In a certain town, a peculiar gothic-lolita boutique called LAST WEDNESDAY opens only on Wednesday nights. Risa, the sheltered granddaughter of the building’s owner, takes on a part‑time job there and soon discovers that the shop’s proprietor is actually a vampire named Wednesday. Wednesday is a cute, naive vampire with little knowledge of the outside world, while Risa is an innocent high‑school girl from a well‑to‑do family. Together they run the odd little store, assisted by a cast of eccentric regular customers who drop in every Wednesday. The story unfolds as a gentle, slice‑of‑life four‑panel comedy that follows the pair’s daily interactions, the gradual deepening of their bond, and the arrival of new friends who brighten the nocturnal hours. As the two grow closer, irreplaceable feelings begin to take root, and the dark Wednesday nights take on a warm, sparkling quality.
