Zanhoshi Reunion

When a Zanhoshi is broken, it breaks spacetime itself, fracturing a single timeline into a tangled multiverse. To repair the Verse, one must undertake the process of Zanhoshi Fusion, until all the disparate swords and timelines are merged. The final fusion in this chain, and the events leading up to it, are known as the Zanhoshi Reunion.

Trivia

 * Only one photograph of a Zanhoshi Reunion in action has ever been captured. It is often mistaken for a humorous painting of dogs playing poker, due to causal anomalies typically present on such occasions.
