If a ghost has zero mass, where does the mass it eats go...

1. Breakdown into gas and expel all of it 2. Convert the mass into energy

In the first scenario, the conversion into gas would cost energy instead of producing any. Therefore it must be the conversion into energy. In that case, the energy absorbed is given by E = mc^2 That is, mass multiplied by the square of the speed of light.

Mysty has a body mass of 30 kilograms. E = 30[kg] x {3x10^8[m/s]}^2 = 2.7 x 10^18[J] The atomic bomb at Hiroshima had an energy level of 5 x 10^13[J], therefore the energy contained within Yuyuko is at least 55000 times the nuclear explosion. If that energy is released...

Dai-chan! Gensokyou is doomed!

What strange things are you saying all of a sudden?

Is your head alright?
