Demon Slayer: Become the Disciple of Koizhu at the Beginning

"Multiple heroines + system + no brainlessness" Traveling through the world of demon slayers, Natsume Yuuma awakens her [posterior] physique, and her style of painting completely collapses! Others' breathing methods rely on practice, but his breathing methods rely on... "Sticking"? Meeting Nezuko for the first time: "This girl smells so good! Ten-star potential? Bring it to you!" (Keep an eye on the box. Jpg) Encounter with Zhu Shi: "The doctor's sister's healing blood is cold and warm at the same time. I have to taste it deeply!" Dealing with the Butterfly Ninja: "Senior Sister, you want to use poison to torture me? What a coincidence, I just need your "Wisteria Poison Charm" to temper my body!" Learned from Ganlu Temple: "Master's love is as sweet as cherry cake? I can absorb this surging 'Sakura Honey Soul'!" Fierce battle in Flower Street: "The jealous ghost honey of the Shangxian Land? The extreme emotions of the twin ghosts? They are all my nourishment!" This is a story of a journey through the Demon Slayer World... Ah no, a journey of "emotional resonance", soaring to the ceiling in strength, causing all the original characters to completely break their defenses and doubt their lives.
