Kokushibo felt jealousy toward Yoriichi once again. While Yoriichi was alive, he had never surpassed him in anything. He had never imagined that even after Yoriichi's death, he would still suffer another crushing setback because of him.
He had failed to notice their mother's illness, but Yoriichi had known about it long before and had stayed by her side, caring for her. Unaware of this at the time, he had thought Yoriichi was merely clinging to their mother and seeking her affection. Only after their mother died and Yoriichi left, when he read her diary, had he learned the truth.
As for talent and strength, there was no comparison. At just seven years old, without ever receiving instruction, Yoriichi had easily defeated the teacher who was teaching him swordsmanship. Even after training until his palms bled and grew thick calluses, he had never managed to land a single blow on that man, yet Yoriichi had defeated him effortlessly.
Now, even after Yoriichi had died and the Tsugikuni name itself had vanished into the river of time, people still spoke his name.
"Even after your body has completely rotted away... you are still so exceptional that I cannot help envying you..."
Jealousy flared in his heart, and all the humiliation Yoriichi had brought him surged back.
Chiba Yo sensed that something was wrong with the demon facing him and placed his right hand on his sword hilt. Whatever happened, he would be able to strike as quickly as possible.
Though jealous, Kokushibo knew Yoriichi had long since died, and he soon regained his composure.
"Yoriichi Tsugikuni... was my younger twin brother when I was human..."
Kokushibo answered Chiba Yo's question.
Though he had already suspected as much, Kokushibo's answer still shocked Chiba Yo.
Two brothers: one had become a powerful swordsman
