In a world where there are gates to mysterious dungeons and heroes who enter them and defeat the monsters within, Izuku once entered a dungeon which was never seen or heard of, a 'Double Dungeon'. In it, events happen and Izuku gets the power to level up! What happens next. Read to find out. Ever wondered what it would be like if Deku had the power of leveling up from the manga and light novel 'solo leveling'. In this he gets the power of the protagonist of 'solo leveling'. This might spoil some details of the manga to those who haven't read solo leveling. also...sorry if it gets a little dark sometimes. My hero academia belongs to Kohei Horikoshi and solo leveling belongs to Sung-Lak Jang. I only own this plot originally wrote this on wattpad, just re-uploading my chapters here just so they reach a wider audience. hope you all like it.
