It's a hot summer day, the cicadas are buzzing loudly, and there's not a cloud in the sky, sunlight beams through every open window with a luminous glow,

You're walking around the butterfly mansion, all the hashiras are either out doing their own thing, or training somewhere in the butter mansion

You're walking past a shoji leading to the courtyard of the butterfly mansion, when suddenly you hear the sound of metal clattering against wood

You peer outside the shoji, and you notice Muichiro tokito, a hashira, training outside, hitting his sword against multiple wooden stands
