To put it simple, aside from Kagetora's lack of touch and taste in way too many aspects she wants to prove that she can wear what Takeda does but way better, it's like a child trying to brag that she's the best, above, better looking and so on. Plus, white and black hair, white and black jacket and "shorts", green for green eyes and on top of it, she went all the way out to grab a different vehicle to show that she's more skilled at riding them too. She's a grown up woman but has the same knowledge about humanity a toddler does.
