Will Adult Swim going to rerun Death Note soon in the future?

There was an interview about this in desunoto and they said 'not in the foreseeable future' - I'll take that as a 'no'

B.) No.
They recently announced that they have lost the rights to air Death Note as well as Blood+.

yeah! basically look at the grownup swim episode instruction manual or what ever that's called. if certainty be told right this moment they are going to be showing death be conscious a million! horray for you! right this moment incase you forgot, is july 12. death be conscious would be taking part in each saturday at 12:30 pm, genuine after bleach. beginning right this moment, so hurry up and watch it!

B.

Besides, Death Note was just one plot hole.

C.) Maybe

They have been talking about it. They say if enough people continue to email them about re-airing it then they said that they will put it back on the Saturday Night listing.

I hope this helps.
