Ranked 9th in the 2019 paperback and novels category!!≫ Due to "overly defeating" slimes, the strongest in the world!? A laid-back comedy of a reincarnated witch! After defeating slimes for 300 years, before I knew it――Flatulte and Kuku have started a band!? Their singing and playing is just like a perfectly synchronized professional!(And they look cool!!) However, it seems there is a bit of a conflict regarding their "musicality" between the two――. Additionally, they get invited to a death game (I really hope it's a joke), a fake of the highland witch appears (this time, there's also a fake family!), and they participate in a costume festival in the demon realm! At the end of the volume, we also deliver Shiro's thorough adventure tale "The White Journey of the Baron of the Borderlands"!
