More complete than https://e-hentai.org/g/1943332/743838259a/ (Missing page 28)
When Hagane.F deliveried the pack it is incompleted. He resend the addition pack later, It seems like the gumroad version didn't get this update. The June 2021 pack also missing 1 Medusa variant (image 44) the total image of Medusa is 160. I will upload it later if needed.

Oh ddint know about that update il add page 28 then as per medusa variant the author of that being Korean mentioned adding it later which I think he made a new post about it

I think he means the Glass-less variant as the new post. Hagane.F created 2 folder of Medusa collection in the pack since he named 2 variant version as the same name. reasoff addition pack is the glass-less version, glass version is the one that missing image no.44. I counted every single one of them so i sure about that. The total image of Medusa is 160.
