So I wake up,
and there's a cute, naked loli next to me.
My husband...
Onii-san...
Arata!
Wake up already.
You're going to be late!
Honestly...
You could at least wake up on your own.
Uh...
Wha...
Okay, Lilith! Come on!
I'm not going to "come on"!
Dream World and Sub-Administer
What do you think, Onii-san?
Yep... Not bad.
You're such a perv, Onii-san.
Are you happy?
Yes. Of course.
Arin-chan, don't worry.
Hm?
I'm fine with being a mistress.
That's okay, then.
You sure that's okay?
I never thought mages would have to take PE classes, though.
Can't get enough of those bouncing boobs.
So just bouncing them is good enough?
No.
Lilith's great because she has a sexy figure,
but acts embarrassed about it.
This is pretty difficult.
Silly Onii-san.
Akio, please get rid of this impure piece of trash.
You got it, Boss.
Whoa! Hold on, hold on!
Yui-san.
Hm?
Things worked out fine last time,
but both you and that boy are still dangerous.
If something happens,
I will have to deal with you, in the name of Grimoire Security.
Please keep that in mind.
Understood?
Okay!
Th-This is...
A battle among the strongest of mages, the Trinity Seven, over Arata-san!
What?
They're fighting over me?!
Come on, everyone.
Endurance training is essential for every mage.
What are you doing over here?
Supposedly, they're going to start fighting over me.
No, they're not.
For crying out loud...
I see.
So we can settle things here, then.
Huh?
That's right.
We got interrupted last time.

I have to prove myself as his wife.
Hey, wait—
Arin-san?!
Connect to Ira Archive.
Execute Thema.
Everyone, don't use your magic here!
W-Wow.
It's Levi-san's Shamanic Spell,
Akio-san's Mantra Enchant,
and Arin-san's Chaosic Rune!
I can't believe I got to see all these great spells at once!
This is a huge scoop!
Are you sure you don't want to join in, Sensei?
Arata-san's going to get taken away from you.
H-He isn't... I-I don't...
This is all because your bouncing boobs
caused my husband to get turned on.
Huh?
What?
I can't just sit around after hearing that we're fighting over Onii-san.
Connect to Avaritia Archive!
Execute Thema!
Here it is!
Yui-san's Magus mode, which no one in the school has seen before!
And I even get to see her Archsymphony, no less!
Is it really that impressive?
Yes. Yui-san's magic is cardinal class.
If she uses it here...
Starry Night Serenade.
You're all invited to my world!
Where...
Welcome, Arata-oniisan.
Oh, it's the bigger Yui.
That's right.
I'm the dream Yui.
Do you like me better this way?
I like your big-boobed loli form, too.
You really say just what you're thinking, don't you?
Where's everyone else?
I'm having them dream something else.
See?
What on earth is going on?
Huh? Why are you not sleeping?
I used my Gehenna Scope at the last second
to reflect the spell away from me.
Mira-chan can reflect almost any spell.
Oh, yeah. You're the one who made me naked, too.
All I did was reflect that impure magic of yours.
A-Anyway, you're far too impure.
I'm never going to let this go.
Bye.
She's so cute, but scary at the same time.
You're targeting Mira-chan, too, huh?
Why wouldn't I want to be friends with a cute girl?
You really say just what you're thinking, don't you?
We should get to know each other a little better first.
Aww, that's no fun!
So you're friends with the ninja because
you don't understand friendship, right?
The ninja can't expect anything from anyone, so expectation is her Thema.
You don't care about friends,
so friendship is your Thema, right?
That's not exactly right,
but yeah.
I've been asleep by myself this whole time.
I couldn't have woken up without that jolt from you.
So I'm glad I didn't have anyone.
So my magic undid your power and woke you up, right?
That's right.
I see.
Okay, then be my friend.
Really?
Yeah.
Not just with the ninja.
I'll research that Thema of yours with you.
Yay! Yay!
I'm friends with Onii-san!
So...
Hm?
Since we're friends,
you can do whatever you want to me.
Do whatever I want...
You can't, Arata!
I'm sorry!
You can't...
Sh-She stopped me, even in her dream?
Lilith-sensei really is dedicated.
Well, I guess we should get back.
Yeah.
Oh, hold on a second.
Hm?
Thank you for saving me.
Sure!
Neither of them are waking up.
So this is the sixth member of the Trinity Seven that he's run into.
Yeah.
We don't know where the last one is.
Yeah.
Arata-san saved Yui-san, so it's possible...
He just might...
Why do you look so lost in thought, Boss?
Ow...
Sorry about that.
Today sure was peaceful.
What's wrong?
You still lost in thought?
I-It's nothing.
Come on. What's wrong?
I said it's nothing.
You don't have to be the head of Grimoire Security all the time.
You can be the real Yamana Mira sometimes, too.
Recently...
There have been more breakdown phenomena...
And some people have lost control of their magic and become demons.
With all those things happening,
maybe I'm just feeling a little defeated.
Yeah, there have been more of those.
Do you think it has something to do with
that demon lord candidate showing up?
I must purify and destroy
the strongest and most impure beings.
Don't worry so much.
Impure beings are my enemy, too.
I'll get rid of them all.
You just be the boss
and order me around to do your bidding.
Senpai...
I'll always be with you.
No matter what.
Right.
This is terrible.
Did something happen?
Yes, it seems someone came into the school last night.
Someone?
It wasn't you?
There are faint traces of a breakdown phenomenon here.
Wh-What?
I haven't done anything.
W-Well, since there are traces of a breakdown phenomenon,
the most likely suspects are you and Yui-san...
Huh?
What are you talking about?
You're right.
Those are some serious traces of magic.
Hey, Yui-san...
Your face is too close to Arata's.
Smooch.
A... A girl just...
In front of so many people...
You're so cute, Lilith-sensei.
So, Yui, were you up to no good again?
Hey, don't be mean. It wasn't me.
Besides, if my magic went out of control,
this school would have been turned into a dungeon.
Unfortunately, it appears this magic didn't come from either of you.
Actually, Lilith-sensei...
This magic feels like what we experienced in that library.
That library?
I see...
I knew it...
Library?
Yeah, Lilith and Mira seemed pretty serious when they were talking about it.
A library, huh?
I don't really get it...
You were asleep,
so it's not surprising you don't know.
Oh, yeah!
A ghost has been here!
This is pretty nice.
Oh?
You're not scared of ghosts, Arata-san?
Well, they're pretty much the same as demons and dragons, right?
N-No!
Demons are cute, but ghosts are scary!
What are you even...
A-Anyway, I can't stand ghosts!
You can't resist girls with big boobs, can you, husband?
If they don't attack, what's the problem?
There have been victims, actually.
Victims of ghosts?
Yes.
It was raining pretty heavily that day, just like it was yesterday...
The weather was bad after school,
so everyone returned to their rooms to study on their own.
But a certain pair of twin sisters
decided to stay in the library and study,
and that's when it happened.
The windows suddenly broke,
and many books came crashing down on them.
And then...
The next thing they knew, the older of the twins was gone.
No matter how much we searched,
she couldn't be found.
She's still missing.
This happened about half a year before you came here, Arata-san.
I see...
So what does that have to do with ghosts?
Even now, on rainy days like this,
people sometimes see the girl who went missing.
So basically...
If we're looking into this,
we've gotta check out the scene ourselves!
Oh, Arata.
What's up?
This ghost thing sounded interesting,
so I came to take a look.
If you came to interfere,
I'm going to get rid of you right now.
Calm down, Mira-san.
If something like a breakdown phenomenon happened here,
it's probably better if I'm around, right?
Well, Akio-san's sleeping, anyway.
Just don't get in the way.
Sure. You got it.
So are there any hints around?
Selina?
Hey, Selina.
Arata-san.
What's wrong?
Did you come to get a story?
No... I...
Hm?
You see...
What's going on?
This phenomenon...
Huh?
I'm sure we were in the library until a moment ago...
We were teleported along with the entire space around us.
We're in the Eternal Library.
That can't be...
Are you saying we were forcefully transported here by someone?
Looks like things got interesting while I was sleeping.
You guys should huddle together in a corner.
I see...
Uh, Arata-san.
What's wrong?
I'd appreciate it if you'd let go of my breast
before things get serious here.
Oh, I'm sorry.
It just fit so well in my hand...
That doesn't help!
Onii-san!
If it's boobs you like, you can do whatever you want with mine!
Wh-Whatever I want...
Be careful!
Watch out!
What are you doing, Selina?
Huh? Knee socks?
You're the demon lord candidate?
You're not Selina...
Who are...
Liese-san...
What? Why are you...
Lilith-sensei and Mira-senpai.
It's been a while.
Also, I'll be taking your magic.
You haven't said hi to us yet.
Akio and the ninja.
Looks like you've been doing well.
Yeah.
You seem to have turned into quite the evil mage, though.
Arata-san, are you okay?
Yeah... What's going on?
Well, she's...
my older twin sister.
Twin sister?
Wait... So the girl who turned into a ghost...
A ghost?
So that's what people think now?
She's the one
who went forward with the experiments to connect to the Eternal Library,
even though it was banned.
The former 2nd in Grimoire Security.
The Trinity Seven of Acedia...
Lieselotte Sherlock.
A Trinity Seven...
I didn't expect to see you all here,
along with the demon lord candidate.
This is a great chance,
so I'll be taking all of your magic.
Why did you leave us to commit such a taboo?
Well...
It was all...
for this grimoire.
To study magic.
I even entered Grimoire Security
so I could experience lots of breakdown phenomena personally.
Watch out!
You figured it out again.
I can use Logos Art, too.
I can calculate where you're going to appear.
That makes me so happy.
You really are my baby twin sister.
You've been researching,
making your magic stronger.
I think you're taking your mischief too far.
I'm going to help this time.
Me, too.
I have to stop any student going down the wrong path.
Well, I'm at a disadvantage here.
Those are some great legs.
You like legs, too, huh?
I like just about every part of a pretty girl.
That's my Onii-san for you.
You're missing the gravity of the situation!
So the rumored demon lord candidate has only just become a mage.
Yeah.
That's why when people say things are taboo or impure,
I don't get why.
Well, to begin with, magic is inhuman.
So calling any of it taboo is simply nonsense.
That makes sense.
A-Arata!
Getting your hands on a demon lord's power
would basically mean committing a taboo.
Huh?
No!
Like this.
S-Selina!
She really was doing her best to amass magic.
What a good girl.
Impure magic is increasing.
Yes, this is taboo!
There was a demon lord element sealed in the Eternal Library.
This is bad!
Now that I've acquired its magic...
I'm a demon lord candidate.
