Fine, I'll do it myself. Two girls from the prologue of Sengoku Koihime. They are both named and voiced, they manage to assassinate an enemy general... and then they are never seen or mentioned again. They are not on the game's wiki. They're not on vndb. They're not on official website in the character list. Sure, they are unimportant officers historically, but you went this far, bring them into the story, we already have way less important officers, with sequels searching at the bottom of the barrel for more characters to add.
