Only a little (maybe)

Thanks, literally took me a whole year and a half to think of his name.

I wanted Izaya to be different from other male harem characters by having a group of personalized bodyguards who are also his harem. Izaya made each one of them uniquely to fit every position needed to be a by the Trope harem protagonist. The idea of the Hibiki Units actually stems from a friend's dream of one day owning a personal bodyguard that's a gynoid.

Izaya is a near-moraless assassin who kills for fun and doesn't care who he kills as long as he has a good fight.
