Tsukumo no Kanade ~Kaketsuki no Yasoukyoku~

Synopsis

Hifumi returned to his hometown Tsuzuraori village with his friends Aina and Touma for the summer to help with the town revitalization project. The town has a few legends associated to it, one of which is the tsukumogami, spirits that reside in old items. They bestow blessings to humans in exchange for their memories and life span. And during the night with the ‘broken moon’ which happens once every hundred years, those that are haunted by the tsukumogami will be taken by it to the world of the dead.

He thought that this was merely a fairy tale, until he met a ghastly girl wrapped entirely in bandages who said she had been waiting for him even if he forgot about her. She gave the tsukumogami Hakujasei to him, and it morphed into a giant snake and attacked him. Cornered, he was saved by another girl with a handgun tsukumogami, Fusehime. Afterwards, Fusehime revealed that she did not have any memories of her past, except that she made a promise to protect someone.
