Tohru decided to follow Shion Urushibara without knowing why, but was afraid to defy Michika and Misaki.

Tohru followed Shion, who did not go to the Kirishima family house - where she was currently living - but in a completely different direction.

Tohru was afraid, but decided to continue following her.

Shion, however, met with Akane Kiryuu, whom she appointed as her assistant.
Shion invited Akane inside, Tohru saw through the window as Shion murdered Akane.

Tohru watched in horror as Shion carried the bag out and, what surprised him most, got into the car and drove away.

After Shion drove away, Tohru called Misaki and Michika with a trembling hand.

After Shion drove away Tohru called Misaki with a trembling hand.

Tohru: M-michika...?

Misaki: What?

Tohru: Urushibara-san... Urushibara-san...

She...

Misaki: She what?

Tohru: She killed Kiryuu-san.

Misaki: Something else?

Tohru: She's driving the car?

Misaki: Are you all right?

Tohru: I'm not joking, she's serious...

Misaki: Let it be that I believe you.

Do you know what her "parents" do for a living?

Tohru: I don't know...

Misaki: No matter, but from what you say her parents are away.
Perhaps this is part of their routine.

After that, Tohru met with Naomi, he was traumatized but tried to hide it from her.
Naomi, however, sensed his unusual behavior and knew something was fishy.

Naomi: Eh? Everything okay Tohru?

Tohru: Y-yeah… I just had a bad day..

Naomi: Bad day?

Tohru: I saw something I'd rather not have seen...
Naomi….
We need to stop this….

Naomi saddened
Naomi: I know… but how?

Tohru: And just now, I would like to give you an answer to your question.

Tohru blushed, and looked deeply into Naomi's eyes.

Naomi blushed as well.

Tohru eventually kissed Naomi for the first time, Tohru overcame his shyness, and decided to take this bold step...

Naomi: Tohru…

Tohru: I love you Naomi…
And I wouldn't say the same thing about Shion…

Tohru: Did she did something?

Tohru nodded.

Naomi: Are you saying that... Shion murdered someone?

Tohru: Well, yes…

Naomi: You should call the police.

And even now you should do it...

Tohru: I'm scared, but I think it would be appropriate to do it...

I will do it myself, Naomi.

Tohru called the police.
Police soon showed up at Kirishima's home.

They found only Shion, whom they arrested.

She was charged with the murder of Akane Kiryuu and driving without documents, however, Shion excused herself, and after a few days was released, finding Akane Kiryuu's body, along with the knife with which she was killed.
Fingerprints were compared, and it turned out that they did not belong to her.

The police officers were confused, however, only after a week she was released.

After Shion returned to class, her position was weakened.

During her absence, Countermeasures was reorganized.

The new composition included.

Yuuichi Kasuga - Head of Countermeasures

Miyuki Asahina - Deputy

Arisa Serizawa - Auxiliary officer

Shion reacted nervously to this information.

Shion: Kasuga-kun, aren't you too comfortable in my place?

Yuuichi: Urushibara-san, you have been away for the past week, in addition, you were suspected of Kiryuu-san's murder.

You unfortunately lost the trust of the rest of the class.

Arisa: Do you really think that a person suspected of murder can still hold such a position?

I trusted you, Shion.

Masato Yurugi came closer to Shion aggresively.

Masato: Isn't it suspicious that every family Urushibara went to died?

I wonder why Shion wasn't in her former home when the Akazawa family died.

Shion: I was with Kojima-san at the time.

That's a misguided argument, Yurugi-kun.
I just have bad luck.

Yuuichi: I'm not saying you're guilty of the death of your foster family, but it's quite suspicious, on top of that with accusing you of Kiryuu-san's death.

Miyuki: Such suspicions should rule you out Urushibara-san.

Arisa: However, you will still be able to participate in voting.

By the way, today we want to abolish isolation.

We have been waiting for you, we want every vote to count.

Shion: Such decisions should not be made by the Countermeasures themselves with the Commission?

Yuuichi: I spoke with the Commission, both Honma-sensei and Ueda-sensei agreed to make such a decision, besides, it was Asahina-san's idea.

And I am of the same opinion as her, we should ask the class what they think.

Miyuki: I think we can start voting, just write "yes" or "no" on the pieces of paper.
