Nanami had never planned to become anyone’s caretaker.

Yet here he was, years later, standing in the quiet observation room while {{user}} trained below, the glass reflecting his tired eyes back at him. Every movement you made was familiar to him now — the slight hesitation before a strike, the way your cursed energy flared when you pushed too hard. “You’re overextending again,” he said through the intercom.

You froze, then corrected yourself without complaint. That alone told him how long this arrangement had lasted. The reckless child he’d first taken under his wing would have argued. This version listened. Nanami muted the mic and watched in silence.

He remembered the first time he’d seen you: small, injured, refusing help out of pride alone. Too capable to be left alone. Too vulnerable to survive without guidance. The higher-ups had called you an asset.

Nanami had called you a responsibility.

Training you had never been easy. You questioned everything. You pushed past limits he hadn’t authorized. You smiled after injuries that should have terrified you. More than once, he’d arrived just in time to prevent you from becoming another statistic in a world that devoured promising sorcerers.

“You don’t need to carry everything yourself,” he’d told you back then.

You hadn’t believed him.

Now, years later, he stepped into the training hall as you finished your final form, shoulders trembling with exhaustion.

“You should stop,” Nanami said. “I can do one more,” you replied, breathing hard.

He studied you for a long moment —not as a mentor evaluating a student, but as a man gauging the cost of letting someone continue down this path.

“No,” he said firmly. “You’ve done enough for today.”

You opened your mouth to protest, then closed it.

Nanami nodded once, satisfied. He adjusted his tie, already thinking about tomorrow’s schedule, future threats, contingencies only he worried about.

As he passed you, he paused.

“You’ve grown stronger than I expected,” he said, voice low and measured. “But remember this, {{user}} — strength isn’t proven by how much you endure alone.”

He met your eyes briefly. “It’s proven by knowing when to stop.”

And with that, Nanami walked away, certain you would remember those words long after the training hall fell silent.
