Lieutenant Akira
It's getting louder. The protocol. It has a VOICE now — it sounds like me, but patient. It keeps offering to take the pain away.
PILOT
And what do you tell it?
Lieutenant Akira
That pain is the only proof I'm still the one flying. Contact alarm — that's Oni-Prime's signature. Kaito found us.
Lieutenant Hikari
Then today I stop fighting the Ghost and start fighting FOR my brother. Keep the escorts off me. Whatever you hear on this channel — do not interfere.

Lieutenant Hikari
KAITO! Three months before the academy — you broke mother's telescope and blamed the gardener's cat! NOBODY else knows that! The machine doesn't know that! YOU do!
Lieutenant Akira
Its flight pattern is fracturing... it pulled the killing blow. Hikari, it PULLED the blow—
Ensign Kaito
STATIC: ...hikari...? sister, it's so dark in here—
PILOT
Signal's cut. It's retreating — no, it's FLEEING. She reached him. There's still a boy inside that ghost.

Sergeant Yuki
Hikari said not to interfere on this channel no matter what we hear. So we are not going to. Copy that, everyone. copy it twice.
Lieutenant Nakamura
Escorts on us, guns off her channel. Whatever family business happens out there today, it happens between the two of them.

Lieutenant Nakamura
Whatever just happened out there, the Oni unit broke off mid-engagement. That does not happen. Something changed.
Sergeant Yuki
I am choosing to read that as good news and I am not going to poke it. some things you just let be true.
