The love leveling manga excels in this aspect. The story is engaging and keeps you hooked, and the characters have depth and complexity that you don't often find in similar manga.
One manga that comes close is 'The Gamer'. It shares some similarities in terms of the protagonist's growth and the fantasy elements.
One manga that's similar could be 'Sword Art Online'. It has elements of character growth and an evolving plot like 'Leveling Up'.
The anime Nana follows the manga quite closely in terms of the main plot and character traits. But there are some small differences to fit the animation format.
The Gate anime is quite similar to the manga. The main storylines and character traits are mostly consistent, but there are some minor differences to make it work better for the animation format.
One manga that could be similar is To Love-Ru. It has a similar light-hearted and romantic tone with diverse characters and comedic situations.
The manga overhaul often provides more depth and detail in plot and character development. But the anime can bring the story to life visually, which has its own charm.
'Hunter x Hunter' is comparable. It features unique powers, strategic battles, and a focus on character growth and their relationships, much like in Naruto.
I'd recommend 'Paradise Kiss'. It shares some similarities with Nana in exploring complex relationships and the characters' growth and struggles.
Maybe 'Honey and Clover' is comparable. It delves into the emotional lives of young characters and their struggles, much like in Oregairu. The art style and character dynamics can give you a similar vibe.
I think Tower of God is quite similar. It has an engaging plot and well-developed characters like SoloLeveling.
