>>3861039>>3861114Houkago Translations is still in the process of translating the volume so those extra bits aren't posted much. Sadly there's only 2 more and that's with the new cast.
Riko makes a sound source from the Fuwa Fuwa cd then the next part makes a joke about "order within the next 30 minutes and get another set for free". Then the next is Yukari dressed up as a devil trying to infect her sister but it's revealed to just be a dream. This is what the extra bits look like if interested
