Demon Slayer: Succubus Physique, They Throw Themselves at Me from the Start!

[Multiple heroines] [System-based] [Succubus physique] [Invincible] Overworked salaryman Uesugi Toru accidentally clicks a strange pop-up. When he opens his eyes again, he has fallen into the blood-red mountains of the Demon Slayer world! Hunted by demons from the very start and on the brink of death, everyone thinks he’s about to become their next meal. But he only sneers, and a dual cultivation System binds itself to him on the spot! All he has to do is win the favor of high-fortune female characters to rack up points, exchange them for divine skills, and master every Breathing Style. The effort is minimal, the rewards are absurd! Starting at the Butterfly Mansion, he steps into a romantic battlefield and onto the path to invincibility! The Flower Hashira saves him with tender care, the Insect Hashira acts tough while losing her composure, Kanao makes her first choice for his sake, and the Love Hashira blushes bright red for him! Yesterday, he was just an ordinary man who had stumbled into the demon world. Today, he’s a peerless prodigy who draws a crimson Nichirin Blade to slay Lower Ranks, uses the Transparent World to break through every technique, and burns demons to ash with Sun Breathing! Rui? One slash! Upper Ranks? He kills them too! Muzan is enraged, the Hashira are stunned, and the entire Demon Slayer Corps is beginning to realize that this man is rewriting everyone’s fate!
