Profile
Aosta, former Siracusan mafioso, later became a member of Chiave's gang.
After a particular incident, he joined Rhodes Island along with his leader, Chiave, and is now active as a front-line attacker.
Clinical Analysis
Imaging tests have shown the outlines of his internal organs to be indistinct due to abnormal shadows. Originium granules have been detected in his circulatory system, confirming him to be infected with Oripathy.
[Cell-Originium Assimilation] 5%
Small traces of infection are visible on the surface of the body.
[Blood Originium-Crystal Density] 0.23u/L
Operator Aosta didn't begin treatment until his infection had spread to a considerable extent. All other indicators are normal, which goes to show he leads a healthy lifestyle. Thanks to this, his condition isn't very severe.

Although he tends to keep quiet, Aosta is a dependable Lupo whose demeanor is almost impeccable.
He may sound a little street with his vocabulary at times, but it's hard to believe he used to be one of Chiave's underlings.
He's cautious, and he thinks his problems through. That has earned him excellent appraisals from all the operators he's teamed up with.

According to Aosta, his work ethic is a product of his time with Chiave.
Indeed, Aosta is careful, if you're feeling generous, but less charitably, he's way too anxious. It's astonishing to see someone as young as him possess such a pessimistic personality, but when you look at Chiave, this perhaps may not be so strange.
Chiave made all the decisions about what to do, Aosta decided how to go about doing them, and Broca did all the hard work. It's clear they made it this far in no small part thanks to Aosta's meticulous planning.

Aosta is the most skilled in handicraft of this trio.
More specifically, he has experience in everything from simple origami to complex sewing. If there's anything he hasn't tried his hand at making before, he's able to make something fairly close after just a few glances.
It's a talent rarely seen here in Rhodes Island—we've also got no plans to hire a full-time tailor here—and that has made him hugely popular among our female operators. He's become far busier outside of his deployments. It doesn't seem like he minds at all, though. He's taken on a variety of requests, and he even seems to be enjoying the work.

Out of the three, Aosta is the only one who has an understanding of Siracusa's inner workings as a country.
Even though he grew up in Siracusa and never traveled abroad, he still understood Siracusa's uniqueness. As we all know, the way Siracusa operates is fundamentally different from how other countries are run. There, the families run the show behind all public affairs.
Thanks to this unique characteristic, life in Siracusa is quite strange even in this diverse world, and Aosta understands clearly that the Siracusan lifestyle is not what people of other origins would consider normal.
It's difficult to say what makes a normal lifestyle and what doesn't. However, when the authorities avoid getting involved with the wars between families, it's safe to say that life in Siracusa can hardly be called normal.
Aosta knows so much about the environment he grew up in, and still manages to harbor such doubts about the place. You don't come across people like that often. The good thing about this is that he was able to adjust to life in Rhodes Island very quickly. Unlike Chiave, who took a very long time just to accept and follow the rules here.

Module record
The night streets of Locomotiva City are teeming with armed thugs. Their target is hiding in an alley.
'Aosta, I have an idea. Let's put on wigs, change our clothes, and slip out of the city with the acrobats.'
'Shh, keep your voice down. You'll blow our cover!'
'Hey, I'm serious; I've really thought this one through! We just smashed a pie right in the face of the most notorious don in Locomotiva City, and honestly, he deserved it. But we didn't have time to grab even a single coin before running. Now we're lost, and the streets are full of people ready to turn us into mincemeat. If we don't do something, we're done for.'
'We're not lost. This is the back alley behind Baron's Pub, and there's an abandoned warehouse right across the street. We can hide there temporarily. There's even a working landline inside.' Aosta pulls a city map from his waist pouch.
'And what is this wobbly line here?'
'Our escape route, the one you just ran along!'
'Broca... did you know he planned all this?!'
'No, but it doesn't surprise me.'
'You mentioned a landline, who are you planning to call, anyway?'
'The guy who gave us meds last time. Our car's still with him.' As he speaks, Aosta takes out a business card from his pouch with the words 'Straightedge, Rhodes Island Operator' printed on it.
'I could help him remodel that boring office of his as payment.'
'We were caught off guard the last time we had to flee,' Aosta says, taking out a few coins from his pouch, 'I'm not going unprepared this time.'
'Aosta! You said you didn't have any money for my modding supplies, but you were hiding cash! What else do you got in that pouch? Probably not anything good to eat, though. Ugh... I'm starving. Is there any meat we could roast in that abandoned warehouse?'
Aosta opens his pouch again and takes out two candies in plain packaging.
'I'll never say you're like my mom again! But... only two? If there's one for both of us, what about you?'
'I'm not hungry.'
'There's that mom tone again...'
'Shut up and eat the candy. Do I have to unwrap it for you?'
'Alright...'
He tears open the candies and throws the wrappers to the ground. Chiave's expression shifts from gratitude to confusion to disgust.
'Ugh! What is this?! It tastes awful!'
The white-haired Lupo, who had remained stoic and serious throughout their escape, finally breaks into a smile.
'It's booger-flavored trick candy, to curb your appetite.' He raises a finger. 'The thugs outside have thinned out. Are you ready, you two? On the count of three, we dash for that warehouse.'

- Appointed as Assistant
- I can be your assistant, but is it okay if I do some craft work here?
- Talk 1
- Doctor, if you like excitement, you should probably stay in Siracusa for a while. You won't enjoy it so much after that.
- Talk 2
- Considering his personality, sometimes even I wonder why no one's beaten Chiave to death yet.
- Talk 3
- Doctor, are you interested in DIY? See, the three of us actually design and make our own weapons and outfits. You could join us sometime, if you want.
- Talk after Promotion 1
- After cleaning up Chiave’s messes so many times, I’ve realized something: If you want real power, you’ll need to rely on more than just violence.
- Talk after Promotion 2
- In Siracusa, most people my age just want to join a famiglia, but there are plenty more who would rather live an honest life instead. Sometimes, I think those are the strongest of us all.
- Talk after Trust Increase 1
- (Yawn) …Oh, sorry, Doctor, I didn't get much sleep last night. Rhodes Island is way too safe. It's taking some time to get used to.
- Talk after Trust Increase 2
- Chiave, Broca, and me. The three of us are like brothers, and we've done all kinds of things together. But, sometimes, I really wonder if this really is the life for us.
- Talk after Trust Increase 3
- To tell you the truth, I wanted to be a public servant when I was a kid. Up until my dad made me pick up a weapon for the first time, that is. I don't mind drifting around with the other two, but I always felt like I was missing something, and I know what it is now. I wanted to become as strong-willed as you are, Doctor.
- Idle
- Doctor... you're asleep? You sure live a comfy life, heh? I'm pretty jealous.
- Onboard
- Hello, Doctor. I'm Aosta. It's thanks to you that the three of us are still alive. If you don't mind, please let us work here for the time being.
- Watching Battle Record
- Maybe we're still alive only because of a stroke of luck…
- Promotion 1
- Doctor, is Rhodes Island really a pharmaceutical company? I've got the feeling that we might just be able to take over a Siracusan city if everyone here put themselves to it.
- Promotion 2
- I think I might just be able to live the life I've always wanted at Rhodes Island... Doctor, could I apply to open a DIY shop here?
- Added to Squad
- I hope this isn't going to be too much trouble.
- Appointed as Squad Leader
- I'll give it my best shot.
- Depart
- Let's avoid any unnecessary fights.
- Begin Operation
- Guess we don't have a choice. Let's get this taken care of.
- Selecting Operator 1
- I'll go.
- Selecting Operator 2
- Yes?
- Deployment 1
- Take them all down?
- Deployment 2
- Let me give it a shot.
- In Battle 1
- Hello.
- In Battle 2
- Farewell.
- In Battle 3
- Time to put an end to this.
- In Battle 4
- Tsk.
- 4-star Result
- Doctor, do you enjoy challenging yourself so much?
- 3-star Result
- I got all of them. I just hope they're worth it.
- Sub 3-star Result
- A few of them got through, but I think we'll be fine.
- Operation Failure
- Doctor, you go on ahead. I'll clean up the mess here. It's my speciality, after all.
- Assigned to Facility
- I'll just walk around, then.
- Tap
- I can walk, Doctor.
- Trust Tap
- How are things going, Doctor?
- Title
- Arknights.
- New Year's blessing
- New Year's used to be the three of us hiding in a small room, scraping together a table of assorted dishes to, at the very least, eat something together. And that's all. I never imagined having such a lavish New Year's celebration as this… Don't worry, Doctor, I'll keep an eye on Chiave and make sure he stays out of trouble.
- Greeting
- Hello, Doctor.
- Birthday
- Happy birthday, Doctor. I've never given a gift before, so I'm not sure what you might like… Is there anything in particular you want? Just give me an hour, I may DIY it for you.
- Anniversary Celebration
- Oh, Doctor, I got a lot of orders for props tonight. Did you notice? A whole lot of the decorations hanging around are my creations… Ah, don't worry, I enjoy this festive atmosphere well enough. Would you like me to make you some too? Free of charge, and I'm sure you'll be pleased with the results.
