Sure, Megumi discovers the truth about Toji being his dad in the manga. It's a crucial plot point that brings about various changes in Megumi's storyline and his relationships with others.
I think it's hard to say which is strictly better. The manga gives a purer form of the creator's vision. But the anime can add new dimensions with its audio and visual effects. It comes down to personal taste and what aspects of a story's presentation you enjoy the most.
As of the latest chapters I've read, Megumi is still alive in the manga. Usually, such major character deaths are significant plot points and would be well-publicized if they occurred.
Sorry to say, but Megumi does meet their demise in the manga. The storyline takes a tragic turn for this character.
The Toji manga panels often have detailed and dynamic illustrations that capture intense action scenes.
Toji Fushiguro is depicted as a complex and powerful character in the manga. His backstory and personality are richly developed.
The coloring in Toji manga is top-notch. It not only makes the illustrations stand out but also helps convey the emotions and action scenes more effectively.
The quality is quite good. The animation has nice visuals and smooth transitions.
Another theme is growth. Megumi's growth as a person and as a sorcerer is often tied to his relationship with Gojo. In these fanfics, Gojo's influence helps Megumi become stronger, not just in terms of his abilities but also in his emotional maturity. For instance, Gojo might teach Megumi how to handle difficult situations, which in turn helps Megumi grow. And of course, the theme of love is there. It might not be a romantic love, but the love between a father and son. Gojo's care for Megumi and Megumi's acceptance of Gojo as a father figure is a central part of these fanfics. It gives a warm and fuzzy feeling to the readers.
It depends on the specific manga you're referring to. Different mangas might have different developments for the character Megumi.
