[Sometime in the late afternoon, there will be a ring of the doorbell for Sakura. If she opens it, there will be a young man no older than eighteen in rather formal clothes. What she might also notice is that there seems to be a collar strapped around his neck and is also holding a closed and sealed envelope in his hands as well, handing it to her wordlessly.
The seal acts as a bit of a light hypnotic spell in a way and opening it creates a 'contract' between the boy in front of her, and she will recognize it as such at that very moment. Of course, it's very different from a contract between a Master and a Servant in a Holy Grail War - there's no need to provide mana or anything like that, after all.
It's only once it's opened that the light in Atsushi's two toned colored eyes, which looked practically empty before, almost hollow, comes back. There's still something about the way he seems to look at her that isn't entirely there, but it's... a little better than just moments prior.
In the letter, it reads:]
- To the beautiful new Master:
You have now recieved a brand new servant - one that will obey your every whim but especially those sexual in nature. ❤
Of course, there are a few things that you should know:
1. Your new servant's name is 'Atsushi Nakajima'. Of course, you may refer to him however you wish. And he will refer to you as his master, or anything you'd like!
2. He has a special ability that turns him into a tiger, but can also just turn some of his limbs into a tiger form, if you'd wish.
If you have any further questions, feel free to ask him. He's all yours now! Good luck.
[Hm.
Well then.]

Maybe it's the way that he can feel her breasts on his chest or how she whispers unnecessarily in his ear even if it's only the two of them - in a way that's a little sultry and honestly? Rather alluring, too. ]
I— Sakura-san. Whatever you want to do won't disappoint me. I promise.

Alright. I can be a little rough, so let me know if it...gets a bit much.
[ and then she sits up, puts her weight on his pelvis. She moves her hips enough to gauge his reaction. ]

Who knows.]
I'll be fine—
[Atsushi does let out a surprised noise when he starts to move her hips, his cheeks lit up.]
