In ep 1 of Myriad Colors Phantom World Mai was shaking her body soo hard that her bra came off. Thus why she held her chest all embarrassed like when she finished.

Let’s check it out to see if what people are saying is right.

This is the image showing her embarrassed that her bra came undone.

Let’s check it out in more detail, shall we?

{Bra On}
This is her when she was starting the limbo dance, the hook is in place and her breast are limited to an up and down movement.

{Bra Off}
However, in the next moment you can see her breasts are no longer going just up and down, but are rocking all over the place. This is probably where her bra came off.

So, Mai was forced to continue the limbo with her bra off, and finally, at the end of if all grab her chest in the embarrassed like fashion as shown below.

{Here’s what Japan had to say about it. }

*Well, they sure are putting effort into the details.

*Way to go, Kyoani!

*Well shoot, looks like I gotta watch the anime again.

*I don’t see how a bra could come off just by doing this…

*Kyoani ROCKS!

*Even so, her boobs were totally rocking all weirdly.

*Kyoani does put too much detail in places they really shouldn’t need to…

*Isn’t Ishihara too old to be putting detail like this in his shows? Please continue.

*Kyoani for life!
