En and ichii will still appear in volume four and the next volumes (as implied by the author on her past posts) but i assume that volume 4 is going to be mostly about the 5 knights and the stone, based on the spoilers of chapter 17 and 18. So a lot of medieval references.
Spoilers.......
*theirs a new vampire character thats already been hinted in the past volumes.
*suprisingly theirs actually more human characters now even though their are only 2 chapters out, megi seemed to made friends with one even when he s in an amnesiac state.
*Sugi will finally know the truth (whether it is about his husband or the secret of the organization, it is yet to be revealed)
I really really really want the next vol about his highness past
I will miss my two cuties
But I want to know what happened to him and his knights
