Synopsis
"Hey, Ralph. By the way, what's your job today, permission to kill?"

"Government official. Please kill them all for love and justice."

Oops, don't get me wrong? I and Liza are good bounty hunters who kill the crap for their clients in the tolerant crime district of Iredda, which tolerates both murder and meds. Well, it doesn't matter if the client is a good guy or a bad guy. The most important thing is money.

What was given to us was a tiny job of catching a girl. However, it was also transformed into a crazy "pleasant kidnapping drama" by the attack of the devil's different ability "Silver Master".
