No actual vomiting in episodes 1-3 although there is spitting blood - mostly in the 3rd episode. when they are being beat up in the virtual world. as an emetophobe it didnt trigger me severely, but if you do get disgusted by spitting blood you can skip the scenes where they get punched <3
for a moment near the end, it appears as though eyes may be harmed but it is okay in the end, however eyes are forced open and whilst it would bother some people who hate eyes, it won’t bother others
During episode 2, three boys are on a laptop attempting to leak Nanno in her underwear with hidden cameras, however instead they find Nanno with a p***s Spoiler: (it’s not hers) however the boys make derogatory comments, calling her disgusting and spitting on the floor. Can be triggering for trans women watching the episode.
This is something that happens in this whole series: sometimes justice is done and you as a viewer feel satisfied; sometimes it leaves the viewer feeling sickened.
