I honestly thought this was a fresh manga and thats why it had 25 chapters but boy was i wrong, with the guy literally accomplishing his goal in the first chapter i wasnt too surprised it was this short. But to be honest it wasn't that bad of a read and its short, but. They did kinda leave ALOT of lore unexplored, hell we havent even seen the main villain, but if it had continued on it would probaly be another manga at that point which i wouldnt mind if they made an sequel but guess that wont be happening. Its really short, sowhy not give it a try
