Quick answer

DRAGON’S DISCIPLINE is the scenario added in version 1.0.0, and the official wording places it between the true ending and the 25 TRUE endings. The 1.0.0 patch notes say the scenario unlocks when six or more characters have each unlocked at least one Fragment of Space-Time, and that 25 TRUE endings unlock after DRAGON’S DISCIPLINE is cleared.

The official sources never spell out how the singular “true ending” and the 25 TRUE endings relate to each other, and no official list, condition table or route chart exists. Community records suggest the scenario has branches of its own, but treat those as leads rather than steps.

What unlocks DRAGON’S DISCIPLINE

The 1.0.0 patch notes give the concrete condition: once six or more characters have each unlocked at least one Fragment of Space-Time, an unlock event for the scenario fires. Pre-release coverage described the same thing more loosely — “after progressing through DAYS OF TORNADO to a certain point” — because that press text was written in August, before the release notes existed. Where the two differ, the September patch note is the more specific and later record.

The developer also frames the scale of the new scenario: more than roughly 60,000 characters of new text, with the existing DAYS OF TORNADO described as the “first half” of the game and DRAGON’S DISCIPLINE as the second.

Fragments of Space-Time themselves are the part the material does not explain. None of the sources checked here documents how they are earned, so this page cannot tell you the fastest way to collect them — only what the unlock condition counts.

“True ending” and “25 TRUE endings” are two different statements

Pre-release coverage quoted the publisher saying the new mode leads to the game’s “true ending”, singular. The 1.0.0 patch notes then announce 25 TRUE endings, plural, unlocked by clearing that same scenario. Both statements are official; their relationship is not.

One practical detail comes from the game’s own interface. The Story Selection screen shown in the official store screenshots carries a note that DAYS OF TORNADO level 2 and above become available after the true ending is cleared — so the true-ending route also gates higher difficulty levels of the earlier scenario.

What is known about the scenario’s own endings

Two YouTube uploads from late September 2026 label DRAGON’S DISCIPLINE clips with ending names — “Researcher Ending” and “Moon’s Cooperation”. They suggest the scenario contains branches of its own rather than a single straight line, but video titles are weak evidence: neither clip states where it sits in the official ending structure, and no text source checked here confirms either label.

The Korean community record adds a third formulation, describing a “happy ending route” that opens after seeing endings a certain number of times. That phrase does not appear in the official patch notes, so it stays community vocabulary until an official source uses it.

The community-documented hidden ending

The most concrete community answer is a hidden ending tied to Octanya, the boss of the deserted-island training event. A Japanese guide author and a Steam discussion post describe the same chain: during island training, choose the forest route, continue to the waterfall, and let the dragon girl eat the sealed shrine; Octanya then appears and drops the skill Call the Storm. Using that skill to its maximum level — nine activations in one battle — triggers an ending and unlocks the related achievements.

Three community sources agree on the trigger and none of them is official. It is also not established whether this ending counts inside the official 25. Keep the steps as a documented community route, not as an official requirement.

Patch status and what to re-check

Version 1.0.1 added the ability to save before a TRUE ending, which matters if you plan to test branches yourself. The same release fixed a final-boss retry problem, and 1.0.2 followed on 28 September. Everything above was checked against sources dated up to 29 September 2026, three to five days after release, so re-check the patch notes before you commit to a long route.

If you only need the ending set as a whole, the endings page covers the version split between the five Early Access endings and the 1.0 structure. This page stays with the scenario and the TRUE-ending question.
