Mukoku

Kengo Yatabe's mother dies and his father is in a coma. He, like his father, was good at kendo. Those days are long gone and he now lofts around as a security guard and generally wastes time. Meeting the young Tooru Kengo is inspired
Kengo was gifted in Kendo (Japanese martial art) but he quits after a tragic incident. He works as a security guard and spends his days drinking. One day, he encounters a high school student Toru, who has a natural ability in Kendo. Toru revives the spirit of the sport in Kengo and he resumes practice again.
