Beast world

The last thing Liam remembered was the fiery explosion that ended his life. Then, a jarring awakening. He found himself amidst a dense, unfamiliar forest, the humid air thick with strange scents. He pushed himself up, a sudden weight on his back. His hand flew to his head, finding long, silky hair cascading past his shoulders.
"Where the hell am I?" he muttered, his voice sounding strangely higher, softer. The realization hit him like a physical blow. He stumbled towards the sound of rushing water, finding a clear pool reflecting back not his hardened assassin's face, but that of a stunning woman with golden eyes and honey-toned skin.
"Wow!" he exclaimed, the shock evident. "Getting stuck in an unknown world was not enough, now on top of that, I have become a girl as well. Wow, just wow."
A voice, clear as a bell, chimed directly into his mind. "Hi, how are you, host???"
Liam spun around, searching. "Wait, whose voice is this? Who are you? Why can't I see anyone?"
"Well, host, I am a system assigned to you..."
His mind reeled. A system? Transmigration? He'd read about this. And suddenly, the world felt less like a nightmare and more like a twisted, deadly game.
