Erica, the S-Rank mercenary with overwhelming skill.

And Chaud, another S-Rank mercenary who follows her around like a lost puppy.

"Erica, let's be a Fixed Pair. Team up with me, only me."

"Why are you so desperate to work with me?"

"'Because I'm pissed off."

"...?"

"The thought of you partnering with some other loser keeps me up at night. It pisses me off."

Same age. Both S-Rank mercenaries. Both with personalities like rabid dogs.

Perhaps they felt a kinship deep down. That may explain how they clicked so fast.

"Erica. There's something I want so bad, I might lose my mind if I can't have this. If someone else takes this from me, it's war. Seriously."

"I have no clue what you're on about, but why glare at me while you say it? Did I steal your toy or something?"

"Every time you do that, I wanna cry."

Years later, Erica couldn't help but be flustered.

"W-what the hell's gotten into you?"

"I told you, Erica."

He spoke in a low voice.

"If someone else takes this from me, it's war."
