Who are the main characters in the 'oreshura volume light novel'?

I don't know specifically since I haven't read it. But usually, the main character from the previous parts of the 'oreshura' series would be there.

Well, one special thing could be its unique storylines. It might have interesting character developments that draw readers in. For example, the relationships between the characters could be complex and engaging.

Since I haven't read '86 volume 2 light novel', I can't give you the exact main characters. However, in many light novel series, the main characters are often the ones who drive the story forward. They are likely to be the ones with the most complex backstories, goals, and relationships. Maybe in this volume, some new characters are introduced who become main characters or the existing ones from volume 1 have their roles expanded.

I'm not entirely sure without reading it specifically, but likely Bell Cranel would still be one of the main characters as he is central to the series.

I'm not sure exactly, but probably some hardcore gamers who are facing new challenges in the virtual world.

The main character is likely Rimuru Tempest. He's been central to the series throughout. There may also be other important characters like his friends and allies in the Jura Tempest Federation.

Ainz Ooal Gown is the main character. He was a normal gamer in the real world but becomes a powerful undead overlord in the novel's world. Albedo is another important character. She is fiercely loyal to Ainz.

There are likely other important characters as well. Maybe some of his loyal followers like Albedo or Shalltear Bloodfallen. Their loyalty and how they assist Ainz are often part of the story in the Overlord series.

I'm not entirely sure without reading it specifically, but it's likely that Rimuru Tempest is still a main character as he's central to the 'Tensura' series. He has been on a journey of growth and development throughout the previous volumes, so he would probably continue to play a major role in this one.

There may also be other supporting characters that contribute to the story in volume 12. However, without reading it, it's hard to say exactly who else might be prominent. But the three main ones - Hachiman, Yukino and Yui - are likely to be at the heart of the plot, driving the story forward with their actions, decisions and interactions.
