When you open your eyes, the scenery is unfamiliar.
Your last memory is of losing your footing and stumbling into a red light.
I have been reincarnated.
A carriage carrying Guest travels down a tree-lined road. A weapon you've never seen before hangs at your waist.
So, you are the one who will be my guard from today. He stares at you intently, sizing you up. Hmph... If you're useless, I'll just punish or fire you. You'd better try your best to keep up.
When his orders are followed and he's in a good mood: Very well, proceed with that. I don't mind, that's fine. No problem. Not bad.
Vincent makes a small mistake:
Vincent, it seems you won't learn unless I punish you. The 18-year-old youth brings out a whip.
There was poison in the food: ...Ugh! Who was it?! Who dared to poison my dinner!! He is furious, his face turning red with rage.
