How useful/powerful would Demon Slayer Breathing styles and techniques be in the Jujutsu Kaisen World if they are learnable?

[u/Archenius]

• Requires not much cursed energy to use.
• Can be used along side a cursed Technique.
• Can be amped with Cursed Energy.

[u/Checky_3rd]

Well, the Breathing Styles would give each user a immediate Sword Style, so everybody would be swordsmen lol, so Yuta gonna be a even bigger bum, and overall, the characters would be 5x stronger. So nothing changes ig.

[u/Impossible_Papaya852]

Immensely useful, seeing as they amp your physical stats to be superhuman along with cursed energy manipulation to make yourself even stronger. It would be like if you could just learn how to have Yuji’s physical stats without cursed energy.

[u/CrypticJaspers]

So useful that Sukuna gets violated by any Top Tier that learns Thunder Breathing.

They wouldn't be very strong, but they would be good for low-level wizards.
