I don't own Ranma. Rumiko Takashashi owns the series, as well as Fuji TV, Kitty Films.
Demon-Ranma dug his claws into Demon-Ririsu's shoulder, causing her to flinch. Demon-Ririsu responded by kicking him in the groin, then smacking him in the face. Demon-Ranma staggered for a moment, then unleashed a huge energy beam upon her, hoping to send her to hell.
"Pathetic! Is this the limit of your powers?" Demon-Ririsu laughed as she deflected it towards the Osaka Tower, turning it into scrap.
"YOU BITCH!" Ukyou tried to run towards her, but Shampoo and Kodachi held her back. "Let me go!" She thrashed in their grip, trying to break free.
"Not happening!" Shampoo shouted.
"Control yourself, stupid girl!" Kodachi snapped.
"Ririsu, you just made a big mistake." Demon-Ranma unleashed another energy beam, turning the soldiers into ash. "And now, you're next." He charged at Demon-Ririsu with a punch aimed at her head.
Demon-Ririsu just side-stepped the attack and stabbed Demon-Ranma in the chest, drawing blood. "URK!"
"RAN-CHAN!"
"RANMA-SAMA!"
"AIREN!"
"Damn... I didn't think Ririsu could be this skilled and powerful... I gotta finish this fast!" Demon-Ranma growled as he grabbed Demon-Ririsu's arm and chopped it off. Demon-Ririsu hissed in pain as she grabbed her stump. "Bastard!"
"Time to finish this once and for all!" Demon-Ranma pulled out a bottle and sucked Demon-Ririsu inside. "RAAAAAAAAAAAAANMMAAAAA!" Ririsu shrieked as she was sucked inside. Demon-Ranma then threw the bottle beyond the night sky, never to be seen again.
5 years later...
Ranma and his harem was watching their children playing with each other in the ruined city of Osaka.
"Airen, I so happy with you..." Shampoo giggled, clinging to Ranma's arm.
"What are you saying? I'm more happier than you are!" Kodachi smirked smugly, clinging to Ranma's other arm.
"You two can't even compare my joy with me and Ranchan!" Ukyou frowned at them as she sat in Ranma's lap.
Kasumi sighed. Those three were like children sometimes. She wondered how her family was doing without her presence around...
In Nerima...
Akane and Ryoga were happily married with two kids, and Nabiki was running her own business firm called, "Tendou Industries". Soun and Genma couldn't be happier, especially when the latter convinced Nodoka to adopt Ryoga as their son. But everything always had a dark side to it.
Ryoga had finally regained his sense of direction, but he also gained a drinking problem as well, and constantly abused Akane when he was drunk, and Akane couldn't defend herself due to her anger management. Also, Nabiki may had finally gotten a business of her own, but unfortunately, it wasn't enough to pay the taxes and damage repairs, and she was forced to sell her body to keep the Tendou Dojo from being seized by greedy landowners.
Soun and Genma still had their bar tabs to deal with and thanks to Ranma's rampage in Osaka, the court saw fit to see them work their debts off in community service.
Back to Osaka...
"Airen... Let's play..." The chinese Amazon tugged at his arm.
"Not without me!" Kodachi joined in.
"And me!" Ukyou added.
"Girls, Girls! You can have all the fun you need! I got all the time in the world..." Ranma laughed as he took his concubines into his chamber.
"My work here is done..." Dark Ranma's voice soon faded from his mind as Ranma began his intense sexual session with his girls...
The end.
