Demon Slayer: How to Turn a Half-Tengu into a Golden Retriever Lolita

(Transformation + darkness + cannibalism + pure evil that cannot be washed away + vastly expanding the world view) Thank you for the invitation. I have just traveled through time, but I was asked to draw a card first... And my luck is like a good one at mining coal in Africa. We directly picked that wrinkled old man... A half-day dog! Help! I don't want to be an ugly old man! Fortunately, the system saw that I was about to shatter on the spot, so it kindly pinched the skin of a lolita with blond hair and red eyes... But why is Mao a lolita! You can make me look like Hate Potian! What the hell? Still can't change it? I really just... Phew... Okay, appearance is justice, so this wave is not a loss. Besides, you can summon joy, anger, sorrow, joy and hatred without losing your head. The system also gives us many new blood ghost skills that we have never seen before. But now it seems there is a small problem... My boss's name is Wuhan! That lousy boss! Ghost Dance Tsuji Mukai! Forget it, forget it, anyway, the system has helped us get rid of Wuxian's control. Um? My doppelganger also changed gender? What about Hupotian? Besides, what should we do in this world? However, as a member of the original novel, I thought about the protagonist group and the pillars who were born hundreds of years ago, and I smiled with a wicked and cheerful smile. … Hey, wait a minute? Why has the plot changed so much? Stop it! You are all OOC! As promised, is there a third party force besides humans and ghosts? Ah? System, please come out and explain it to me! Uh... Night Clan? Monster? Are you sure you made no mistake in appearing in this demon-destroying world? No... No... This world is in complete chaos
