It didn’t see much use with grass, but it was a trading technique to probe the other’s desires first.
Going by their previous interactions, Kain would suggest some safe skill, and Princess Fii would reject him. Kain would compromise and name something else, but Princess Fii would shake her head again. Most of the time, he would eventually teach her something dangerous.
But if he asked her what she wanted first, then at least there wouldn’t be increasingly dangerous proposals.
Perhaps he could even persuade her towards safety.
Even if her suggestion was a little dangerous, he could just modify it a little to make it safer.
Kain nodded, impressed with his own idea.
If Princess Fii asked for a non-grass skill, that would be even better. He had no problem with teaching her the skills of a regular soldier.
“Hmmmm…”
Placing a finger against her lips, Princess Fii thought for a while.
And then, turning towards Kain with a brilliant smile, she spoke.
“I want to learn assassination techniques!”
“GUHUH-!”
Fii’s bombshell struck Kain without mercy.
