Investigate the history of Section 1

The First Investigation Division of the Shamitsubu Police Security Bureau in 'Past Guys I/II' has already been disbanded, and 'ZERO -prologue-' returns to the previous two years to investigate what happened in this organization. "Div1" continues to unfold along the world established in the prologue, but the main cast includes new characters who did not appear in previous works.

Consciousness and language

The author lists the arbitrariness of consciousness and unconsciousness, neurons, and linguistic symbols as the main themes of this piece. The work attempts to present the spiritual world of the imagined or created, discussing the reality of the characters through discontinuous time and space and cognition; This belongs to the narrative experiment and thematic setting of the work.

Sections and publication methods

The official team classified this story as a roughly three-hour digital novel and offered a Windows version. Div1 is one part of ZERO's journey toward its conclusion and cannot be directly regarded as the final version of the entire ZERO series. The author's publication page also indicates violent elements; If the age disclosures differ between the official website and the publishing platform, the source scope should be kept separately.

The boundary between the prologue and Div1

In the prologue, Watanabe, Madara Neko, and Shigemura belong to the prehistory of Investigation Section One. Div1's release notes emphasize that the main characters are new characters who have not appeared before, so the partnership in the prologue does not directly serve as part of the Div1 character list.

Windows 2022 section

Div1 was released on November 9, 2022, with download file labeled 1.00. The release page lists Windows 7 64-bit, Windows 8 and 10 32/64 bit, and Windows 11, with subject indications showing brute force.

The relationship between the same series

I/II, the 2016 ZERO prologue, and the 2022 Div1 are part of the K2Cee catalogue entries. The prologue returns to two years before I, and Div1 continues from after the prologue; The release order and the chronological order within the story are recorded separately.

Musical variations on the title screen

This installment uses a title screen mechanism not previously seen in the series, featuring different arrangements familiar with the title music. K2Cee's Div1 original soundtrack includes all variations of the title, with music and arrangement credited to G9Fried.
