Wait guys i saw in chapter 9 "to be continued" so he maybe survive then he somehow get to go in the same hospital where the mc body is (in my imagination mc is just in coma)
also everyone is forgetting that ghost-kun can interact with the world now. he shattered the window, he touched and stopped a baseball bat in ch.9. so why not save tsubaki from a truck lol?
not like they will isekai together
(the raws are at bato .to and dropped nearly a month ago, not sure why ppl talk like it just happened o.o)
Now we know some part of why his memories are sealed.... I mean i think it's brain automatically sealed his memories to protect him from his trauma seing his friends /family died one after another.... This is so sad
