No one POV:

Y/N Crimson. The younger sister of Guy Crimson. One of the 8 Primordial demons just like her older brother lives with the said Demon lord in the ice realm along with Velzard and some er... servants?

Guy Crimson is often said to not care about others- his younger sister was clearly an exception. In fact he is quite the over-protective type.

Guy Crimson has recently been despising the Black Primordial Noir: Diablo.

Guy POV:

Who does that damn Noir think he is? Does he think he can come to my castle whenever he pleases?

I know, I wasn't bothered by something like this before. Keyword: before.

After finding out that he is interested in my beloved sister, every second I see them together makes my blood boil.

"Ara~ You're mad again?" Velzard asked me in a teasing tone.

"You know damn well why I am mad. That Noir is getting too close to my little Y/N" I huffed.

"Y/N is younger only by 10 years, she is grown up now considering that the both of you along with the other Primordial demons are thousands of years old"

[A/N: I actually have no idea about the age of Guy but google happen to say he was about 20,000 years old!!]

"Hmph" was my only response. 

Well? How else can I react- she certainly shut my mouth with a fact.

"Whatever. She is still my little sister. If it was anyone else, my hands would have their blood. That Noir should consider himself lucky" I stated.

"Overprotective much" She replied.

This-

"Ni-san Vel-chan what are you two talking about?" My sister asked as she walked in the room. 

Y/N POV

I heard Ni-san and Vel-chan talking about something so I decided to ask them, my curiosity slowly rising.

"Ni-san Vel-chan what are you two talking about?" I asked as they both turned to me.

"Nothing important. Is there something you need?" Ni-san asked as he turn to face me, his eyes slightly beaming.

"Oh I just wanted to let you know that Diablo will be here in a few minutes"

His eyes darkened once I mentioned his name. Recently Ni-san seems to be disliking Diablo. I wonder why tho, they were good friends before.

[A/N: Dense Y/n perhaps?]

I wanted to ask why Ni-san seemed upset but before I could open my mouth, I felt myself in a warm embrace that belonged to non other than Diablo.
