This extremely dark movie is a revenge story centred around a crime committed in a middle school background. The plot is unsettling as the viewer witnesses a patchwork of criminal acts, toxic behaviours, mental health issues and disturbing scenes. I found the pace of the story really good as the film progresses and the motivations of some of the characters unveil. It might feel a bit over-the-top at some point but it succeed in being frighteningly believable somewhat. I appreciated the ambivalence of the ending and the fact that there is a greyish morale to it...

Acting-wise, the cast was overall pretty good. Matsu Takako is good as this distraught, cold and relentless character seeking revenge. She is a bit over-shadowed by the performances of the three teens actors: given their young ages and the darkness of their scenes, I found them pretty impressive and convincing, even though sometimes their acting might have been a bit too "over-the-top" or uneven.

Production-wise, it manages to showcase the different perspective of the stakeholders in a gripping way. Even the more narrated parts (which are "telling" more than "showing") are captivating to follow due to some inspired mise-en-scene. There was some elements that I felt a bit too exaggerated (in terms of visual effects or for example with the blood spattering...) to the detriment of the poignancy of some of the scenes but it was still super impactful overall. The soundtrack was suitable for the film but not memorable to me.

I would recommend this to people looking for a gripping revenge story, quite different in its narrative style. If you loved manga such as "Teseusu no fune", you might love this as it gives some similar vibe. Given the crime committed as well as the various topics approached in the film, it features heavily (a lot) of really triggering components. I would strongly suggest to look at the tags before watching this if you have any triggers. If you don't, this could be better to go watch it blind in order to not spoil yourself of course.
