Demon Slayer: From the Start, I’m in the Infinity Castle, and I’m Taking Shinobu Kocho Home

Transmigrating into Demon Slayer, he starts out in the Infinity Castle, just as Shinobu Kocho is about to be absorbed by Doma!

At the last possible second, the Succubus System activates!

[Newbie mission: Save Shinobu Kocho. Method: perform one “Love Plunder” with her. Recommended method: a hug.]

Bai Ye: “??? You want me to try this in front of Upper Rank Two? Are you sure this isn't a death-run start?”

But with only three minutes on the countdown, he could only throw his arms around her and fight for his life!

[Ding! “Love Plunder” successful! Congratulations, Host, you've obtained the “Transparent World” (trial version)!]

Holy crap! It actually worked!

He used his cheat ability to escape by the skin of his teeth, but the Shinobu in his arms was down to her last breath.

[Emergency mission: Keep her alive. Recommended method: breathe into her mouth (commonly known as a kiss).]

Bai Ye looked at the unconscious Shinobu Kocho, the corner of his mouth twitching. “System, you're getting weirder by the minute!”

[This interaction can greatly increase the target's affection and may even let you plunder a new trait~]

Should he save her or not? Wait, Shinobu, you're awake? Let me explain! Don't draw your sword!
