When he happens to cross paths with her on his way to a bookstore and sees she has a bandage on her face, he knows something must definitely be wrong. Koyomi wants to help her, but Tsubasa assures him that her wound is just something she received at home and that he should not concern himself with it. But when a white cat with no tail is hit and killed by a car, the pair bury the creature and the real trouble begins. When Koyomi later pays a visit to his friend Meme Oshino and recounts the day's events, he is informed what they have buried is actually an apparition, one perfect for Tsubasa in her current state. Tasked with finding his friend to confirm her safety, he discovers that she has attacked her parents, possessed by the "Sawari Neko." Now, it is up to Koyomi to help Tsubasa as she once helped him. ＜＜於是，成為怪異＞＞。未曾开始就已经结束的初恋——羽历。正确与否一开始就不存在。。Golden Week，Golden Love。不让幼女学狗叫的后宫主不是好绅士。黑羽川。叹气。怪异即日常。。 完美的班长，羽川翼。 身为阿良良木历恩人的她 在黄金周的第一天，被一只猫所魅惑了—— 那是，被某人禁止的游戏……人变成兽的物语。 被封印的那「恶梦的九日」，如今终于要展露其身姿了！ 这才是现代的 怪异!怪异!怪异! 这是不知不觉间，坠入其中的初恋。
