Why, an apprenticeship, of course!

"I'll let you live..." The fencer looks up, her eyes brimming with joy, and you almost feel bad for what comes next, "....On one condition."

The fencer, oddly enough, seems to grow happier, hearts in her eyes as she begins to mutter things under her breath. You manage to hear "Gonna fuck me so hard" and "Harder, daddy", and gulp as she finally manages to control her fantasies.

"W-W-What condition?" You can almost see her breath, hot with lust, and you decide that what you say might make her...angry.

"I want you to come with me on a nice, long, hard..." You can see her getting more flustered, her breathing quickening, "....apprenticeship."

"....Eh?"

"What, you thought I was gonna turn you into my sex ****? No, I'm too busy for that, AND I believe in a proper relationship, with dates and stuff, before sex." A raincloud appears over her head, raining down on her as she mutters "B-But my fantasies...." You sigh.

"I'll consider having sex with you, ONLY if you have a proper relationship with me, or if you complete the apprenticeship. Whichever one happens first."

"...."

"Or, you know, I can kill you right now and gain more EXP."

"I'll take the apprenticeship!" You nod and turn to walk away.

You barely hear her mutter "Gonna seduce the living shit out of him tomorrow..." As you leave to prepare for tomorrow. For a butchery, you were pretty popular, if only for the achievement.

Realizing something, you stick your head back in to ask the fencer something.

"Wait, what's your name?" The fencer pouts at you, angry over you not fucking her silly, but sighs.

"My name's Marie. Marie Cruento...."

There, now you can prepare for tomorrow.
