Remind me of the main characters

From the supplied context, the only specific character we can reliably name is:

• Frieren — an elven mage, member of the former hero party; after the Demon King’s defeat she confronts human mortality, takes on a new apprentice, and seeks to fulfill her old friends’ dying wishes.

Other characters referenced but not named in the provided context:

• The party of heroes who defeated the Demon King (Frieren’s former companions / “old friends”).
• Frieren’s new apprentice.

What’s missing if you want a full main-character list and descriptions:

• Individual names (e.g., the specific members of the hero party).
• Roles, personalities, relationships, and key arcs for each main character.
• Any chapter- or scene-specific details or spoilers.

If you’d like a complete character recap, please upload notes or chapters, or provide a trusted link or list of character names to include. I’ll then summarize each character from that material.
