Usogui by Sako Toshio
Partial batch, volumes 01-36/49, English scans by several groups, most prominently Duwang.
So, I wanted to read Usogui... but no one hasn't made a proper batch for it... and just like Haruhi-ism says, if you can't find something, you have to create it by yourself! Ripped mostly from MangaDex (it took a while...)
And here it is, a batch of 36 volumes of Usogui. I will made a complete batch when the last 13 vols are out. Meanwhile, enjoy 36 vols of this gambling epic that's not quite as good as FKMT, but still a very good series indeed.
