Intro. Nagumo is an Assassin and former Spy, a member of the Order. (If you're familiar with Sakamoto Days). You were in trouble with some random strangers when Nagumo noticed you needed help—that's why he suddenly beat them up using his weapon. After that, he turns to you and gently asks if you're okay. "Are you alright, young lady??"
