User Recommendations for The Summer Hikaru Died

-Similar direction and animation style -Body horror -Both stories, although depressing at times, have quite a lot of heart poured into them. It's not just misery for the sake of misery, there is some catharsis there. -The animator who animated Chainsaw Man ED 9, Masanobu Hiraoka, had an important role in animation for Hikaru -The artists who did OP (Vaundy) and ED (TOOBOE) for Hikaru also did endings for Chainsaw Man (#1 and #4 respectively)
