Az lex: be happy me

They heard the alarm. Rias gives their son to her husband.

So these 3 are sirens. Their names learn observer alpha the leader, purifier, & worst siren tester B.

Observer: i didn't think supernaturals didn't always look good looking

Rias: i can said the same about you

Akeno: ara ara so that's what you aliens look like

Purifier: I AM SO EXCITED TO FIGHT DEMONS MUAHAHAHAHAHAHAHA

Observer: lets meet the same odds shall we

Portal opened. Didn't know sirens are blue & silver colored something tells me their more powerful than the other 3.

the last one came. She looks at me with great interest.

Looking at everyone kansens got really alerted.

Empress 3: crimson ruin princess i assume

Rias: how the hell you know me?

Observer: as observer i do observe without knowing my presence

Sona: spying huh?

Observer: i wouldn't say spying

I grabbed a red sword tossed by atago. Ship girls are on stand by.

Empress: my name is empress 3. I am called the arbiter. I know who you are rias hills crimson ruin princess of the azur lane red axis
