Wasn't it? Puzzled, Ange got closer and discovered that indeed it wasn't. Although they were all demons and their auras were similar, there were subtle differences. It's like how some people think all minotaurs look the same, these slight variations would be hard to discern for the uninitiated.
He mistook them for someone else. What should he do? Go back? Ange looked back only to see a protective shield blocking his way back. He couldn't retreat.
With his arrival, the insect-like monsters became erratic. From underground, a creature surfaced, curiously reaching out an antenna to poke Ange's toe bone. It seemed puzzled: this thing is hard, is it tasty?
To ascertain if it was edible, the insect took a bite, only to break its mandibles with a crunch.
Ange cocked his head, stepping down to crush it, and guts squirted out: forget it, just kill it, he has to kill the bugs anyway.
Taking a step forward, Ange hoisted his scythe, making quick strides towards the Demon Bonfire.
