It depends on personal preferences. Some people might think Tokyo Ghoul is better for its original story and character development. Others might prefer Tokyo Ghoul:Re for its continuation and new plot twists.
The biggest distinction is that Tokyo Ghoul:re builds upon the foundation of Tokyo Ghoul and expands the world and lore. The character arcs evolve differently, and there are new challenges and conflicts. Both manga have their unique charm though.
It depends on your taste. Some people love the depth of the plot and the evolution of characters in Tokyo Ghoul:re manga, while others might find it a bit too dark or complex. But overall, it has its merits.
To develop their relationship, start with small moments of interaction. For example, Ayato could save Hinami from a dangerous situation, which would be the first step in building trust. Then, have them share their past experiences. Ayato could talk about his family and his struggles, and Hinami could do the same. This would make them understand each other better. Another way is to put them in a common goal - oriented situation, like working together to protect a group of weaker ghouls. Through this, they would see each other's strengths and weaknesses and grow closer.
One idea could be a story where Ayato and Hinami are forced to team up on a dangerous mission. They start off distrusting each other, but as they face various challenges together, they gradually develop a mutual respect and friendship. For example, they might have to infiltrate a powerful ghoul organization's hideout. Another plot could be set in a post - apocalyptic Tokyo where they are among the few ghouls left and have to find a way to coexist with the remaining humans. Ayato's tough - guy attitude and Hinami's more gentle nature could create interesting dynamics throughout the story.
I think there are a specific number of volumes, but I'm not sure exactly. You might want to check reliable manga databases or fan forums for the precise count.
