As a special treat, an extra big update today. Ten (count 'em!) pages at once.
Attached is the first of the batch (page 18), which is a cover page. As you can see, this chapter is labelled "chapter 1".
I can hear you saying: "Then what the hell were we reading before this?!? Chapter 0."
As much as I, being a Computer Scientist, would've appreciated it if they started numbering at zero, that's not the case.
The first chapter of this manga, the one you have already, is called "Tsurai zo kateikyoushi". This new chapter is called "Yariika kateikyoushi, chapter 1". All the remaining chapters of this manga are "Yariika kateikyoushi".
Which begs the question, how does the first chapter fit into continuity. The answer is, it doesn't, at least that's what I think. For one thing, the main guy in the first chapter is called "Takuya", and now he's called "Ichiba". Because they look alike, we might be dealing with a single person called "Takuya Ichiba", I don't know that. What I do know, as is evident from reading the pages of this new update, is that Ichiba at least isn't a tutor yet.
So what I think is that the first chapter, the one with Takuya, was more of an eye-catcher than anything else. Now, starting with this chapter, we get to the real story.
That's just my opinion anyway, I could be completely wrong. If you happen to have a better explanation, feel free to let me know. To quote a certain Vulcan, "I have no ego to bruise".

When the hosting deal with Tman comes through I intend to translate and upload the cover pages and the table of contents, which'll hopefully make this chapter mess a little better to follow for you.
In any case, enjoy the new update!
