Transported in the World of Yorl

It was a typical day in Vacaville, people moving about to go to one place, cars foam the streets. Ivan looks like your everyday highschooler but in reality, he used to be a martial artist, he hunted down black bears and claim their claws as a trophy, he even hunted other people that he deemed 'worthy' to be a part of his games. Thankfully he stopped doing this since he was getting bored, so he asked his teacher aka his father if he could attend school. His teacher was hesitated to have him be in a school but decided to give him a go ahead.
Fast forward, it was his third year in high school, he was picked on a few times but that stopped after a bit because he lacked any reaction when provoke. Soon fourth period came about but halfway through the period the teacher just vanishes leaving only dust and a pile of clothes (think of it as the Thanos snap) Confused but what came even more confusing that a strange person kept about on the screen of everyone's electronics showing a beautiful person in white clothing with wings on her back with a halo hovering above her head. Sooner or later, every person grew some sort of crystal on their arms (think of it as the ARK inventory system in ARK: Survival Evolved), Ivan would encounter some strange things in a different world.
Brandon is basically every ginger in the world, somewhat attractive but rather unattractive at the same time. His life was somewhat of a living hell, his father was a drunk head, his mother pass away due to a seizure. His dog and cat died due to age, his mother's parents died, he lived in an endless hell of depression because of that. Losing loved ones and even best friends. He never had friends aside of his cat and dog they were his best friends in his mind. Like any other student, he went to school, and pray that nothing happens and yet lady luck wasn't on his side, he was transported to another world like the rest of his fellow students but something inside him is very different then before, he felt... Stronger?

Note to all: No, I did not copy the series 'Ryn of Avonside', I was planning to make this series later on, but someone created a series similar but different of mine. Multiple people would help me make this story btw, if you see some changes in grammar or poor grammar in general might be because I have multiple of people helping me on this story. (Note, most of which are my brothers and some being online friends)

Warning! This Series would have gore and strong language inside of it, maybe some sexual content in it I'm not sure. (I'll change the tags if there is any) This series would primarily be focus by a couple of friends because I'm busy making chapters for Quantum Marines and Incident 23. Some chapters would be made by me btw.
