Believe in Yourself (己を鼓舞せよ Onore o kobu seyo?) is the third volume of Kimetsu no Yaiba.



Tanjiro and Nezuko cross paths with two powerful demons who fight with magical weapons. Even help from Tamayo and Yushiro may not be enough to defeat these demons who claim to belong to the Twelve Kizuki that directly serve Kibutsuji, the demon responsible for all of Tanjiro's woes! But if these demons can be defeated, what secrets can they reveal about Kibutsuji?[6]

Author's Comment

Hi, I'm Gotouge. Volume 3 is finally out! And it's thanks to me relying on a lot of people, getting help and receiving encouragement. Thank you. Even I'm shocked. I'm the type who jumps to the conclusion that things are sure to fail, but if I offer my cowardly self tasty bananas and other treats, and tell myself that maybe there's still hope, I'll keep doing my very best.
