Delusion Trigger · 空想百科 SoraWiki

CHAOS; HEAD NOAH and CHAOS; The delusional selection system used by CHILD.

Branching mechanism

As the scene progresses, you can choose between positive or negative fantasies, altering the protagonist's imagination and subsequent branches to lead to different endings.

iOS version: Triggering and canceling delusions

When the iOS version of Delusion triggers activation, the screen will show the field of view shrinking toward a circular area. Touch the green area on the left to select positive delusions, and the red area on the right to select negative delusions; Touching areas beyond the two colors allows Takumi to continue the story without delusion.

Maintaining a positive or negative state and pushing the text to a designated position will trigger paranoid rampages, changing scenes, or displaying CG that normally wouldn't be visible along the route.

iOS version: YES/NO selection

The iOS version also offers a YES/NO choice for one interview. After the problem arises, you tap the left and right sides of the screen to make choices, and the story branches accordingly.

NOAH PC Steam Guide: Input and Recycling Arrangements

In this NOAH PC Steam guide, when Delusion is triggered, use LT (keyboard Z) to select Positive Delusion, and use RT (Keyboard C) to select Negative Delusion; If you don't press the delusion button, you won't enter delusion.

The first round of this guide uses Silent Sky as the clear route, while the personal route opens from the second round. The author's recycling plan is to finish Silent Sky first, then restart from START, creating strategy files 01~07 in the common arc; On the 8th, use it separately for negative delusional event recycling, so you can keep the copy established in the first round. Number 08 saved before the 43rd Delusion trigger in Chapter 9; After reading this slot, choose RT for the 43rd and 44th triggers; once the recycle is complete, the game ends.

For sections clearly marked as "No further delusions will enter later," the author suggests turning off the "Cancel skip when delusion triggers" setting and then proceed with read skips.

CHILD Vita Edition Guide: Input and route unlocked

Seiya's "CHAOS;" The CHILD Vita version guide uses the left analog stick input to select the blue positive delusion, and the right analog stick input to select the red negative delusion; If you don't make choices, you won't fall into delusion, nor will you change your color. The Nano and Hua route also has a derivative delusion trigger from the white effect, so the guide reminds you that choices are still needed here.

The guide marks the end of the first round main line as Over Sky End, while the individual route opens from the second round. After completing the endings for Nona, Hinae, Hana, and Haki, the title screen adds TRUE; Select it to enter the TRUE route.
