivers and often work through the night, pushing Aciddrop out to the streets at a young age. From practicing skateboarding in her spare time after school to becoming a champion at local skateboarding tournaments, Aciddrop has become a renowned street icon throughout the city, and her success has drawn countless haters in the process. During a deliberate fight, Aciddrop was infected with Originium dust, later coming to Rhodes Island to seek treatment.
Clinical Analysis
Imaging tests have shown the outlines of her internal organs to be indistinct due to abnormal shadows. Originium granules have been detected in her circulatory system, confirming her to be infected with Oripathy.
[Cell-Originium Assimilation] 4%
Operator Aciddrop's Oripathy is currently still mild, and no Originium crystals have been found on the surface of the body.
[Blood Originium-Crystal Density] 0.15u/L
Aciddrop was infected as the product of manmade accident. Fortunately, the amount of Originium dust she inhaled was minute and the infection is being handled appropriately. No trend of deterioration present.

Miss Aciddrop is an extremely 'hip' girl. This is not solely due to her interest in skateboarding, graffiti, and rap, but also due to her strong temperament. This is reflected through her open-minded attitude towards all things in life— even when undergoing a series of examinations for her Oripathy, Miss Aciddrop would only lament that she had to postpone her cycling trip, as if her free-spirited travels were of greater importance than her condition.
By the way, Miss Aciddrop is not 'interested' in street culture. According to her own account, she was actually quite famous in her hometown prior to becoming infected: she had won many local skating competitions, children all wanted to learn how to skate from her, and she shared sibling-like bonds with some of the street artists there. —Though I first thought this was simply the boasting of a street girl, we discovered that a certain line of a famous, trendy sports brand really had plans to feature her as a model. This certainly surprised us.

During her operator assessment exam, Miss Aciddrop demonstrated an unexpected talent for sniping— strictly speaking, a very flashy talent. Though the mobility granted from being able to shoot while on a skateboard is of dubious value in actual combat, this Liberi's agility caught many operators off guard. 'It's like she's performing for a crowd,' one operator from the HR Department remarked.
However, let this not overshadow the fact that Miss Aciddrop's proficiency with a hand crossbow is not inferior to her skill on the skateboard. It is said that she learned these skills from an old local policeman. As a student, Aciddrop was report to the police for 'excessive graffiti,' and was chased around three blocks by an old, seemingly-weak policeman. Afterwards, she was subjected to a scolding that was dozens of minutes long. After such incidents 'accidentally occurred several more times,' scolding soon turned into chatter, and the kindhearted old policeman seemed to take pity upon Aciddrop, for her parents were almost never home, leaving her to fend for herself. Intentionally or otherwise, the old policeman let his daughter become friends with Aciddrop, since the two of them were the same age. It is this daughter who first taught Aciddrop how to skate.
'Of course, the pupil surpassed the teacher, eh?' Miss Aciddrop would happily proclaim.

Aciddrop's hometown is located in a rather remote location in Columbia. The vast land and undeveloped economy there were rich breeding grounds for the gray market to flourish. The Siracusan Mafia, local gangs, and large merchants frequently made their way in and out, and though this shady area was kept relatively orderly, the general public security is far from ideal. In order to give the young and energetic children a means to protect themselves, after hesitating again and again, the old policeman taught Aciddrop the basic techniques to operate a hand crossbow, and also made a simple weapon for her— after all, he believed that Aciddrop has a strong sense of justice and was not the kind of child who would do bad things with a weapon.
Unfortunately, there were some issues with Aciddrop's loose definition of justice. During an unexpected auto accident, the brave Aciddrop unintentionally destroyed a gang's illegal Originium trading plan, triggering retaliation from the affected gang members. During a brawl that was disguised as a case of school bullying, gang members who were even younger than Aciddrop sprinkled Originium dust onto her.

However, Aciddrop is not one to dwell on the past, demonstrating the perseverance and strength that her youth affords her. This perseverance has supported her to face the painful aspects of life, or in other words, allowed her to take her mind off from the pain. Perhaps one day, after Miss Aciddrop's Originium is effectively suppressed, she will choose to return home. Even if she can no longer take off her identity as an Infected, she feels as if she must complete the journey she failed to finish.
'A toast to freedom, a toast to onion rings, and a toast to myself.' —Excerpt from a speech made by Miss Aciddrop on her first day at the dorms, when she threw a cocktail party using carbonated drinks rather than liquor.
Promotion Record
Recently... There have been some bizarre rumors aboard Rhodes Island. As we are fairly tolerant of various cultures, pop culture among the youth is, of course, rather interesting. However, due to invisible individuals playing super loud hip-hop, graffiti appearing out of thin air, and a skateboarding trend that has spread like wildfire across younger operators and patients alike... If possible, shouldn't we try to dial things down a bit? What do you all think? —The 'suggestion' of a highly-respected logistics operator to young operators such as Ethan, Aciddrop, and Vigna
However, after refugees were rescued from the ruins of a Catastrophe area, you all tagged 'Never say die' on the walls of the ruins. I can't say I'm not a fan. —A subsequent word of appreciation added by the respected logistics operator

They crossed the line.
The Siracusans... and Victorians... and Bolívarians. They injured an innocent child. And they stopped up the station door with bills... Should've known Columbia was like this. Always has been.
No one who could've helped that kid. Went by the nickname 'Aciddrop.' Got into competitions. Glowed like the sun on the outer dunes back then. Now she caught Oripathy. Whereabouts... unknown. I wind this tape up, that marks one month she's been missing.
Still remember how I taught her to use a crossbow. Spark in her eyes, same as my wife and kids. Touched your heart some more than a breeze in the woods, and my girl, girls, [CHUCKLE], I thought to myself back then how I pretty much had two goddamn daughters. 'Aciddrop.' She was like part of our family. Like candy. Sometimes her father came, checked in on her. Gaulish man, built strong. Nothing but guilt and love in his eyes whenever he looked at his daughter. He and I drank. He said he didn't know how to be a good father. Could've said the same myself.
Used to figure with how our families knew each other, be one of the few fancy things in my old age, but that all changed. Overnight. Kid, uh... left two skateboards here with me. The ones I 'confiscated.' Dumped them in the junk room too. Rolled right under that army sword from Bolívar.
I'm just an old guy. Saw these things happen before, never concerned me then. Wanted to do something... only today decided what. I know, look at me, death of a salesman. Best decision maker zero years running. Heh.
[SILENCE]
Taping two copies of this. Remember to send one to the kid if anyone finds her. I'll teach you how to fry onion rings for it. Secret's in the cheese.
[SILENCE]
They've got the smarts to stick with their own. Not much chance I come out on top. Feel sorry for my girl. Her dad shouldn't be taking a risk like this. Makes me glad, though... I fessed up about all this and she was in tears. Gave me the go-ahead.
[SILENCE]
Hey, kid. My daughter's all grown up now. How about you? Where you at?
No matter where you are, I bet you'll get along just fine.
Gangs. Hah. They gonna be scarier than the Steam Knights? Fire raining from the Witch King's spire?
[SILENCE, POURING LIQUOR]
Remember this, kid.
'Cheers to freedom, cheers to onion rings, and cheers to me.', Video cassette, previously held under strict safekeeping at a police station, sent to Rhodes Island after a case of station theft. Sender marked 'Onion Ring Alliance.'

- Appointed as Assistant
- No problem, Doctor. I've got your back.
- Talk 1
- How do I aim while I'm skatin'? It's a piece'a cake, no sweat. Wanna see? C'mere, put your hand on mine.
- Talk 2
- Back in the day, me and my friends thought it was sick as hell to be different. But once I got infected, I found out that wasn't cool at all. You don't let a little Originium dust run your life, you gotta grab the wheel n' steer.
- Talk 3
- An old cop taught me how to shoot a crossbow, n' his daughter threw in skateboardin' lessons. How'd I put 'em together? Pure street genius, straight up self-taught.
- Talk after Promotion 1
- Don't get it twisted, skateboardin's just one of my jams... It's the first way I ever really found myself. But the good stuff comes after that. Wanna hear the whole story?
- Talk after Promotion 2
- Why'd I wanna be a combat operator...? Doc, lemme ask you: what's the one thing us rowdy street kids really live for? Freedom, straight up. I'm cool to throw down for freedom, an' that's why I'm with Rhodes Island.
- Talk after Trust Increase 1
- I'm real broken up about bein' Infected, y'know? Like that park mural I was sprayin', left that one half-done. And I'm never gonna get those secret-recipe onion rings from that old cop again. Huh? That's all.
- Talk after Trust Increase 2
- I came to Rhodes Island to get some help with this disease. Thought it'd be some sterile place that reeked of disinfectant, everyone all shut up in their rooms... But man was I surprised. Even though you don't allow tagging inside the cabins, that Ethan guy... Y'know what, never mind.
- Talk after Trust Increase 3
- I figured out how to express myself with donut hamburger combos, skateboarding, and rap battles. What's your deal, Doctor? If you're feelin' burnt out, come kick it with me and Vigna. We'll... hang out. Hanging out is in our DNA. Gotta respect that.
- Idle
- If you're tired, just go rest. I'll be here.
- Onboard
- Aciddrop, Operator. This skateboard's a registered piece of equipment, got it? Any issues, just hit me up.
- Watching Battle Record
- Damn, that's cool.
- Promotion 1
- A promotion, huh? Thanks. Tryin' to remember the last time somethin' like this went down. Gotta be after I won the Crab Cup…
- Promotion 2
- The old man taught me to use a crossbow just so I could protect myself from the streets. Who woulda thought I'd end up usin' it to defend the freedom of the Infected.
- Added to Squad
- You got it.
- Appointed as Squad Leader
- Teamwork's an important part of scoring too.
- Depart
- Let's roll.
- Begin Operation
- Enemy sighted.
- Selecting Operator 1
- I'm right here.
- Selecting Operator 2
- C'mon, how should I deal with these guys?
- Deployment 1
- Now I'm all pumped up.
- Deployment 2
- Some sweet terrain to ride.
- In Battle 1
- Ollie!
- In Battle 2
- Time to show off a bit.
- In Battle 3
- I'm over here.
- In Battle 4
- Kickflip, then kick ass.
- 4-star Result
- Good work out there, Doctor... Oh, could you help me swap a couple of bolts when we get back?
- 3-star Result
- That moment you clear a challenge always gets me all hyped up.
- Sub 3-star Result
- Should we chase after 'em? If you ask me, I can still catch up.
- Operation Failure
- Ugh... Can't believe this amateur wipeout...
- Assigned to Facility
- This looks perfect for a throw… Uh, I didn't say nothin'.
- Tap
- Wahh!
- Trust Tap
- Wanna head to the canteen together? If I nail this trip without any wipeouts, promise you'll treat me to some juice.
- Title
- Arknights.
- New Year's blessing
- Oh, Doctor, Happy New Year! We've got a block party in a bit. Why don't you come show off your moves? You could give breakdancin' a shot? It ain't that hard, I'll teach ya!
- Greeting
- Hey, Doctor.
- Birthday
- You're still working? Let's go get some exercise outside. Wait, you volunteered for overtime? Doctor, ain't no point in workin' this much. Life only begins once you clock out! C'mon, what do you wanna eat? It's on me.
- Anniversary Celebration
- I used to skate to ditch class n' get away from the adults. Then, it was to lose the cops when I was out tagging. I said I did it in the name of freedom, but thinkin' back, I guess that was kinda selfish. We fight harder for other people's freedom than our own, don'tcha think? Like what we're doin' here.
