Non-Everyday Life in a Crossover World

Because of her special ability (was it really because of her ability?), Saotome Yui runs away from home and goes to Ikebukuro alone. There, she meets the legendary Headless Rider, as well as the Dollars, the Slasher, the Yellow Scarves, and others, and a series of extraordinary events begins. Reading guide: 1. I'm no good at writing blurbs; this is a crossover. 2. The ending is an NP, no explanation needed. ╮ (╯_╰)╭ 3. Original female protagonist; the canon heroines aren't bashed. 4. It may be Mary Sue-ish, so beware. If you choose to read it, bring your own hazard warnings, or click X.
