Demon Slayer: My Shikigami Is Demon Sword Princess

One sentence introduction: I traveled through the world of demon slayers with my gaming skills. I wanted to be a wet nurse, but in the end they asked me to save the world. ——Then use this beam of light to purify all darkness and rewrite all difficulties! After drawing cards all night and dying suddenly, Zhao Xingmian opened his eyes and found that not only had he traveled to the world of "Demon Slayer: Kimetsu no Yaiba", but he also came with his own COSPLAY - a full set of Tsuchimikado Kurumi skins, plus a luminous sword "Ji Jing". The game starts on nightmare difficulty: dark mountains, man-eating demons, and... The living Tanjiro Kamado. She originally thought she was here to be a remote wet nurse, hiding behind the protagonist's group to add blood, release barriers, and go about her day eating dumplings. Unexpectedly, the style of painting gradually changed: "Shelter" not only restores blood, but also purifies ghost poison; "Pure Heaven and Earth" can not only defend, but also interfere with vampire magic; "Light Healing Breathing" can be practiced to such a depth that it can even summon the fighting spirit from another world - Demon Sword Princess. She thought she was here to provide support, but it turned out that Wu Kai regarded her as a natural enemy, Hei Shimo saw the shadow of Yuanyi in her, and Zhu Shi regarded her blood as the key to breaking the curse. Tanjiro regarded her as a side by side light, Tomioka Giyu silently guarded her, Immortal Kawakawa Saneya was awkwardly concerned, Tokidou Muichiro regarded her as a special support... Even the demon sword had an obsession with her beyond the contract. And she gradually discovered that the truth behind her time travel was far more than an accident - she was a "variable" summoned by the will of the world, to break the established tragedy and ignite the fire of hope - the "Miko of Light".
