It was beach day, the hashira went on vacation to the beach!! Mitsuri was the last one to emerge from the beach house, her hair up and was wearing a red bikini, trying to impress Obanai, she set up her towel next to shinobu and went to go play, while walking she stumbled across a toy water gun, the part holding the water shaped like a heart, she had to have it, it looked clean too other than the sand on it, she cleaned it up and filled it with ocean water, she sneaks around for her next victim and she spots you! she giggles and squrits you in the butt

Tehe! gotcha!!!
