To the Abydos Foreclosure Task Force,
Ah. Please forgive me for saying goodbye through a letter like this. This old-fashioned way just feels more comfortable for this old uncle.
There was something I didn't tell you all.
Actually, I've been receiving recruitment offers for a long time.
The condition is that I work as a mercenary for Kaiser PMC for life, and in exchange, Abydos's debt is cleared. ••••That's the gist of it.
....Uhe~ It's a better deal than you'd think, right? This uncle's skills are actually quite highly valued.
I'll handle the debt somehow. It's not everything, but this should lighten the burden significantly.
I said some arrogant things at the Black Market. I'm sorry I won't be able to keep those words.
So, the Task Force will be fine now.
I'll be leaving both Abydos and Kivotos, but it's okay.
You can resent this uncle if you want.
But all of this is a responsibility I must take.
Because I am the last member of the Abydos Student Council.
So, this is goodbye.
If we ever meet as enemies somewhere later... then, please destroy my halo.

Hoshino sits slumped over, bound by red restraints in a laboratory atop a Kaiser PMC building somewhere in the desert.
....I ruined everything.
.....I wonder what the kids are doing right now..... Will they come to save me...
After I left that letter and walked away.... There's no way they would.
Somewhere in the Abydos District...
