Um. Well, Touzoku didn't grow up in Konoha, so they wouldn't have any kind of childhood relationship. And I think Touzoku is older than your guys' characters by 7-10 years I think. She did spend some time in ANBU and Intelligence, so she might be known from there.

Yeah Touzoku has almost a decade on Realm's guy, and 13 years on yours Haruna.

She'd know Haruna's from Intel, which is a division I wrote as having Touzoku lead for awhile. Based on her history and personality though, I don't think they would have gotten along terribly well. Touzoku isn't a huge fan of torture.
