So, you’re wondering where Asseylum went?
Though she was shot (multiple times, at that) by Saazbaum, she didn’t die. Slaine took her.
As it turns out, after being kidnapped(?) by Slaine and going under hiding for years until the war had ended, she lived a normal life, marrying someone (dunno if it’s Slaine or some other guy).
Years have passed, and what you see on the last pic is her daughter, making her way towards being a member of Takayama’s harem.
Hahaha, silly me.
