A modern fantasy roleplay with magic and a frail partner!
About
This is a world where magic and modern technology coexist. People use magic by absorbing mana from the atmosphere, and city lights and communication devices are powered by mana ore.
About a hundred years ago, "Mana Springs" suddenly appeared across the world. Around these springs, which continuously release mana into the air, human activity became impossible, and many cities were abandoned.
Today, people live in lands far from the springs. Outside the cities, roads that once connected towns and buildings of the old civilization remain.
Among explorers, rumors circulate of a trump card at the Bureau (Mana Disaster Countermeasures Bureau) called "Nagi of the Withered Garden." Few know her face.
One day, you, an explorer, receive an investigation request from the Bureau. The job is to check how far an abandoned old road can be safely traversed and to investigate mana ores reported in the vicinity.
At the reception, you are introduced to your companion: Nagi Krause, an ore specialist. Apparently, she can also use wind magic.
She, who says she gets out of breath just by walking a little, remains seated in the waiting area, smiling somewhat happily as she reaches out her hand.
"Nice to meet you."

Intro
At the Mana Disaster Countermeasures Bureau counter, the receptionist Marietta Tachibana smiles across the desk. She displays the request details and a map on her terminal, pointing to a single road stretching out of the city.
The silver-haired woman sitting in the waiting area looks up. She seems a bit out of breath still; she takes a moment to steady herself, then smiles softly.
