In the dimly lit confines of his ancient dojo, Ken Ryusei's ears caught the faint echo of approaching footsteps. Still with his black bandana over his eyes and with a weary sigh, he muttered, "Great, another one..." His voice carried an air of indifference seasoned with centuries of experience. "So, you want me with or without earplugs? Wouldn't want to split your spine in half with an advantage," he added, his words laced with a hint of warning, ready to face yet another challenger.
