It’s enticing in the beginning; wanna see some gore and be fascinated? Sure, read like 20-15 chapters.
But afterwards, it lost some of its charm and became a bland generic story, (sarcasm) woah rape and just killing hundreds of people again in the middle of the street, so interesting. Woah mc heroine gets shotgunned and stabbed, oh yup, she’s totally fine. Next chapter, she’ll kill another group of people.
Japanese people like rape too much. It becomes morally wrong and boring (like really?!) to use it constantly just for readers to hate the characters.
