Well, making mangas involves several steps. First, there's the idea or concept for the story. Then the artist does rough sketches to plan out the panels and composition. After that, detailed line art is done, followed by adding colors or tones. Sometimes, there's also lettering and special effects to make it more engaging.
Mangas are made through a process that starts with a story idea. The artist then sketches out characters and scenes, inks them, and adds colors if needed. Finally, text and dialogues are added.
It's possible. If the first season of the anime based on a completed manga is highly successful and there's enough interest from both fans and producers, a second season can be made. However, factors like production costs and licensing issues can also come into play.
To my knowledge, Koogi hasn't produced any other significant mangas. Maybe they have some lesser-known works or are currently working on new ones that haven't been widely publicized yet.
The number of Evangelion mangas is not easy to pin down precisely. There are the main series and various related side stories and adaptations, so it's a bit complex.
The Naruto manga series consists of a considerable number of volumes. Specifically, there are 72 volumes. These volumes cover the entire story arc and adventures of the characters.
The number of JoJo mangas can be a bit hard to pin down precisely. There are the main series volumes, along with special editions and related works. But you can expect a substantial collection over the years.
