Back at his usual spot, Rin pulled out both beast cores from his pouch. He held them in his hands, heart pounding.
"…Alright. Let's do this."
As soon as he focused his intent, the cores glowed faintly. A sudden chime echoed in his mind.
[System Notification]Beast Space and Evolution System unlocked.+2 Beast Cores consumed.Beast Space Rank: ENew Features Unlocked.
His body trembled. He clenched his fists — and felt it.
Strength.
His limbs felt lighter, tighter. His senses sharpened."...My strength—it just doubled."
He opened the status window again.
[Player: Rin]• Beast Space Rank: E• Capacity: 1/3• Environment: Selectable• Core Storage: 0• System Functionality: Active
A new tab blinked open: [Beast Environment: Choose habitat for your beast]
"Huh? A place for Rakka?"
Rin rubbed his chin."He's a rat… Beast type. Feels like a cave would suit him."
He selected it.
In the blink of an eye, the Beast Space visual changed. From blank void to a small dark cave, just big enough for a small creature to move around.
"It's tiny… but still better than that F-rank box."
He smirked. "Alright, Rakka. Time to live like a real beast."
He summoned the rat, who squeaked in confusion."Don't worry, little guy. You're getting an upgrade."
With a thought, Rin stored him into the beast space.
A new pop-up appeared.

Rin's eyes widened."Wait… He can evolve?"
He stared at the floating screen again.
"From F-rank to E-rank in a week… Just by feeding him?"
He sat back and let out a whistle.
"This is nuts… This system's no joke."
He chuckled, eyes full of hunger — not for food, but growth.
"Let's see how far we can go."
