Profile
Broca, former Siracusan mafioso, later became a member of Chiave's gang.
After a certain incident, he joined Rhodes Island along with the leader, Chiave, and now serves as a frontline attacker.
Clinical Analysis
Imaging tests reveal blurry outlines of this operator's internal organs, clouded with abnormal dark spots. His circulatory system shows an abnormally high rate of Originium particulate matter, with other signs of Oripathy infection, we can confirm that the Operator is Infected.
[Cell-Originium Assimilation] 7%
Originium crystals are visible across the surface of his body, but not to a great extent. Symptoms have been effectively controlled.

Although the current situation is relatively stable, due to the late treatment time, his condition may deteriorate.

A Feline male of few words.
His expressions are always menacing and make him seem unapproachable to most. However, if you communicate with him in-depth, you will find that he is a very honest person.
The reason for his expression seems to be that he was conditioned to do this during his time as a mafioso.

Even after joining Rhodes Island, Broca did not conceal his animus towards Rhodes Island, which caused some dissatisfaction among other Operators. However, this was not without reason.
To be more precise, his animus is not directed specifically at Rhodes Island, but towards all large organizations in general. According to Operator Aosta, who detailed his past experiences in the gang, the mafia family to which he originally belonged betrayed him, after which he was rescued by Chiave and Aosta.
It is not difficult to understand his loyalty to Operator Chiave and Operator Aosta, as well as his aversion to large organizations.
While Rhodes Island by no means is an organization that easily abandons its members for immediate benefit, it may take some time for him to understand this.

Though he displayed remarkable prowess on the battlefield, even more surprising about Operator Broca is his talent for handicrafts.
Unlike Aosta, who is skilled at sewing, he is adept at crafting. As long as suitable materials are available, he can make all kinds of tools and equipment according to requirements.
After this was discovered and circulated by other Operators, Broca quickly became a star among his colleagues, taking jobs ranging from making costumes for certain holidays to more important operation requests.
More importantly, he gradually found his position at Rhodes Island by doing these things. Some Operators in Logistics Department even hoped that he could lay down his weapons in favor of a full-time production job.
In the end, upper management approved the purchase of a workstation for him, as well as other supporting facilities, in the hopes that he can continue to develop his specialty.

As Operator Broca himself stated, 'I have nothing against taking orders, but I don't like fighting without knowing why I'm doing it.' After learning to be less defensive towards Rhodes Island and gradually finding a sense of belonging, one can clearly feel the change in his attitude.
The enemies of Rhodes Island are now his enemies, the partners of Rhodes Island are now his partners, his relationship with the Doctor changed from that of suspicion to one of watchfulness, and he has also demonstrated his reliability to other Operators. As far as anyone can tell, he has completely integrated as a member of Rhodes Island.
Though every new recruit to Rhodes Island agrees with our core philosophy and, as of right now, our ranks consist mostly of new members added over the last two years, few have truly come to regard Rhodes Island as 'home.' Of course, we do not require this of all our Operators. In principle, we do not mind becoming a springboard for our Operators, provided that they do not damage the interests of Rhodes Island in the process. However, because many of the old soldiers who truly loved Rhodes Island have been taken away by the flames of wars past, we do have a need to cultivate the next generation of those who can become our bedrock.
Of course, this means that Rhodes Island will have to live up to its tenets, or do even better. Only this way can talents like Broca live in peace here. Only this way can we further traverse this bumpy road.

In a gloomy jail cell, not one glimmer of light hangs about. Behind the bars, a respectably dressed gentiluomo wrinkles his brow in revulsion. In a shadowy corner sits a loud-mouthed man.
'Signore, you got any bros?'
Hearing him utter that specific word, 'bros,' the gentiluomo haughtily pulls at his sleeve collars, and speaks boastfully.
'My elder brother Davis, Signore Davis to you, is an important man in the Eastern region. He has many a means up his sleeve. I won't be loitering in here for long.'
'Nice, nice. I've got a buddy too. Bet you he's also trying every trick to get me out.'
'My brother has a lawyer who charges four thousand an hour. What does your 'bro' have?'
'A giant drill? Plus some insanely buff arms. No joke, chiseled like a rock.'
'Oh? And how is he going to rescue you from this place? Punching a hole in the wall?'
'Haha, yeah, that's just his style.'
Letting out a disdainful sneer, the gentiluomo folds his arms and silently mocks this man in his head, 'Doesn't he know the walls here are half a meter of cement? What an utter dunce.'
The door creaks open, and in comes a man carrying paperwork, his leather shoes gleaming unusually brightly in the dim of the cell.
'Signore Hengel, my pleasure. I'm your brother's attorney.'
The gentiluomo pats off his suit and gingerly stands.
'Are you here to let me out?'
'Sincere apologies, Signore Hengel, but I cannot.
'Your brother wanted me to deliver you a message: 'Enjoying the benefits of the famiglia comes with a duty to the famiglia.''
At these words, the gentiluomo's eyes grow wide.
'But it was my brother who had me do those things...'
Yet the lawyer gives him not even another glance, merely a parting remark as he turns to leave.
'Brothers must help each other out, no, signore?'
'Stop, wait, come back! You bastard!'
The gentiluomo clutches at the bars and begins to wail. The man in the corner attempts, at least, to comfort him.
'Maybe you can come with us.'
'Pull your head out. Your 'bro' isn't coming.
'Everyone who lands in here, without exception, is someone their famiglia cast away.'
'...Famiglia? It ain't anything like that. He's a buddy to me. He'll come.'
'Enough, you moron. Even setting aside how heavy the guard is out there, this wall alone is fifty whole, '
An earsplitting drilling noise cuts off the gentiluomo mid-sentence. Through the wall steadily pokes out a gargantuan drill, wrecking the concrete at such speed it may as well be shredded paper.
Dust and debris is thrown down in spades, and the ground itself lightly trembles.
A burly man steps through the yawning hole, toting the giant drill by hand. The light shining in from behind him hides his face in chiaroscuro.
Casually turning off his handheld titan, the man turns to ask something to the dumbstruck gentiluomo.
'Are you coming with us, signore?'

- Appointed as Assistant
- Stand guard? How annoying... Fine.
- Talk 1
- That Amiya girl is one of this place's leaders? What a black-hearted company Rhodes Island is.
- Talk 2
- I'm not about to freeload here. Just let me know if you need some elbow grease.
- Talk 3
- I have nothing against taking orders, but I don't like fighting without knowing why I'm doing it.
- Talk after Promotion 1
- My hobbies? Why should I tell you? Ugh... Alright, alright, I'll tell you. Just stop making that face... I like tinkering.
- Talk after Promotion 2
- Without Chiave and Aosta, I'd be a corpse in an alley. I owe them my life. So no matter what they want, I'll help them without a second thought.
- Talk after Trust Increase 1
- I don't hate you, but... I find it difficult to fully trust you.
- Talk after Trust Increase 2
- Do what you're told, keep the wolf from the door, live life. They all seemed like simple ideas once to me... But Aosta was right. In a country like Siracusa, things like those aren't ideas, they're dreams.
- Talk after Trust Increase 3
- I gotta say, your leadership skills are decent... But Aosta once said that an organization turns rotten when people let their guard down. So, I'll be keeping a close eye on you.
- Idle
- Asleep? What a carefree Doctor... Gah, where'd the blanket go…?
- Onboard
- Since Chiave decided I'm joining you, I don't have much else to say. You can call me Broca. I'll follow your orders, but don't count on me doing anything extra. I have no love for big organizations like yours.
- Watching Battle Record
- Thanks.
- Promotion 1
- A raise...? Don't particularly need one.
- Promotion 2
- Maybe Aosta was right, maybe Rhodes Island is actually trustworthy. And if so…
- Added to Squad
- Alright.
- Appointed as Squad Leader
- ...I'm not good at leading.
- Depart
- Let's go.
- Begin Operation
- Time to fight.
- Selecting Operator 1
- Don't try to micromanage me.
- Selecting Operator 2
- Tch... Got it.
- Deployment 1
- Are those the enemies?
- Deployment 2
- I can handle it.
- In Battle 1
- This won't hurt for long.
- In Battle 2
- Let's get this over with.
- In Battle 3
- Die, you moron!
- In Battle 4
- Shaddap you face.
- 4-star Result
- Alright… You've got a few tricks.
- 3-star Result
- They've all been taken care of.
- Sub 3-star Result
- Need me to go after them?
- Operation Failure
- Relax. You did what you could. Even Aosta makes mistakes.
- Assigned to Facility
- I'll take a look around.
- Tap
- Hey…!
- Trust Tap
- You're pretty annoying, Doctor.
- Title
- Arknights.
- New Year's blessing
- Happy New Year, Doctor... What? I have to pay for my freeloading. Besides, occasions like these are incredible to me. Comparing to my time in Siracusa, Rhodes Island is decent.
- Greeting
- Morning.
- Birthday
- I've never given anyone a present before, so I'm not too good at picking. Aosta said I should make one myself. Here, it's a block of carving wood, anti-mold treated by me. Tung oil, stops it rotting. When I'm not around, you can move it in front of your desk, and treat it like I'm supervising you.
- Anniversary Celebration
- I didn't think I'd run into you here. I just finished cleaning up my workbench, there's been a lot of orders in for weapons lately. Why haven't I been supervising you lately? Because you don't seem like you're about to turn rotten these days. And I approve of your goals. Let's work hard together, Doctor.
