Description implies typical trashy manga, decided to give it a chance cuz I'm into outdoors and all this stuff and the rating was alright but it's trash. MC is some weird ultra aware bullied kid in school, weird but ok, gets sent to island and almost immediately pulls out a combat knife from his school backpack??? With no sheath??? Then jump to him sprinting through an unknown jungle talking about scouting? Then he finds some magically clear creek and pulls out a filter water bottle (water bottle filters don't even filter out viruses and bacteria but ok). This is literally just survival plot armor and a whole lot of nonsense, the author knows jack about the outdoors but decided to make this manga anyways. If anyone else is actually into the outdoors then this will probably piss you off, maybe other people will be able to read past the bs.
