I started to read the translated LN, because of the first manga chapter. The story is great so far. The mangaka did a great job on chapter 1, but chapter 2 is so freakishly rushed! He skipped so many things! I know, you don't want to read through a wall of text, when you read a manga, but he skipped out to emphasize just how expensive the boat and ammunition really was for his familiy and how dangerous his suicidal travel was. (Deep into the nothingness, not knowing if this island really exists.) How did he find that island? By writing down all he could remember right after he incarnated, including the coordinates. 3 or 4 more pages would have made such a difference.
The mangaka did choose a great story and he can do it right. Chapter 1 was great. Chapter 2 wasn't awful, just rushed. I'm looking forward to the next one.
