To Dragon's Blade - Well, spirit energy is a good primary source, but those untalented in the arts of magic will have problems. Demonic energy is quite powerful, but can infect and spread a little too fast (And if I'm right, we're trying to minimize usage, right? I mean, we're still trying to preserve human realms, after all.)

Allow me to present some advantages and disadvantages of the energy I presented:

One of the advantages is that the more evolved a human/monster is, the more powerful it gets. And if a normal human man turns into an incubus or when a human woman gets transformed into a monster, their genes would "evolve" of some sort, increasing the power of evolution. Another one is that it doesn't require extensive knowledge or training to use, but simply needs one's fighting spirit in order for it to be triggered, and can be mixed to fortify and empower magic or give a powerful (albeit temporary) boosts to our weapons. It can also be melded with spirit or demonic energy.

The disadvantages are: The effects are temporary, and all the power boosts will automatically disappear after battle, or can even be lost in the middle of the fight should the fighting spirit of the user would wither down with fear. Another one is that our enemies will have access to it as well.

Although, there's this one feature that is the best out of all its uses: With enough fighting spirit, one can kick logic to the curb and do the impossible! In short, defy logic itself.

Shouldn't we present this to the demon lord, or at least, Deruella?
