Opening the Kunikida Brothers with the Kamado Siblings' Approach

The entire Kuni family was slaughtered by demons in a single night. When Yoriichi returned from gathering firewood, Sanemi, who had turned into a demon, was the only survivor in the family.

And so, carrying Sanemi on his back, Yoriichi set off on the path of demon slaying, determined to turn his brother back and avenge his parents (crossed out) mother!

This will be over soon. As soon as the scumbag boss is found, he's dead for sure.

Please note that this is set in the Taisho era.
