In addition to Sora and Shiro, characters like Steph might also play important roles. She has been involved in many of their adventures before. And there could be other characters specific to the plot of volume 7, perhaps some new opponents or allies from different races. Since the series often has a wide range of characters from the various species in their fictional world, it's possible that new and interesting characters are introduced in this volume to add more complexity to the story.
The main characters Sora and Shiro are always at the center of the action. Their unique abilities and personalities drive the story forward. In volume 7, we might also see the return of some of the more powerful beings in their world, like the god of their world or some of the leaders of the different races. These characters would bring in their own agendas and power dynamics, which would interact with Sora and Shiro's plans and strategies, making for an interesting and engaging story.
Sora and Shiro are likely to be important as they are the main characters throughout the series.
I'm not entirely sure which new characters are introduced specifically in volume 4. But it's likely that there are characters related to the new races or groups that the siblings encounter. Maybe there are some game masters or representatives of different factions.
The main characters are Sora and Shiro.
The main character, Hachiman, is surely important. His thoughts and actions usually drive the story forward.
The protagonist, of course, is very important. His actions and decisions drive the story forward. There may also be some key subordinate characters that play crucial roles in this volume, perhaps in battles or in diplomatic situations.
Hajime is likely to be one of the most important characters as he is the main protagonist in the 'Arifureta' series. His actions and decisions usually drive the story forward.
Hajime is surely an important character in volume 8. His growth and development throughout the series continue in this volume. His friends like Yue, Shea, and others also play significant roles as they support him and contribute to the group's overall goals.
Ainz Ooal Gown is a given as an important character. He is the lich - king - like figure who rules over his territory. Albedo, his devoted follower, is also likely to be important. She is often at his side, providing support and sometimes her own unique perspectives. Demiurge, with his intelligence and strategic thinking, is another character that might be crucial in volume 17. Additionally, there could be new and interesting characters from different races or factions that emerge as important due to the events in this volume.
Most likely, the important characters in Tensura Volume 20 would be the ones who have been central to the story so far. The protagonist, who has been evolving throughout the series, is sure to be important. There might also be some recurring side characters who play crucial roles in this volume's plot, like his allies or those with special knowledge about the world or the challenges he faces.
Ainz is of course the most important character. His decisions and actions drive the plot forward. Albedo also plays a significant role. She is extremely loyal to Ainz and her actions often reflect her devotion. Then there's Demiurge, who is very intelligent and his strategic planning is crucial in many situations. These characters' interactions and their individual goals shape the story in this volume.
I'm not certain as I haven't read this volume. It could be the main character from the previous volumes still playing a central role.
