One More

I hoped to avoid this situation at all costs.

I didn't want to use the demonic powers once again, and that was also the case when my classmates and seniors were not so far away. But this was a moment where pretense no longer served a purpose. As the assassins closed in, I reached deep within myself, touching that dark, familiar power I'd kept locked away for so long. The reaction was immediate and violent.

"What's he doing?" one of the assassins muttered, sensing the sudden shift in essence pressure. "This... this isn't normal enhancement..."

Most of the assassins who were on us were of Priest rank, while I couldn't quite tell what level the woman was at, maybe she was Knight? I didn't know - anyway - being in Preist rank they could feel the essence that I was hiding welling up from my soul sea.

My blood felt like liquid fire in my veins as the transformation began. 

That's right!
