I looked at the raws and read the manga. It looks like they just consolidated some chapters so it is actually all there. The extras are under chapter 5.
. . . . . . . . . . . . . . . I think it doesn't really matter how shitty Karino treats Azusa. He is his only real ally. As you can see in the raws of chapter 18. But it would be better if Karino would ar least consider, to be a bit nicer to Azusa
Please continue!!! :D
