Be a Support in Demon Slayer: Kimetsu No Yaiba? Mistakenly

Others dress up as Demon Slayers and work as swordsmen, while I dress up as Demon Slayers and work as a logistics officer. The tasks issued by the system are more and more outrageous: "Stop Yiwozao from saying the line "Let's become a ghost." "Install 500 wisteria air fresheners in Infinite City" "Make Tomioka Giyu laugh once (reward: introduction to psychology)" I relied on modern knowledge to kill the plot, and the eyes of the pillars looked at me from suspicion to shock. When the final battle ended, the system asked: "Leave the memory behind, or leave the person behind and forget everything?" I chose the latter.
