This is going to be fast. Gakkou Gurashi! is an amazing anime that is really really hard not to spoil so I’m going to be quite vague about this.
Basically, Gakkou Gurashi! is tagged as horror and drama but I would tag it as dark themed drama as it is bloody but not gory and not scary. The story is amazing and the reveal will make you fall from your chair. The story is very good and interesting. Visually, this anime is great.
If you want to watch an amazing dark themed anime then go ahead but I have to say the first episode is a really big lie. If you find yourself asking why you are watching this and wondering where is the dark theme, you’ll need to go trough the first episode to find it 😉
