Some of the must-read manga in 2023 include 'Spy x Family' for its engaging family dynamic and spy adventures, and 'My Hero Academia' for its exciting superhero battles and character development.
Sage must focus on character development to make them relatable and memorable. She also needs to pay attention to the details in the background and settings. Another important thing is to keep up with the latest trends in the manga world while staying true to her own vision.
I'd recommend 'Naruto' for beginners. It has great character development and an engaging plot that keeps you hooked. Also, the art style is appealing and easy to follow.
