Tetsu's Links
All she hears about from her former classmate Keda is "Yumi this, Yumi that." She's well aware of the awkward relationship they have but that's the extent of her interaction with her fellow jonin sensei. Tetsu sees Yumi as something of a rival in femininity and gets easily frustrated about her own lack of ... well, boobs. Perhaps with both of them as rookie senseis, there will be room for friendship in the near future.
Sees Tetsu as a formidable friend. Respects her by fighting style, teaching style, and as a coworker in the same village. Although they barely communicate (due to Yumi's schedule), Yumi wishes to get to know her more and spar at least once.
