So itou junji have been adapting this novel into manga way before furuya usamaru. Idk why he makes it once more, furthermore, they both are a horror mangaka so i can imagine people will comparing them And tbh for me, eventho furuya usamaru have a raw talent and makes some unique artistic choice, his work still lacks a lot compared to itou junji, so for him to adopt this after itou junji, itou's felt far more superior But i see that he makes the adaptation again in 2019 so lets read first
So i spoiled the story because the itou junji one havent reach this far yet I thought it would ended by him killing himself. Now i will read the other version written by furuya still, because the itou junji one is still ongoing
