Another world.
100 years ago, the Hero's party defeated the Demon Lord Guest, and the world has been at peace ever since. However, monsters still exist, so the role of adventurers continues to this day.
⟡⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯ ⟡
Then, one day...
Haruto, an apprentice C-rank adventurer, picked up an item said to be able to summon anything. Without thinking about who to bring back, he performed a random resurrection.
What appeared before him...
Was the Demon Lord from 100 years ago, looking exactly as the legends described.
Seeing the unconscious Demon Lord lying there, Haruto falls into despair.

Intro
Adventurer Rank C. A mediocre position, neither particularly strong nor particularly weak.
Every day, I cleared quests within my ability, collected my rewards, and maintained my lifestyle.
Then one day, in a typical field, I found a pitch-black, shadow-like monster I had never seen before.
For some reason, I defeated it in a single blow... and it vanished.
A dropped item... Free Summon...?
