I watched the last ep of JJK rn, with Dhruv and Uro, and their techniques are awesome. So im thinking about what to write for these two.
Uro's technique: Sky manipulation. Its essentially spacial manipulation. She can fold it and wield it. That being said, the sky she bends has no mass, but things travel through that space. So she can divert things, but the sky she manipulated always snaps back into place.
And the mass existing within the space/sky she manipulates snaps back alongside it. That is her Thin-icebreaker i believe.
Essentially, she can use the sky as a fucking slingshot. But she can shoot air with it.
Another interesting thing is that escaping her sky manipulation is difficult. When she folds the sky with you inside it, you become incapable of touching her unless she allows it, because the sky will be folded in a way she just doesnt allow it. We see this in all the scenes she strangles and drags Yuta.
Then, about Dhruvs. A bit more tricky:
Essentially, he himself isnt actually that strong. We can guess that because of the way he dies against Yuta. No protective stance or anything. Just death like some random old man.
So why is he powerful? Because his technique shines best when fighting many people who are weaker than him. That is how he conquered Japan.
His technique includes Shikigami. The Shikigami move and every ounce of space his Shikigami moved through becomes something similar to a domain. Those who move through it get injured till death.
Basically, if his Shikigami crosses a street. And you follow the Shikigami in the same path he took. Then random cuts and injuries will pile on against you until you die. How strong are these injuries? It probably depends on the Shikigami. Small Shikigami like Yuta used create small but serious cuts. So the big Shikigami have probably a lot stronger effects. Someshit like instand disintegration.
So yeah, his technique is basically the trail his Shikigami travelled through. You move through that spot, you die/hurt.
Its honestly cool but not that strong. He can barricade places and its great for crowd control which explains how he conquered Japan, but against a strong opponent with enough Cursed Energy, they are probably strong enough to resist the technique.
Ishigori... well. He is kind of boring. Shoots strong Cursed technique. Basically like a laser. Cool character but boring technique. I dont wanna write about him.
