Detonator

Detonators, also known as Surge Arms, are a series of weapons made by Relius Clover that use Artificial Causality Phenomenon Weapons as their base. Seemingly, they are almost identical to Phenomenon Weapons themselves; however, Relius has augmented them, so their true powers remain unknown, but it has been stated that they can, keep up, and even beat, Nox Nyctores such as the Deus Machina: Nirvana.

The only known Detonator is Fluctus Redactum: Ignis; however, at least 4 other different Detonators, including prototypes, are known to exist.

According to Makoto's bad ending in Continuum Shift Extend, her Soul is more than enough material for the Detonator. The conversation between Relius and Makoto revealed that Clover needs some sort of fulcrum in order to topple the soul and reshape it however he wants. In her case, her bond with Tsubaki Yayoi was the key to her soul.
