Nice to meet you, Masters! I am the leader of ButlAristocracy, also known as Batrari, Hiyo Inugami! ...Actually, let's drop the formalities! Yeah, if I don't stay relaxed, I'll just get exhausted! So, let's try that again! I'm the one serving as Batrari's center, "Hiyo Inugami"! Nice to meet you, Master ♡
The ray of hope for all you Masters, Kai-sama— that's right, the Great Me has arrived! I'll make sure you can't look at anyone but me, so you'd better be prepared, okay? ...Ah, I need to introduce myself? I'm "Kai Mido." I don't think there's any need to say it at this point... but well, you'll need to know my full name to fall in love with me.
The rising star of your expectations—and I'm a boy, not a girl! Chiru-chama, also known as "Chiru Himezono," has arrived! Don't look at that narcissist or the guy with the middle part, make sure you're looking only at me, okay?
