There's going to be a special chapter released in Margaret on January 5th. It deals with Shishio's life a few years after Suzume and friends have graduated. There will be 32 pgs and it's part of a 100 pg book called "Mini Margaret" with other current serializations in it too.

I guess this is consolation for Shishio fans

So would you say this is an epilogue to the story? Or just Shishio's epilogue?
The ending left me feeling like it was rushed.

Shishio's epilogue most likely, like a side story to his life after Suzume and friends have graduated.
