<p>I saw the live action film, and found out that it was based on a manga, so I figured I would ask here.</p>
<p>Does anyone have a complete list of all the triggers? I know <em>crying, acting violent, reading comics, using phones, drinking from bottles, staring too long at someone, leaving school grounds, beer showers, non authorized clothing, having 7 people pointing at you all at once, touching sexually stimulated parts, and staying at school until dawn</em> are all triggers for suicide, at least in the film, maybe not on the manga.</p>
<p>Please share the rest if they are known.</p>

Having read the series and editing the community wiki I think this is as complete of a list as there is for the manga, although signals 34-50 were never revealed and signals 86-88 despite being shown were too difficult to make out and my Japanese isn't good enough to inference what they could be

I saw the live action film, and found out that it was based on a manga, so I figured I would ask here.

Does anyone have a complete list of all the triggers? I know *crying, acting violent, reading comics, using phones, drinking from bottles, staring too long at someone, leaving school grounds, beer showers, non authorized clothing, having 7 people pointing at you all at once, touching sexually stimulated parts, and staying at school until dawn* are all triggers for suicide, at least in the film, maybe not on the manga.

Please share the rest if they are known.
