“In real life, people react quite normally, because Kira is very friendly and doesn’t instill fear in people. But on the internet, people are both angry and stupid, they write different things. Especially after a series of reports about us, there were a lot of reports that I was acting very stupidly since I kept a predatory animal at home.”

"My Animal is harmless, I am the real danger" or just go rip people together?
I would guess it's a kind of cosplay or japanophilia in general. I think it looks cool, so why not?
After reading that book I would not say raising a Wolf is as easy as raising a dog. It still is a wild animal that does not belong into the human world.
