On her way to the Great Wall, Mikaboshi has a heart-to-heart talk with Irotis. After saying goodbye, she goes on to draw the Great Wall over and collapse it directly above her and the Grandsleuth, the resulting boulders damaging the Legion Void below.
Meanwhile, Mikaboshi calls out to empty space from the Grandsleuth's deck.
Mikaboshi
Shitori.
Irotis
...
Mikaboshi
Did you see the Great Wall? Who'd have thought we'd ever lay eyes on it again.
Irotis
Lyria and Vyrn were saved, but the Otherworld...
Mikaboshi
To be honest, I knew this would happen.
Irotis
Wha...
Mikaboshi
That you would betray me.
Irotis
...!
Mikaboshi
I am an Astral after all.
Mikaboshi
Being one of the stronger Astrals, I was given charge of my own skydom.
Irotis
Th-then why...
Mikaboshi
Because I also knew the reason you betrayed me.
Mikaboshi
You did what you did for my sake, not for anyone else.
Mikaboshi
You even went so far as to sacrifice yourself...
Irotis
...
Mikaboshi
It was the first time anyone had gone to such lengths for me.
Mikaboshi
I felt blessed, even if your actions were a betrayal.
Mikaboshi
And I did confront you at one point to hear your thoughts on that...
Irotis
I... I'm sorry...
A semblance of her old self can be heard in her apology, which pleases Mikaboshi.
Mikaboshi
You're an amazing person, Shitori...
Mikaboshi
It wasn't some skydweller plot that stopped a monster from destroying her own kind...
Mikaboshi
No... It was all you. To know that you cared for me meant so much.
Mikaboshi
It was your love that saved Nalhegrande, and me as well.
Mikaboshi
That's why I know you can do this, Shitori. You can even save the world if you set your mind to it.
Mikaboshi unceremoniously approaches Irotis and wraps both arms around her.
Irotis
Mother?
Mikaboshi
Shitori... Open a door to the Edgelands.
Irotis
Um, okay...
The moment Irotis creates a portal to the Edgelands, Mikaboshi knocks her into it.
Irotis
...!
Mother!
Mikaboshi
Stay there!
Mikaboshi
Go to where everyone else is.
Irotis
Huh? Mother, what are you—
Mikaboshi
Goodbye, Shitori.
Mikaboshi
No matter what happens, you'll always be my beloved daughter.
Irotis
W-wait! No!
Irotis
Mother!
Mikaboshi
...
Upon making contact with the primal beast Ebisu, Mikaboshi uses her Astral powers to close off the door to the Edgelands.
After making sure that Irotis is safely on the other side, Mikaboshi heads straight for the skies above the Legion Void.
Mikaboshi
(Loki, Gran, and Gran's dad... I'm sorry, everyone.)
Mikaboshi
(The Grandsleuth probably isn't going to survive this either.)
The massive Great Wall in the distance begins moving gradually toward Mikaboshi.
Mikaboshi
(No matter where I go, the wall ends up being nothing more than a coffin for me.)
Amused by the irony of it all...
Mikaboshi directs the wall to move toward the skies directly above her and the Legion Void.
Mikaboshi
(As the one who created this weapon, I claim full responsibility.)
She commands the Great Wall to collapse on the spot.
Giant boulders, each the size of a shack, fall around Mikaboshi.
Mikaboshi
(When I accepted my fate to be sealed together with Shitori following her betrayal, the monster in me died and I became a mother.)
Mikaboshi
(Yet here I am again, falling with the Great Wall.)
Mikaboshi
(I may be alone this time, but I feel neither afraid nor lonely.)
The massive cascade of Great Wall pieces descend upon the Legion Void, cutting and chipping away at it all over.
Finding herself devoid of sight and sound, Mikaboshi mutters under her breath.
Mikaboshi
Leaving something behind as a parent might not be such a bad thing after all.
With those final words, Mikaboshi disappears into the smoke and dust of the collapse.
