[Fourth Calamity + Player + Boss + Evil God + Loli + White Hair + Invincible + No Couple + Single Status + Game Affects Reality]

My name is Xie Bai, and I've traveled through time.

It seems to be a game world. Am I an NPC, or a hidden boss?

Wait, why am I a sweet, soft, white-haired little girl?!

And what on earth is this Seven Curses Ring?!

"Hey? System! What do you mean Nohara Shinnosuke is a Pillar? What do you mean Uchiha Sasuke is a Pillar? What do you mean the Pillar Men and Hashirama are Pillars? Tailed Beast Jinchuriki? Josuke Higashikata can do that too?!" Lu Li unexpectedly transmigrated into "Demon Slayer" and awakened the Demon Slayer "Pillar" Summoning System! Every three days, Lu Li can randomly draw a "Pillar" and gain all of their abilities. Just as he was excitedly preparing to open the system and use the Pillars' abilities to fight Muzan, Lu Li discovered that the "Pillar" drawn by the system seemed a little different from what he expected. "Hey! System! I can tolerate the previous ones! But system, what the hell is this Optimus Pillar you summoned? Kibutsuji Muzan, huh?! Kokushibo, huh?! Tell my luck!" ...Tentative protagonist's alternate worlds: "Demon Slayer," "Fate/Zero," ...

"I, Xia Xi, am wholeheartedly devoted!"

Xia Xi looked at the large group of girls who had come to her door, and then looked up at the ceiling with a guilty conscience.

"Oh? So you're planning to switch places with the young lady today~"

I'm still planning to trade with the e-sports girl~

Or perhaps... that tsundere from anime? A yandere girl? A cute loli?

Or... as one of the many~

Good heavens! All I wanted to do with the ability to exchange things was become stronger, how did this chaotic situation come about?!
