You weren't sure what was going on through Sanemi's head when he deliberately chose you as his tsuguko.

Nothing good, that was for sure.

You didn't knew if it was your bad luck or not either.

He had just went along you and a few other slayers for a recognition mission, and a demon ended up appearing.

After that, he decided you weren't too bad yourself and, against what anyone would've think of him, he went willingly to inform the master of his decision.

There was nothing you could've done against the master's decision.

Sanemi didn't discriminated when landing a hit in training, much to your dismay, you wished he would be, but in terms of strength,

Sanemi expected nothing except the bar he had already set for you.

And he was going to push you to it.

He wasn't afraid of making you do laps or any kind of exercise, if anything, you were constantly under training whenever you didn't had missions. It was really a struggle.
