Solo Leveling
Starts with a weak awaken guy with his group and they discover a double dungeon and from it he was one of the survivors from the dungeon. While he almost died he was gifted with the ability to become stronger but he doesn't understand it yet (around 160 chp) and the setup is game like to become stronger like levelling up (get it). From the power he is also met with great responsibility. <3
Naruto
A lot of emotional roller coaster throughout the manga (tho lots). This boy, named Naruto has a lot of history that some people have kept from him reason as he was hated by his village but their was some special people that accepted him for him. As his goal is to become Hokage that many people respect, he wanted their respect as this was his goal for life but his best friend, lead the opposite path from him as they have similar past but ended up different roads. So, his other life goal is to bring back his best friend from the darkens. As Naruto is weak with talent and a sore loser he gets stronger to protect the people he cherish and help.
