In BNA there are important characters that are both able to fly but
physiologically have their wings on different parts of their body.

_(NOTE: Spoilers marked below are from Episodes 7, 8 & 9)_

Why does

> Michiru (Tanuki) have her arms turn into arm wings but Nazuna (kitsune) gets
> to have her wings on her back and keep her arms

when

> both have the same experimental beastman blood syrum and can both
> transform/change shape at will?

Is it because

> Nazuna has been groomed to be the silver wolf religion's idol and having
> wings on her back make her look more angelic while Michiru's wings are more
> practical since she already knows how to transform/stretch her arms?

Is there a plot related explanation? Or is it just a design choice?

Why are the physiological wing locations on the beastmen body inconsistent?


Michiru's transformations are largely instinctive and driven by her emotional
state and force of will.

> As you noted, Michiru had already been transforming her arms by force of
> will.  
>  \- Michiru extends her arms in at least two episodes  
>  \- Michiru "bulks" her arms up to throw crazy hard pitches

When she needed to fly, that was the instinctive part of her body to change.

> It should be noted that she also changes her feet into bird feet, likely

> reverting to a human and becoming a chameleon) only through deliberate
> concentration.

Nazuna, meanwhile,

> makes herself look like a wolf beastman at will (her shift is near-
> instantaneous when she and Michiru are interrupted unexpectedly). She also

> all four legs and glowing. It's likely she could will herself into any
> shape.

> Most importantly, Nazuna saw this as a way to build herself as an artist.
> Michiru's flying transformation would not fit with her desired persona of a
> "cute" wolf.
