"Irrelevant, Nagisa's true manifestation is a concept of the Law of Cycles. She is Madoka's  representative. She can't die unless Godess Madoka allows someone to kill her (and Madoka is already far stronger than Demigra)"

That's a  very big strawman. Sealing doesn't = killing. Sealing is a Standard Battle assumption. Seal her away and he's won.

"Same could do Nagisa, and that is irrelevant as well. She has half of Goddess Madoka's powers. (Basically, she has all the abilities Goddess Madoka has except the ones that Goddess Madoka has due to scaling to all the Magica Girls since they are all aspects of Madoka's Law). Goddess Madoka is immune to Power Null."

Demigra is resistant to power null. The Time Breaker masks, which is powered by the concept of Demon God evil Magic, bypasses resistances and immunities to the abilities the Demon Gods have, which includes power nullification

"By destroying the very concept of Demigra, she'll easily kill him."

Possible. But how often would she do this? Before she would get sealed away?

Demigra is also non-corporal in his evil energy state, he can also manipulate laws as he created them in the Demon Realm. is resistant to memory erasure, can also erase to the point you never existed in the first place, Is immortal, the conceptual embodiment of time since he absorbed him.
