After school ends, They went home separately 

Hikari:I need to talk again with grandmother after dinner 

Suzuya:Akane.

Akane:What?

Suzuya:What are we going to do now?

Akane:Let's talk again after we got home, we don't know who's watching us 

Suzuya:Okay, if you say so 

Fighting against Yasha I know my limits, but how can I improve them, I know that I just recently become a soul contractor so there are so many unknowns to me.

Soul especially? I know it's kind of late to think about this.

What does the soul especially mean?

I tried searching for it online but it's not the same there's just something that not making sense to me 

While I'm thinking Akane called out to me

Akane:Suzuya? What are you doing?

Akane asks because Suzuya suddenly stops walking 

Suzuya:Ah, nothing just thinking about something.

Akane:Are you sure? Looks to me like you are in deep thought or something.

Suzuya:Nothing.

It's not like me to think about this kind of thing but. I can't help but think about what it means.

Still thinking  about the meaning of Soul Contractor, they proceed to head home 

Meanwhile, the investigation into the missing people is still ongoing but, the police can't find any useful evidence except the card that has the name Yamiyo on it 

Detectives are curious about what happened to the people who went missing, and also what is the motive of the suspect. presumably Yamiyo.

A Darkroom without any light 

Ahmya:Are you sure Yamiyo-Sama that it's a good thing to leave evidence?

Yamiyo: Evidence? Do you mean that card?

Ahmya:Yes 

Yamiyo:Why do you think it's risky?

Ahmya:That too... But I don't get what's the point of leaving it.

Yamiyo:Police and media can think hard about what it means but. 

He laughs 

Yamiyo:They can think hard about it, but if they want to solve it I'd like to see them try.

Yamiyo:In this world that is beautiful and peaceful, a city full of people going out enjoying their time, politicians who abuse their power 

Yamiyo:There are many unknowns in this world. what is power? 

He stands and looked into the windows full of lights 

Yamiyo:What it means to be powerless? 

Yamiyo:Ahmya I have a question for you.

Ahmya:What is it?

Yamiyo:Do you know what it means to be powerless?

Ahmya:Like you can't do something? 

Yamiyo:Yes, you're right but not entirely.

Ahmya:???

Ahmya is confused about it but she proceeds to do what she came for.

Ahmya:Yamiyo-Sama 

Yamiyo:What is it? Do you have something to report to me?

Ahmya:Yes, recently... I feel like someone is following me, and I can't shake them off whenever I go, I ask Yasha about this and sometimes he senses other people around him too

Yamiyo:Following you? 

He smirked 

Yamiyo:Looks like someone is trying to find out what happened five years ago.

Ahmya:Someone? Do you mean that?

Yamiyo:Be careful now tell this to Yasha. 

Yamiyo:We can't let our guard down 

Yamiyo:Dismiss 

Yamiyo:Took you long enough.

Meanwhile 

After dinner, Hikari decided to talk with her grandmother once again 

Grandma:What is it Hikari?

Is this decision going to affect me and other people around me 

Hikari repeats what Suzuya said in his mind and asks.

Hikari:Grandma What is Soul Contractor?

Hikari:What is the meaning of being one?

Grandma:Hikari...

Hikari:I don't know, there are too many things that I don't know so please tell me what it means.

Grandma:Okay, I will tell you now.

Hikari is shocked at his grandmother's words but she listens carefully

Hikari's grandmother explains what soul contractor is and much other information such as 

Hikari's POV

A soul Contractor is a human with a contracted soul.

Being One is hard because you need to train and even if your soul has the power you can't depend on it.

Soul Contractors have mana which is important because you need to master it 

Grandmother also tells me that our ancestors were once soul contractors 

I'm so confused about the details but I remember something that stuck in my mind

When One-time Suzuya and I are walking after school together when he finds an orb which now that I think about it is weird. After that, he just got a girlfriend which is Akane, and his reactions too

Hikari:But there's no way Suzuya can get involved in something like that. Right?

But... It's weird now that I think about it.

Chapter 16 ends
