=Klein's POV=
Another day, another problem. Arin was staring at me at class, and following me wherever I go.
Klein: Lilith, although I don't understand emotions, I feel weird being followed and being stared by a girl I don't know. So let me ask you what the hell is she doing?
Lilith: No... I wonder...
She looked distressed.
I ate at the canteen while staring at her as well, I was walking towards the next class while she was following.
Klein: 'Nature's calling me.'
I went to the comfort room to pee when I saw Arin follow me.
I grabbed her by the shoulder and pushed her outside. I pointed at the sign outside the comfort room.
Klein: Read it.
Arin: Boys' Toilet...
Klein: What are you?
Arin: A female human.
Klein: So that means you must not enter-
Arin: But I don't mind...
Klein: Haaaah, you got to be kidding me.
Grimoire: Well, never saw you worked up because of a girl.
It said as I raised it.
Klein: Yeah yeah.
Arin looked at grimoire.
Arin: Is that a grimoire?
Grimoire: Hello, nice to meet you. I am Astil Manuscript, I still have no name.
Klein: Want me to name you?
Arin: Arin Kannazuki.
She looked at the grimoire with a little smile.

Arin: Let me borrow it for a sec.
Klein: Sure.
Grimoire: My master is looking at you.
Arin: In a perverted way?
Before the grimoire tells yes, I already answered. Avdol style...
Klein: Yes! I am!
Why? I would rather humiliate myself than being humiliated by others.
I ran to the toilet and peed. After that, I rushed back to Arin. It feels good to let out the yellow liquid.
Klein: So, what do you want? Why are you following me?
Arin: Hmm? Getting over over self-conscious?
Klein: Nai, you are too obvious.
Arin: How troublesome. I am watching the Demon Lord Candidate...
Klein: Hmmm...
Arin: And it seems I will be the Demon Lord Candidate's partner.
Klein: Partner?
Arin: Wife, new wife, young bride, young mistress. Choose one.
Klein: I am sorry, I would rather be alone with Alex since he can't die. Everyone who gets closer to me gets killed and I don't want you to be one of them. But why are you asking this?
Arin: The Headmaster said so...
Klein: Headmaster?
Master Biblia: Call, and I shall come flying forth!
He crashed at the window.
Klein: Hmmm.... Let's go talk to Lilith instead.
Arin: Right.
Master Biblia: I was ignored....
=Infirmary with Alex, Lilith, and Arin=
Klein: I see, now I get it.
I looked at Arin and asked again.
Klein: So, anything or two that you need to tell us?
Arin: Are you talking about the time I locked all of you in one room?
Alex: It was you!?
Lilith: Arin!
Klein: Arin.... Marry me.
The two looked at me weirdly.
Klein: Sorry, I meant to say 'Thank you'. So why did you do it?
Arin: Because the headmaster said that you might cause a breakdown phenomenon once faced in dilemma. I was bored waiting so I just trapped all of you inside.
Lilith: But why Breakdown Phenomenon?
Arin: This is the reason.
She came closer and held my hand.
Arin: Connecting to Ira (Wrath) Archive.... Executing Thema.
She changed into her magus mode. It was at this moment that I knew, I fucked up.
