Demon Slayer: Kimetsu no Yaiba Vol. 13: Transitions
The strange shape-shifting demons Hatengu and Gyokko attack Tanjiro and his friends in the hidden village of swordsmiths. The Mist Hashira, Muichiro Tokito, engages the demons, but he'll need some help from Tanjiro and another Demon Slayer, Genya. It's bad enough that they have to fight two upper-rank demons, but can they handle a foe who can split itself into four separate bodies and regenerate almost instantly?
