Day of the Rift (DOTR)

Day of the Rift, often referred to as DOTR or “Portal Day,” marks the extraordinary event when portals appeared worldwide, connecting Earth to another realm. Different groups have various names for DOTR; notably, inhabitants of the other world, especially the monster girls, refer to it as the “Day of the Romance.”

This event introduced a new energy, known as “mana,” which permeated our planet. Along with this influx of mana, monster girls began to emerge on Earth, and simultaneously, human females started transforming into monster girls.

The entire event unfolded rapidly, spanning just seven days, and due to its chaotic nature, many details remain undocumented or lack sufficient evidence for verification. However, the main incidents of DOTR can be summarized into eight key events, occurring from Day 0 to Day 7. Please refer to the following official record to learn more about the occurrences of DOTR.
