3 Nen A Gumi: Ima kara Mina-san wa, Hitojichi Desu (2019)

The plot is very similar, about a group of students who is locked up in school and need to solve the quiz to be able to survive

- Both are in a high school setting
- Both talk about bullying
- Both have teachers trying to change their students for the better
- Both are mystery and thriller

They are pretty different, but at the same time they have some things similar.
They deal with bullying and I should also say "surviving". In 3 nen students are blocked in a classroom with their teacher, while in Limit students who survived after an accident are all alone in a forest (between them there is also a killer). In both there is police the who need to rescue them and save them. Both are psychological, full of twist and secrets.

It also talks about the investigation of a boy, who's always bullied in school. One day, after he left the school, he was mysteriously murdered. it was full of thrill when u watch this!

Similarities:
-The female leads are played by the same actress in both 3 Nen a Gumi and Mask Ward
-Both stories are centered around a hostage situation gone wrong.
-Both stories have a theme of revenge and justice.
-Both deal with controversial topics
Differences:
-3 Nen a Gumi takes place in a classroom, and Mask Ward takes place in a mental institution/nursing home.
- 3 Nen a Gumi is about the suicide of a classmate meanwhile Mask Ward deals with corruption inside the institution.
- 3 Nen A Gumi deals with the corruption in society whereas Mask Ward deals with political and medical corruption.
I recommend both the drama and film if you enjoy a good mystery and psychological thriller.

- Thriller / Mystery
- School isolated from the outside world with students having to manage on their own

Basically the mcs are teachers that are trying to teach some morals and new mindsets to their students so as to help them not become pieces of trash later on. One of course tries to teach them in more extreme ways than the other. Both drama address heavy societal topics and deliver strong messages.

Instead of student the teacher is trying to change the students way of think, same kind of feel with the setting and thriller

I recommend this both drama because , Male lead and Female lead
try to solve problem
In one drama explosion and another student murder/suicide

Both psychological drama involving teacher and students. It's just that suzuki sensei can be the "I'lll shove my ideals down to your throat" type of drama.

Student have to solve the puzzle to reveal the truth about their school. There's an episode about finding out the death of an old student to complete the exam.

Both involved high school students and the teacher. The teacher trying to find out something from the students. Well act and plot

The idea of pitting student vs. student, instead of a government plan as a individual in charge of a hostage situation. Similar atmosphere between both sets of students.

A similar situation where a group of students is being manipulated by a larger power; 3-nen being manipulated by their teacher and Zankokuna by the unforgiving net and potential setbacks that come with failing. The group must make decisions that will ultimately punish an individual if the group fails, and vice versa.

Both:
- started with a game, more like a trap, set up by a homeroom teacher to his students
- explores teenage issues, troubles and worries
- Mystery genre
