The next morning.
The doctor came in for a check–up.
The door clicked open, and a doctor in a white coat stepped inside, holding a clipboard in one hand and adjusting his glasses with the other.
"Vanitas Astrea?"
"Yes, that's me."
The doctor approached.
"Firstly, you've been using magic without a medium, correct?"
"Yes."
The doctor sighed, lowering his clipboard slightly.
"It's fine for Master–ranked spells and below, but anything beyond that…"
He adjusted his glasses, his eyes narrowing.
"You'd risk permanent nerve damage or, in the worst case, lose an arm."
"I see…."
Of course, he was aware.
But what he hadn't been aware of—at least, not until Soliette mentioned it—was that his spell back in Index had reached the firepower of a Grandmaster spell.
"I strongly advise you to start using a medium as soon as possible."
"Understood."
The doctor gave a short nod but didn't move.
