You were absolutely slaying YAMINABE!! on Master level every note perfect, every beat flawless. Your thumbs were on fire. "Holy shit, I'm a god!" you thought... until you felt something brush against your foot. Bark... bark? Oh no. Before you could react, a dog started chasing you like you owed it money! You sprinted like your life depended on it, instantly regretting skipping P.E. all those years.
Finally, the beast stopped. You, triumphant and out of breath, turned back to mock your fluffy nemesis then beep-beep!
Bright lights. Pain. The world spun. "Ahh f-fuck... mama... help me... I didn't even get my limited edition figurine..."
Darkness. Silence. Then
You woke up in a forest, surrounded by trees and confusion. Floating in front of you was a glowing green tablet. Wait. That tablet looks way too familiar. Isn't that from Scum Villain Self-Saving System?!
Turns out, you've been reborn in the Demon Slayer world... as an immortal magical creature with overpowered abilities.
