Days pass and nothing is still known about the whereabouts of the classroom teacher of class 1-A.

Everyone in school is easy-going about it with the thought of that their teacher probably just went on a vacation or something, except for Ren who gets more and more curious but creeped out with every passing day.

Mizumi Kanaha -  known as ''the worst'' teacher in school, a lot of people despised him as a human being. Being too strict and negative with every lacking student, Mizumi had always looked down on low-grade students as ''scum''.

A big part of him being hated had been the way he always purposely wrote down the points on the exam sheets, of the ones he had been sure would hit a low grade, before even letting them start, as a prediction.

That was the reason Ren had chosen Mizumi as the teacher to experiment on, because he had never before seen him feel shameful about being wrong.

A week later the test bunnies - Furushima and Ken, with the expression of fear in their faces, approach Ren after school in the backyard, asking him whether he knows something about Mizumi. Ren quickly reads the situation and realizes that they feel an enourmous amount of worry because of the teacher still missing, after that bet.

Calmly, he answers that he's got no information about Mizumi and that he doesn't really care about it anyway.

Furushima exploding in anger right after that answer punches Ren and starts shouting:

''HOW COME ARE YOU IN A POSITION NOT TO CARE?! DO YOU REALIZE WHAT WE MAY HAVE DONE?''

Ren remembers about the experiment and his cooperation with them and stares with widened eyes while Furushima continues:

''EVERYTHING STATES, THAT BECAUSE OF US, OUR TEACHER HAS KILLED HIMSELF... KEN AND I HAVEN'T SLEPT, NOR EATEN ANYTHING FOR THREE DAYS IN A ROW NOW BECAUSE OF FEAR AND ANXIETY...''

Afraid that Fukushima speaks the truth, Ren composes himself and tries to calm them down:

''Listen Fukushima, nothing has been announced, calm down, Mizumi may have gone on a vacation or could've even quit the job, you know how much he hated us, right?''. 

Not being able to accept Ren's speech, Fukushima scared and furious grabs Ren's shirt and says:

You could be reading stolen content. Head to Royal Road for the genuine story.

''I DON'T CARE WHAT YOU THINK, THE OBVIOUS IS OBVIOUS, WHO WOULD ANNOUNCE TO STUDENTS THAT THEIR TEACHER IS DEAD? WHO DO YOU THINK THEY WILL BLAME IF POLICE COMES IN AND STARTS INVESTIGATING... B-but wait...''

Fukushima lets him loose and starts histerically laughing. 

''Why am i even afraid or thinking about it, i didn't give a damn about that bullshit teacher anyway, and we aren't even guilty, you're the one that made us study so that you can do your little experiment thingy... That's right... You're a murderer, the moment they announce it and start investigating, we'll just point fingers at you because we're right... Hahaha...'' 

Thinking that he may be right, Ren starts panicking and denying anything that Fukushima says. With them reaching to the point of fighting eachother, right before punching Fukushima for the third time now, Ren backs away and starts staring blankly at both of them.

''WHAT ARE YOU DOING?! WHY DID YOU STOP, I'LL JUST USE THIS AS EVEN MORE EVIDENCE OF YOU BEING AS VIOLENT AS A MURDERER.'' Fukushima shouts.

In the exact next moment, Ren, exploding in cries and screams while holding his head starts shouting as if it are his last words:

''MAKE IT STOP!! PLEASE, SOMEONE! STOP IT!! GET OUT OF MY HEAD... WHY ARE YOU IN HERE...?!''

With this gruesome scene lasting for a few minutes, Fukushima and Ken - terrified, scared and beaten up, start running away from Ren with cries when he suddenly stops and collapses on the ground - cold and unconscious.

Having stayed for a few late classes, Fukuda finished his studying and started moving out of the building, but while walking towards the stairs on the third floor, his eye catches a faint shadow through the window in the distance of the school's backyard.

Not being able to focus on whether what that is, Fukuda decides to take out his phone and zoom in at the shadow.

Seeing that the shadow is a collapsed on the ground person, he quickly calls for an ambulance and anxiously realizes with a more clear look... ''REN?!''. Leaving his bag on the gound he starts running fast towards the exit and Ren.

Finally reaching him, out of breath,he takes a moment and looks at the all beaten up and unconscious Ren thinking..

''What has this school become...''
