Have I Killed the God of Calamity Today?

Everything she had was destroyed. The sunny-skied monster girl went berserk in despair, corrupted into Shigure, the Oni King who commanded torrential rain and natural disasters! After slaughtering every evil monster and god who had taken part in the siege of Peach Blossom Land, she severed every tie she had to the world of monsters. Gravely wounded, the young Oni King drifted to Yokohama in the present world, where she met the last surviving god. “An Arahabaki... The last one. I have to kill it.” Standing atop a skyscraper, she watched a crimson figure hurtling toward her. Human bodies lay scattered across the ground around her. The girl in a lead-gray hooded cloak muttered to herself as a terrifying storm of wind and rain rose around her! - [Oh no, I've been caught...] After she and Arahabaki had both been gravely wounded, the young Oni King was captured by humans. A human boy wrapped in bandages suppressed what little demonic power she had left. “Join us?” “In exchange for Shigure's life, and the chance to assassinate Arahabaki whenever I want...” “...” “Deal.” - Good news, good news! The Port Mafia has welcomed another strategic-level ability user~! The strongest area-of-effect destructive ability user! The direct aide to the Port Mafia's gravity manipulator! The monster (god) rumored to command torrential natural disasters! Ability: The Rain of Calamity “...The Port Mafia's Natsume Shigure.” “Reporting for duty.” [Come and face death with Shigure, Arahabaki.] - - “Would you cut it out already?! Who tries to assassinate their boss while he's sleeping or eating?!” The Port Mafia executive has been pestered by a strange little girl and assassinated by his subordinate again today. As usual, he's completely at his wit's end~ “...A euthanasia injection? ...For dogs?” “What idiot told you this stuff can kill a human?!” “...Wait.” “For... small dogs?!?!” “You! Damn! Dazai!” “Damn mackerel! What kind of ridiculous nonsense have you been teaching this idiot? I've already got enough to deal with!” The gravity manipulator is furious and going on another rampage! - Pairing: Chuuya (This is an if story where Chuuya joins the Port Mafia, and Hiyori goes berserk after Peach Blossom Land is invaded. It's an alternate timeline of the neighboring story, Hiyori's Peach Blossom Land~!) (It's probably a light, sweet daily-life story about happily trying to assassinate an executive every day~!) - Theme: No matter how much sorrow you have experienced, keep doing your best to live
