Shadow Immortal

"What?!"

"This is different from what Mira and Aiden did!"

The class gasped in horror as the once-normal bullfrog transformed into something unrecognizable. It didn't just turn dark like it should be after receiving the curse.

Instead, its body was now a terrifying mass of pulsating, uneven growths of muscle or flesh. Indeed, it no longer resembled a frog but a distorted, quivering lump of flesh.

"This…" Armin froze, his hand still outstretched, but his face was already pale.

"What… what happened?" he muttered, his voice was barely audible. He didn't do anything else aside from following the instructions. There shouldn't be any problem at all!

"Return to your seats…" Professor Darion Vex said as he activated the classroom's formation art to seal the frog that acted differently.

Based on his observations, Armin followed everything, and there shouldn't be any mistake. At the very least, it wasn't something he was able to detect.
