Directed by Kenta Fukasaku, the son of Battle Royale director Kinji Fukasaku, this movie starts with a girl named Asuka wearing a rat mask and committing suicide by leaping off the roof of her school. 49 days later, a note brings her classmates together to be confronted by what seems to be her ghost.

But who does the mask belong to? Can it belong to more than one person? And will any of the students survive to see the next school bell?

I have to say, I’ve never seen a more adorable killer, a girl who loved to smile and who now leaves stickers and smiley faces on her revenge notes. Also, killing someone who doesn’t get a perfect score in karaoke is totally the modus operandi of a Japanese schoolgirl slasher.

It’s only 76 minutes long, which if you ask me, is the perfect length for a movie like this. Also, more scooters should blow up in films.

You can watch this on Tubi.
