I just realized this image (MANGA STUFF) kinda has spoilers with Satoko's eye colors being different.
As a manga reader I would also recommend it's probably best to drop the anime if the deaths are too much. IMO the next episode is probably gonna be the worst and after that happened in the manga I just got desensitized. Tho so far what BreadBunny said about characters surviving their introductory chapter has been true so far... (MANGA STUFF) which doesn't stop from me getting worried about Marin's sister
