Chu

Reference the canonical First Playthrough Test (一周目测试) name for the build-specific behavior caveat.
Chu is the mysterious humanoid spirit who contracts with the Returner at the start of Rewinding Cadence. She is the source of the Returner's ability to rewind time and the constant companion across every loop, both in story scenes and in the field as a battle partner.
Chu is described in official material as a humanoid spirit with elf-like features. She is one of the world's spirit-class beings rather than a standard NPC, which is what allows her to grant the time-loop pact in the first place. Public material has been deliberate about leaving her broader nature ambiguous in the lead-up to launch; concrete details about her origin, her faction, and her relationship to the Sunblight Tide have not been published outside trailers and beta builds and should be treated as unconfirmed.
The contract with Chu is the inciting event of the story. In exchange for what the official narrative leaves unstated, she grants the Returner the ability to undo the forty-two-day cycle and try again, and she binds herself to the Returner as both companion and moral counterweight. The pact is what carries memory and certain relationship flags across loops, which is the mechanism that separates the time-loop system from a simple mission restart.
Chu is the protagonist's spirit companion in combat. The duo system pairs the Returner with Chu specifically rather than letting any companion swap into the main slot, and their attacks are choreographed as a coordinated pair: Chu enters during certain skill windows, follows up after specific attacks, and triggers cinematic combination moves on cue. While other playable characters in the game are paired with their own animal-form spirits, the Returner is uniquely paired with Chu.
Beyond combat, Chu drives most of the early-loop dialogue. The announcement trailer's most-quoted line is the Returner's vow to her: "No matter how many times it takes, I will rewrite the world with you." Public footage shows her present in most major story scenes, often initiating exposition that pulls the Returner deeper into the loop's central mysteries. As the wiki gathers verified post-launch material, this article will be expanded with her cultivation track, her unique skills, and her arc across the cycles.
In combat, Chu is treated as the Returner's bonded spirit companion, which means she has her own progression layer alongside the Returner's character growth. Trailer footage shows Chu using a distinct attack set, holding her own animation budget, and triggering combination moves with the Returner that are not available with any other companion. The exact stat block (hit points, scaling damage, ability cooldowns) has not been published and should be treated as Crimson Test build behavior.
Chu's combat role is best understood through combat: she is not a swappable follower, she is the second half of the duo that the Returner forms. Building Chu and building the Returner happen in parallel.
Chu is the in-world reason that progress survives the forty-two-day-cycle reset. The contract she binds with the Returner is what carries memory across loops, and several of the wiki's persistent-state rules are framed in-fiction as "because Chu remembers," rather than as system mechanics in their own right. From the player's side, this means Chu's presence in cutscenes is the visible reminder that the timeline is conditional.
Specific dialogue beats with Chu shift between loops. Some lines are cycle-aware: she remarks that she has heard a certain answer before, or she anticipates a choice the Returner is about to make. This is the most direct in-world signal that the dialogue-system carries memory across cycles.
Some translation passes and community coverage have framed the Returner-Chu relationship as romantic in character. The studio has not formally listed Chu as a romance option in the standard live-service sense (with a unlock chain, gift system, or scene gallery). The relationship as published reads as a deep partnership with romantic undertones rather than as a confirmed romance arc, and this article will be updated if the studio releases a definitive romance-system breakdown that includes Chu.
Her broader nature as a spirit-class being and her place in the world's spirit hierarchy are not yet on-record.
Her relationship to the Sunblight Tide is implied by her foreknowledge of the cycle but has not been spelled out.
Her cultivation track and unique skills as a playable-side companion have not been published in full.
Whether Chu can be developed independently of the Returner, or whether her growth is purely tied to the player character's, has not been confirmed.
All four are expected to be filled in as later beta rounds and the global launch arrive.
