Need help an a bat issue

[mach3]

In our league last weekend a bat from mizuno that was bought in Japan came up. Unfortunately my Japanese is not good enough to understand anything about the bats composure.

Maybe anyone here knows the bat and can help!
It is a mizuno "Beyond Max"

It is not one the bats shown there but comes out of the "Buw League" Series.

I need to know if it would be legal under ISF rules, but further information about it's composure and it's legal status for ASA play might be helpful.
I don't need an information about the available lists, but hints why it would be legal or illegal.

Has anyone seen a bat like that before?

Thanks for your help!
