staph saying that teru is the big brother. She is the most girlish of the girls.

and I suscribe with Xavier´s theory. The kanmusus know about a lot of  modern stuff their historical counterparts didn´t know. (They know the end results of their battles, Imuya knows cellphones and yuubari knows about friggin´ late night anime), so it´s no wonder Teruzuki knows about her sis.
