Help Please

Looking for a colored manga with a picture of a guy with poker chips on the cover (which basically has nothing to do with the story lol). WARNING! CONTAINS SPOILERS! DONT READ AFTER THE FIRST FEW SENTENCES, EVEN THOUGH I STAY RELATIVELY VAGUE! He was a gambler who was borrowing money from this one girl he knew and he lived on the street. He sometimes had dreams of how his life was the last time he lived it. He gets invited to this other world where he has some special privilege because he got invited and wasn’t in some kind of contract like the majority of people. He and a group of other people basically go thorough this nightmare like trial and he racks up crazy amounts of points and they are then brought to this second stage where they meet up with different groups of people like them from all around the world. He got first place in point earning and gets this special room. He also earned so many points he got to go to this special vip store or something. His guide was a short blonde person who wore a suit but who hated this other guide who was also a blonde woman I think. In the second stage they end up having to do quests or missions or something and have to earn a certain number of points to enter a world called ‘paradise’. He has enough points but still ends up doing this skeleton mission thing and gets really scared because he almost dies. He then decides he needs to train his body and ends up running this track thing and eventually, after a boot camp with one of the instructors, he ends up taking more missions. He has the ability to become a mage but chose to become a warrior. Can’t remember much else. I would definitely recommend it to someone who hasn’t read it yet. If you can remember the name, please remind me.
