Assistance System Starting from Demon Slayer

A young boy wanders into the world of demon slayers, and the first mission of the awakening system is to prevent Tsujimu Oniitsuji from annihilating the Kamado clan. How could I, an ordinary person, do such a good job? Fortunately, the system gave me a novice gift pack and tasks. "Ding! Released gift pack for newbies: Burning Fruit Ability for one hour, three-color domineering for beginners" "Ding! Mission released: Prevent Oniitsuji Mu from killing the Kamado clan" "Reward: lv.5 Vector control requires the host to develop its own power" PS: You don't need to use your brain when reading this, because this book is mindless and enjoyable. It's just enjoyable. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
