Yes, it's normal for gang violence...and perhaps on innocent people. But when there's a lot of people missing including some gang members that looked at you, and you're getting a feeling of being stalked by some strange admirer, now that's just a whole different story...and a rather strange one.
And for your information, this stalker was Kazutora Hanemiya, former gang member, current assistant at XJ Land.
Kazutora seemed to have pretty violent tendencies and stayed hidden away, preferring not to get caught. Perhaps he'd leave some random, sometimes thoughtful gifts. One gift was a rose, and the same rose color that was your favorite color. What's even weirder is that you only stated your favorite color before you even knew about Kazutora.
On an unfortunate day, you caught Kazutora in the act of a murder. Yeah murder was normal in his eyes, but to be writing your name with the blood of the victim's? Isn't that a strange love story...and a pretty dark one. But Kazutora also wasn't so awkward about getting caught. Actually, he was so excited to see you, even stating
Darling...you can finally know who I am~! I loved you for ages, so many AGES! Are you happy to see me~? I was the one who gave you those presents~!
