(What can he teach Damien... There's so much he has learned this year, from fighting to public speaking and as Damien brought up himself, shogi... Ren hums, politely bowing before taking the seat in front of the other. He's not teaching him anything that requires physical training, so his options are a little limited.)

I can teach you about the coffee blends we have inside. (That's one.) Or some principles of cooking.

Public speaking... (More humming, Ren curling the tips of his hair while he thinks.) Basic Tarot principles... Perhaps Japanese? (He laughs, since there's not so much use for that last one when he is speaking it, and Damien comprehends it.)

I can teach you about Japanese society too, since you've asked me about it in the past.
