Karma and Cursed Seals were fundamentally the same...?
Tobirama's discovery opened a new window for Yu.
Yes, both Karma and Cursed Seals allowed their casters to reincarnate after death.
But where Karma surpassed Cursed Seals... no, it could not exactly be called superiority. It was simply where the two differed.
Those with great power could resist or control a Cursed Seal on their own, just as Sasuke Uchiha had once turned the backlash on Orochimaru. But Karma's reincarnation seemed far more compulsory. So far, no one branded with Karma had been able to resist the reincarnation process.

"Hmm... the common ground between Karma
