Become the Strongest Swordsman in Yamato

The old ghost walking in a hurry on the bus, The model running on the school corridor late at night, The bloody hand holding the paper towel from behind while squatting in the toilet, The sound of crying coming from the unmanned piano classroom, The negative stairs quietly appeared at zero o'clock, Crazy cherry blossoms blooming in July... In this era where you would meet one or two ghost friends when you go out for a walk, Chiba Kazuya silently clenched the katana in his hand.
