Hi.

I'm writing a custom Jujutsu Kaisen character. I'm well aware that it isn't official. This character is named Gunnar Stormforer and is a second-year student at Kyoto Metropolitan Curse College, also known as Kyoto Jujutsu High. Gunnar is the son of Yuki Tsukumo and Drage Stormforer, two powerful sorcerers, and as such, possesses immense cursed energy. His cursed energy reserves surpass all Jujutsu sorcerers, including Yuta Okkotsu and Satoru Gojo combined. Still, he isn't a clear superior to Okkotsu in hot combat. They've clashed four times, and each has won twice, the most recent bout coming last year in the Goodwill Festival, which Okkotsu and Tokyo ultimately won. For this reason, Gunnar Stormforer is known as the third-strongest sorcerer. This doesn't please him because he's a competitive spirit, and refuses to settle for mediocrity.

He uses cursed energy manipulation much more than his cursed technique. Ability: Cursed Energy Manipulation. Gunnar can create and manipulate cursed vibrations using his own aura as a medium. He believes vibrations are what bring the universe to life. Vibrations are the root of sensation and locomotion, allowing beings to experience the world around them and move through it. Stormforer possesses the ability to project these vibrations inward or outward, harnessing them to unleash formidable offensive strikes or deploy versatile supportive techniques. The cursed vibrations may be used to supplement the real vibrations in his body. Defense: Gunnar uses vibrations to enhance his perception and protect himself from attacks. Even outside of combat, Gunnar utilizes slightly more cursed energy than the average sorcerer for this purpose. His energy can absorb and dissipate incoming attacks by dispersing them across his body through vibrations, minimizing their impact. This is similar to a kevlar vest, but the thin layer of aura protecting him can also be pulled into his body so they do not detract from his offensive firepower. Offense: Gunnar has the ability to weaponize vibrations to devastating effect, be it through enhancing his strength and speed or creating shockwaves. The former speaks for itself, but something that hasn't been mentioned is Gunnar's ability to fashion vibration-infused cursed energy into deadly projectiles, blades, and balls. Here are just some attacks: Reidur Aukandi Hnefahogg (Furious Incremental Blows): Simply put, this involves Gunnar punching fast. Each of the user's strikes will resonate throughout their target's body. This progressively gets more difficult to block, at least without a specialized defensive technique. Ultra Impact: One of Gunnar's strongest moves, this attack involves both physical enhancement and shockwave creation. A ball of vibrational energy is compressed in a small bubble around his fist. Once impact is made, both are released within the target to devastating effect. It's capable of leveling a mountain, but it harms himself. Borskot (Drilling shot): This is essentially three different blasts of manipulated cursed energy in one, so its strength should come as no surprise. It consists of a central shockwave, orbited by two smaller shockwaves spinning around it in a helix motion. This attack is great for heavy-duty, precision hole-punching. Hence "drilling shot." It can pierce diamonds easily. Pilskudd (Arrow Shot): This involves shaping cursed vibrations into shockwaves shaped like arrows. This attack is on the weaker side Maximum Technique: Lofthringur (Air circle). Lofthringur manifests a powerful tornado made of vibrational energy, capable of cutting down anything or anyone caught in its path. This technique is ln practice similar to a gigantic blender, or a turbine engine as the swirling vibrational energy is capable of destabilizing the very molecular structure of a target, leaving only dust behind. The most powerful Lofthringur is said to be able to flatten entire cities. A lot of technique names are a mix of Norwegian and Icelandic.

I'd like two more offensive abilities. One that involves rapidly firing balls of cursed shockwaves similar to a machine gun, and one that involves projecting vibrations into a target to harm it from the inside-out.

Now, I'd like a domain expansion. A very climactic one. I've mentioned that he cannot expand his domain, so I think it's fine to make this one potentially overpowered. It's supposed to be used in the final battle with Sukuna, perhaps after the defeat of his allies. I want it to look like a frozen wasteland, beautiful yet haunting all the same. And its sure hit to be Ishringur (ice ring), an icy version of Lofthringur. Also some other techniques. Geimskjalfti (space-quake), an overwhelming technique that can create an earthquake in the fabric of reality itself, passing through air or solid material.

Something I forgot is that this does not require a barrier to cast, similar to Sukuna's malevolent shrine. This means it can crush any domain (except Malevolent Shrine) by attacking its weak outer barrier. Also Geimskjalfti is akin to an actual earthquake that can pass through any material. These massive vibrations crack the air itself (similar to Whitebeard from One Piece), and are more than capable of dealing lethal damage.

The fact it can be cast without a barrier means it's projected onto his surrounding environment. It's essentially reality-warping, and as mentioned in Jujutsu Kaisen the ability to cast a domain with a barrier, which might be part of a binding vow, is akin to godhood.

And I'd like a cursed tool. A kind of gjallarhorn that allows Gunnar to attack using sound. These sound waves are weaker.
