Why do you think they can settle in a horror setting if they’re under 18?:

Even for a shinobi, Sasuke's life has been rough. When he was a child, his brother murdered his entire clan (Sasuke arrived just in time to see the still-warm corpses of his mother and father at his brother's feet) and told him to spend the rest of his life hating him. Words that Sasuke took to heart for nearly a decade and guided his life from then on.

There was a time when he wavered between his revenge and his bonds, but his hatred won out and eventually brought him to Orochimaru. To explain everything Orochimaru is and his known experiments would take some time, suffice to say he's a man who would do anything to get what he wants. No matter how unethical it may be. Sasuke spent years at Orochimaru's side—not just as his student, but also as a test subject. How far the experiments on Sasuke went are anyone's guess as it's only come up a handful of times in the series before fading into the background. The first mention is when Kakashi notes Sasuke's extraordinary growth. Another is when Kakashi claims Orochimaru would've ensured Sasuke had an immunity to some poisons. Likely because for a while there, Orochimaru intended to take over Sasuke's body (a fact Sasuke was aware of when he joined) and he didn't want to be caught off-guard by poison.

Even without any of that, there are several other reasons why Sasuke should have the mental fortitude for a horror setting. The Naruto world can, frankly, be rather dark and shinobi go through much to prepare themselves for what they'll eventually see. A few noteworthy examples include: a civilian gettting executed after his arms are removed, Ibiki's first-hand experience with torture, a shinobi having his arm blown off and later being used as a sacrifice. There are several other examples, too, including one where Itachi places Sasuke under a genjutsu so he can relive his clan's massacre for 24 hours.

After all he's seen and done, there are very few things that can break Sasuke.

𝖠𝖡𝖨𝖫𝖨𝖳𝖨𝖤𝖲 & 𝖯𝖮𝖶𝖤𝖱𝖲;

Canon Abilities/Powers:

𝘚𝘏𝘈𝘙𝘐𝘕𝘎𝘈𝘕
All the basic sharingan abilities. The sharingan has several different abilities (and has a different appearance) so I'm going to break this down into two lists. I'll try to keep this as brief as I can.

✽ 𝖨𝖭𝖲𝖨𝖦𝖧𝖳/𝖯𝖤𝖱𝖢𝖤𝖯𝖳𝖨𝖮𝖭. The base sharingan gives the user access to several skills. 𝘰𝘯𝘦, they can see chakra as color; 𝘵𝘸𝘰, they can copy another's movements (in Kakashi's case, he typically copies seals and jutsu but can also use it to lipread. Meanwhile Sasuke's grand list of achievements include copying pencil strokes and Lee's taijutsu); 𝘵𝘩𝘳𝘦𝘦, they can predict/anticipate how others will move and read any seals they make (regardless of the speed); and 𝘧𝘰𝘶𝘳, enhanced vision (Madara implies he can see further than Hashirama because of the sharingan and Sasuke uses his Sharingan to see down to the cellular level).

✽ 𝖦𝖤𝖭𝖩𝖴𝖳𝖲𝖴. Put simply, illusions/hypnotism. By making eye contact with someone, a sharingan-user can take hold of that person's senses and place them under a powerful genjutsu. There is no one single use of genjutsu so it's a little difficult to explain what it is and how it can be used, but various people in the series have used it to put others to sleep/knock them unconscious, put them under their control/influence their mind, and extract information. However, most genjutsu can be broken and those with a sharingan have a higher resistance to genjutsu than most.

𝘌𝘛𝘌𝘙𝘕𝘈𝘓 𝘔𝘈𝘕𝘎𝘌𝘒𝘠𝘖 𝘚𝘏𝘈𝘙𝘐𝘕𝘎𝘈𝘕
An upgraded version of the Mangekyo Sharingan. Ordinarily, the strain from using the Mangekyo's abilities would eventually cause the user to go blind. With the Eternal Mangekyo Sharingan, there's no risk to the user's sight. The only way to gain an Eternal Mangekyo Sharingan is with an eye transplant. Each Mangekyo Sharingan is unique and has different abilities as well as a different design.

✽ 𝖠𝖬𝖠𝖳𝖤𝖱𝖠𝖲𝖴. Black flames that appear wherever Sasuke focuses his left eye. Although the flames don't appear to be particularly strong (it takes sometime for them to burn through anything), it's impossible for anyone to put them out. Theoretically, the flames will remain until whatever they're burning has turned to ash. Neither water nor another flame can snuff out Amaterasu.

✽ 𝖪𝖠𝖦𝖴𝖳𝖲𝖴𝖢𝖧𝖨. Kagutsuchi allows Sasuke to manipulate and extinguish Amaterasu's flames with is right eye. This is the only known method to stop Amaterasu, though Jiraiya does seal Amaterasu's flames away earlier in the manga.

✽ 𝖲𝖴𝖲𝖠𝖭𝖮𝖮. Susanoo can only be used by someone who has unlocked each of their Mangekyo Sharingan's abilities.

A large humanoid figure made from the user's chakra that can be used both offensively and defensively. There are several different stages to Susanoo, though for the most part these stages simply mean manifesting more and more of the body and armor to increase its size and power. Sasuke can further enhance his Susanoo by using it with Amaterasu. It wields a sword and a bow.

𝘕𝘐𝘕𝘑𝘜𝘛𝘚𝘜
✽ 𝖥𝖨𝖱𝖤 𝖲𝖳𝖸𝖫𝖤. One of Sasuke's two chakra natures is fire. This is pretty fitting considering one of his first signature techniques was developed by his clan (it's also a coming of age rite for them) and his early mastery of it. The technique in question is the Great Fireball and, to use it, the user builds up their chakra, holds it in their chest, and then expels fire from their mouth.

There are multiple Fire Style jutsu and Sasuke can perform a few more of them, but these days he relies more on Chidori, Amaterasu, and Susanoo than ordinary flames. Not to imply he doesn't still use Greatball, just that it doesn't show up as frequently as his other techniques.

✽ 𝖢𝖧𝖨𝖣𝖮𝖱𝖨. Chidori makes use of Sasuke's other chakra nature, lightning. This attack is a high speed, high difficulty move that anyone without a sharingan may struggle to use effectively.

The standard chidori is performed by gathering lightning chakra in the user's hand and rushing forward. As of Part II, Sasuke has started applying shape transformation to Chidori to make it more versatile (as opposed to basically thrusting his arm and body forward to pierce a person or object). These changes include surrounding his body with a current of Chidori, shaping Chidori into senbons and throwing them, and forming a Chidori blade or even a spear.

✽ 𝖲𝖴𝖬𝖬𝖮𝖭𝖨𝖭𝖦. Unsurprisingly given his connection to Orochimaru—a real snake of a man—Sasuke holds a contract with serpents. Somewhat more surprisingly, he holds a second contract with hawks. Sasuke primarily uses these summons to help him get out of difficult situations (with Manda, he evaded a fatal explosion. With Garuda, he avoided falling from a great height), though not exclusively. Since he's cut off from his world, he's unlikely to have access to either contract.

✽ 𝖥𝖴𝖨𝖭𝖩𝖴𝖳𝖲𝖴. The art of sealing anything the user chooses within an object.

𝘛𝘈𝘐𝘑𝘜𝘛𝘚𝘜
Sasuke's an exceptionally fast, agile fighter with a talent for taijutsu. This is especially apparent in Part I when Sasuke has fewer ninjutsu at his disposal and has to rely on his taijutsu and bukijutsu to fight battles.

𝘉𝘜𝘒𝘐𝘑𝘜𝘛𝘚𝘜
Essentially, weapon techniques. Sasuke has the following two specializations.

✽ 𝖲𝖧𝖴𝖱𝖨𝖪𝖤𝖭𝖩𝖴𝖳𝖲𝖴. Shurikenjutsu is about what you'd expect from the name, it's the art of throwing shuriken, kunai, and other similar weapons. While Sasuke is adept at shurikenjutsu and received top marks for his skills at the academy, this is far from Sasuke's greatest ability.

✽ 𝖪𝖤𝖭𝖩𝖴𝖳𝖲𝖴. As of Part II, Sasuke's become a proficient swordsman and regularly makes use of his skills during battle. Most of his moves are about what you'd expect, with one big exception: Sasuke can channel lightning chakra through the blade. This makes the edge sharper and far more difficult to defend against. Plus, when he pierces someone, it's possible for Sasuke to temporarily paralyze them.

𝖲𝖨𝖭𝖲 & 𝖵𝖨𝖱𝖳𝖴𝖤𝖲;

What is their greatest negative emotion towards an object, situation, or person in their past?:

Hate. From very early on, Sasuke is nothing but honest about his desires. He wants to kill someone—he wants to get revenge on them. For roughly half the series, that person is his older brother Itachi. The situation? The massacre of his clan. Because of what happened to his family and what his brother told him afterward, his way of thinking gradually became warped.

He focused on the negative bonds in his life, prioritizing them over any positive ones. As previously mentioned, there was a period where he nearly escaped that way of thinking. But instead of choosing that path, he delved into darkness and lived his life only for revenge. For Sasuke, it must've seemed like the only choice he could make. His sadness and anger were too great to put aside regardless of any other bonds he had.

So much so that, when he learned everything he believed was wrong and that someone ordered Itachi to kill their clan (as opposed to "measuring his capacity"), his hatred only grew. He forgave his brother, felt sorrow for him, felt guilt, felt pain, and all that hatred he'd spent almost a decade cultivating was redirected toward the ones responsible for the order.

More than the ones responsible. Sasuke decided that the entire village (including the ones who had no knowledge of what happened to Itachi) deserved to suffer. Not even killing one of the people truly responsible for Itachi's circumstances helps satiate Sasuke's anger. The only thing that gives him pause is his brother's words after his unexpected revival. This is the point I'm pulling Sasuke from: a point where he's on the brink of deciding how he wants to direct his anger but needs more answers to determine what he intends to do.

How strongly do they feel about the negative subject matter, on the scale of one to ten?:

A solid ten. I could go on but, like, it's a ten. It's just a ten. Sasuke is a person prone to extremes. Even when he seems calm, it's best not to underestimate how deep his hatred runs or what he'll do next in his quest for vengeance. This can make him a bit unpredictable at times (somewhat ironic given Naruto is meant to be the unpredictable one) and a handful of chapters is the difference between him allying himself with someone or betraying them.

Having said that, I want to repeat that I'm taking Sasuke from a transitional period. Itachi was very much correct when he described Sasuke as a "blank canvas that can easily be dyed any color". Where his directs his hatred as well as how his hate changes in intensity could vary greatly depending on the next bond he makes. Or on a canon update.

What is their greatest virtue?:

This answer is much less clear-cut than the previous one. Surprisingly, Sasuke has displayed several different virtues throughout the series, including ones I won't list for brevity. He's shown kindness, courage, loyalty, and determination. All of these traits are part of who he is, even if several of them have become less pronounced over time. Many of them are linked to one another as well, or one begets the other.

Of only these four, the trait Sasuke displays most prominently is determination. You could also say it's commitment as the two are similar enough that either is accurate. Regardless, Sasuke's had a clear goal since childhood and has thrown everything he has into achieving it. He stayed at the top of his class, he pushed himself more than anyone, and never lost sight of his objective even years after deciding on it. In fact, he's singularly pursued this one thing for so much of his life that even as a child he becomes lost in it, unable to see the people right in front of him.

And to the point where, when he thinks he's achieved it, it seems like he has nothing left for anything else. His vigor returns when he finds a new, albeit linked, goal to throw himself into. Sasuke is, well, he's dedicated. He'll do anything, go through anything, once he's decided on what he wants.

How aware are they of their virtue, on a scale from one to ten?:

Given this page, he's very aware of it. He knows exactly what he's willing to put himself through and he never wavers once he's made a decision. Nothing and no one can stop him. Unless he decides to let them, or they doggedly pursue him for years.

Given that, I'd say this is another ten. After all, he did attack a summit with the five strongest shinobi in the world just so he could get revenge against one man. No one would do that if they weren't extremely determined. And reckless.
