I do wonder thou. How much suffering Raoul had to deal with when he had to ask the goddess to unlock his dark magic at the beginning? If dark magic requires suffering, then he should have accumulated a lot at his time as a hero of the country, right?
Sadly, the suffering in war is much greater than this clowns can cook and with Raoul conducting the destruction of the country, they won't be able to top Raoul with the suffering they are doing for the ritual. It would be funny if they summon something that is so shet scared of Raoul that it immediately betrays them afterwards.
