The Love of a Parental Unit

The end of SDBH's 11th installment of BBM in the arcade story ended with a kamehameha heading for Fu, and I had a thought.
Final Form Mira is there, and I thought of this.

Even if they haven't known their son for long, I felt that collectively something like this could be a last display of love by Towa and Mira for their son if it kills them.
I'm a sucker for this kind of thing, and it fits.
Towa and Mira sacrificed their own safety to get their son to safety before Mechikabura's palace collapsed, now they protect him from certain death.
