Ok, I found them! Duality arrangement Album!

How come I didn't know of this? I thought it was like Astral and Umbral without Code.

At least these are the last batch that expire. I will buy the 2 Behemoth/Cait Sith, and the Duality in Christmas, and next year I will go for Nidhogg/Hraesvelgr/Yotsuyu/Tsukouyomi.
Are we sure that Hraesvelgr does not expire? For Nidhogg I saw that in the store page, but the artbook that includes Hraesvelgr doesn't mention anything.

I hope that everything released after these and has codes, that they do not expire ever.

Thanks!
