How Akeno has both devil wings?


In Highschool DxD new Episode 10, Akeno showed her wings to Issei and told
that she have both Devil and Fallen Angel wings. But when I was watching
Highschool DxD Born then in Episode 1 during one fight it showed that she has
both Devil wings.

So is it possible that it is some kind of mistake or there is any explanation
behind this event ? I am not sure but there are few other events too which
shows that she has both devil wings in previous episodes too. But how it is
possible ?

## Spoiler alert

Quoting Volume 4 of the light novel,

> different from the usual two wings of devils, one wing was of a devil and
> the other one was the black wing of a fallen angel.

This is the basis for the scene you saw in High School DxD New.

Now, the background story of Akeno is that she originally possess only fallen
angel wings. She was born of a Miko and a fallen angel. However, due to
persecution from her mother's family, she ran away and then met Rias, who
turned her into a devil, causing her to own both devil wings and fallen angel
wings.

The cover of the novel shows her with demon wings. DxD BorN also shows her
with devil wings.

So, a logical conclusion that we can draw is that

  1. Akeno has both a pair of devil wings.
  2. She can make a pair of both. For example left wing is that of a devil and right is that of a fallen angel or vice versa.
