There is one problem with that. Rias is power-wizard type. Those who are technique type can control their power like their own hands and feets, like Sirzech. Power tyrpe are more of releasing all the power, resulting in total damage and death.

But it would be cool though to see Rias turn into a Power of Destruction Humanoid.

One other thing: Even Kings can lead his/her servant on the front line too. I am just saying.
