Vạn Thư tossed her scrolls onto the ground filling with excitement, for the last few days she had been practicing with Yukari by throwing every best spells she had at her. Despite of that Yukari always dodge and do nothing against her. Soon she began to grow bored at the Danmaku practice and looked at the night sky with a plan that she had once abandoned long ago.

Yukari: Return to Hakoniwa? Didn't you say there was nothing left for you to return?

Vạn Thư: It was. There was one thing that I wished to learn about: the Great Hakoniwa Library

Yukari: It had been burned. There is no point of coming back.

Vạn Thư: One must not look from above but from below

Eventually Yukari allowed her to return to the Hakoniwa Library in the midnight. Vạn Thư began to blow up the entire floor which revealed a huge dungeon below.

Yukari: Why didn't you tell me to enter the dungeon with my gap instead of blowing it up?

Vạn Thư: Have a good look at this one.

Yukari: It doesn't have a name.

Vạn Thư: But it had been blocking the entrance for centuries from every magical force of this library. Without a full power that matched the god I wouldn't be able to blast through it.

The dungeon revealed many huge statues by the magical light emitted from Vạn Thư's scroll. Yukari and Vạn Thư were surprised to see a statue that was similar to Reimu's appearance in front of them.

Yukari: I assumed these statues were the founders of the Great Hakoniwa Library wasn't it?

Vạn Thư: I believe so. Long ago I heard about a myth that the founders celebrated their achievement by building the statue of them beneath the dungeon of this place.

Yukari: And this destroyed statue was me wasn't it?

Vạn Thư: I think so. This statue must have been destroyed after a failed power struggle against the other founders.

Yukari: So you told me to enter here just for this one?

Vạn Thư: No. It was because of something else.

Suddenly, a magical barrier appeared behind the entrance of the Library. Vạn Thư tossed a burned scroll onto the floor with a smile.

Vạn Thư: Don't bother reading it. I'm going to ask you a few questions. Until then none of us will get out of here!

Vạn Thư pointed her finger at Yukari with an angry face. Yukari showed her annoyed look as she asked

Yukari: I see. You lied about this dungeon.

Vạn Thư: What? You think a war advisor like me with decades of experience would permanently lose to a trickster like you?

Vạn Thư huffed as she showed the most prideful smile ever. Yukari decided to open a gap but she was surprised it didn't work as she got trapped in here.

Vạn Thư: Now. Let's begin with the most basis question: What are you trying to do with Kotou?

Yukari: Hmmm

Vạn Thư simply sat down to the stone floor next to her with a calm face

Vạn Thư: Don't even try to fight me. Your knowledge isn't comparable to a true Librarian like me. I could summon scrolls that were extinct for centuries and you would never know about it.

Yukari: It looks like my idea of testing the drug was a mistake…

Vạn Thư: Obviously you are up to no good. Ever since I saw you and your manipulative behavior I fully knew I must get rid of you so that you could stop pushing me around. That's why I purposely accepted your drug even if I knew you are trying to trick me into another trap of yours.

Vạn Thư then put her Katana onto her lap as a warning

Vạn Thư: That nameless scroll could easily disable every magical power regardless of origin unless you have a godlike power of the Hakoniwan god. The Gods of Hakoniwa built this dungeon along with an obsessive person like the other Yukari which means there should be a countermeasure against you.

This means you won't have any magic including your immortality as you have no equal power like me! Without your magic how could you manipulate me left alone escaping this place before the imperial soldiers around here got alerted by the explosion sound earlier? I bet that drug won't work for the Yokai race which means you have to test it upon me! You helped me to defeat you, ironic wasn't it?

Vạn Thư laughed as Yukari looked at her with a grim look

Yukari: Let me guess, it was the creation of the other me.

Vạn Thư: I don't care. All I care is that I got sick of you and your behavior. If both of us would die in this isolated place then so be it!

Vạn Thư pointed her blade at Yukari with a hostile look

Vạn Thư: Now. ANSWER MY QUESTION!
