The Project ERE (Extreme Radiance Explosion) is a secret research project of the Laboratory.
The original objective of the project was simply to research ways to induce sin-induced chain reactions. In the end the research resulted in the development of a new type of weapon, a Sin-powered explosive with the power to turn other Tears into Sin at an incredibly fast rate. The weapon was named by the Laboratory Radiance Bomb and can effectively turn everything in its explosion radius into a sin-covered waste. The bomb can even surpass the protection of the Undying Ones and is supposedly able to destroy their hearth.
The project was proposed and directed by Chana Manvit from 894 ID to 899 ID, when it was discontinued by Tuk-Tuk.
