Well, I found out that the last part for the epilogue had been published for a while now. That was a rude surprise, along with Mangastream literally erasing itself from the net.
Really bummed out by the fate of Souma's mom, though I always suspected that she'd been done in by a sickness or something.
And Souma still tries to get Erina to say "it's good". If he succeeded or not, we are not told.
And thus ends Shokugeki no Soma.
