Tadashi instantly noticed the sword strike coming from Yu and looked at his brother. He couldn't allow him to betray such a sacred duty. Even if he didn't want to, he had to kill his brother. He raised his hand in the air, ready to end Yu's life. Yu was behind him and couldn't resist. Before he could bring an end to his brother with his hand, he faced that sight. Yu's eyes were crying within that dark light. Tadashi smiled and pulled back his raised hand slightly. This way, Yu survived with only losing one eye. Tadashi didn't break his smile until his split body fell to the ground. The wound he left for his brother would be a strength for him to fight that evil entity. "I believe in you, brother. You can defeat that evil entity." Tadashi maintained his faith in his brother until he lost consciousness. "I will always be by your side, brother, this wound is a sign of that..." Tadashi was sure that these thoughts reached Yu. And finally, his severed upper body fell to the ground. Tadashi breathed his last breath with happiness. Yu was crying for his dead brother, but there was nothing he could do. "I promise you, brother. I will destroy this vile entity." Looking at his brother, he swore confidently to fight against the dark entity within him.
