The Storekeeper was a storekeeper of the place Hiroshi lived in. He is seen at the start of Version 3 and the end of Version 6, in both he is seen running to the front door trying to escape, he hears the Oni, in fear he tries to kick the door down. The Oni then appears and eats him while he screams.
His sprite is the "148-Storekeeper02", a default RPGXP character. He seems to be an old and slightly obese man wearing blue and brown clothes.
