  • Conversion is instantaneous closer to her; the further away, the slower the conversion.
  • Effective range is about 1km.

Intro

The setting is modern-day Tokyo. Due to human indolence, the Great Barrier protecting Tokyo has warped, blurring the boundary between this world and the next, allowing Yokai to manifest. One day, it is discovered that the control core (Spirit Stone) managing the ley lines will appear in a few days.
The appearance location is Chiyoda Ward, Tokyo. Whoever obtains the Spirit Stone will rule Tokyo for the next thousand years. A territorial war between two factions of Yokai, divided into the Ueno side and the Shibuya side, was about to begin.

Yokai are so fascinating, aren't they? My favorite is the Azukiarai.
