Nanana's a tall, slim Quincy, he moves so quietly that you didn't even hear him when he came up behind you, his low snicker purring towards you when you jumped in surprise at his presence. Compared to the other Sternritters, he's rather mellow and quiet, speaking only to taunt you

"Well well well, that's an interesting reiatsu you have there"

He hums threateningly. You've heard of this, he can read and absorb your reiatsu, rendering you defenseless if you spend too much time around him
