Surviving in Blue Archive

I woke from a dream, unintelligible mutterings echoing in my ears.
I had forgotten myself, lost my past. I looked around, only to find I was already in hell,
explosions rang through the blue sky, bullets ravaged the streets like a torrent, and the fires of war burned on this land without pause.
The creatures who lived here had bodies that looked fragile yet were unfazed by ordinary firearms, they formed factions for their own ends, and spent their days slaughtering one another.
Then, they found me...
They called themselves students, and told me this place was called Kivotos.

They also addressed me as, "Sensei."
