Demon Slayer: the Resurrection of Mukai

Because the Demon Slayer Squad is too tired to kill ghosts at night Nothing to do during the day! On an uninhabited desert island, a scientist carefully researched and created a kind of ghost that is not afraid of the sun, making up for the vacancy when the Ghost Slayer Team cannot kill ghosts during the day. (The scientist has been arrested and is being interrogated by Zusanzhu) However, ghosts who are not afraid of the sun have spread everywhere! In desperation, the three pillars could only train a group of ghost killing teams to kill ghosts during the day. The unjust ghost killing team began their hard-working career of killing ghosts again.
