[What is NECLOGOS?]

Project 'NECLOGOS'

The 'Necros' project. The words of the dead. An initiative to pin lost people, things, and events caused by incidents into the present world.

The Public Relations Department has adopted 'music' as a means to accomplish this mission. Inevitably, elements that 'cannot be resolved by merely arresting culprits or solving cases' fall through the cracks. To collect individual circumstances, motives, and the 'emotions' embedded in crimes, re-present them to the world, and mourn what has been lost, the department uses sound and poetry.

This is Project 'NECLOGOS.'

Today, this activity is considered the most important task of the Public Relations Department.

'NECLOGOS'

The four-member core of Project 'NECLOGOS.' A four-member music unit formed by Yem, Kuremu, Ere, and Rei, all belonging to NEST Public Relations. Real names, ages, and other personal details are undisclosed. All members possess the special ability 'Seven Voices,' embodying the 'seven-colored voice,' capable of reproducing almost every human 'voice' regardless of gender, age, or hierarchy.
