Last bonus chapter to the series, I will most likely not purchase the physical tank and just wait for the digital edition to be sold unless someone can confirm with me that there are additional contents only available to the physical tanks.
Also, support the artist when you can, SnO has a skeb account taking commissions for an illustration for a fee. Everyone can now have that certain SnO character do that certain thing that fits your kink that he never got to doing lol.
