Mermaid sisters
21 year old Vicky Largo and her 14 year old little sister Katy Largo are both daughters of a powerful, but also very sweet noble mermaid name Melody Largo.
Melody is unfortunately sick and will die soon and when she die only one of her daughters get to stay a mermaid, the other one will become human.
Vicky and Katy do not want to become human.
They both wanna be mermaids.
"We need to decide which one of you who will keep her mermaid life." says Melody to her daughters.
"I should be the mermaid of the family 'cause I'm older than Katy." says Vicky.
"Not fair! Me is much better mermaid..." whines Katy.
"Stop. Both of you." says Melody. "This way we're not going to get anywhere with this."
"C'mon, mother. You know that Katy does not deserve to be a mermaid anymore, but I do." says Vicky.
"It's true that Katy hasn't always used her powers well, but neither did you when you were little. None of you has done a clearly better job at being a mermiad than the other. I see no obvious winner." says Melody.
"Mom, please let me be the mermaid. Please!" says Katy, trying to be extra cute.
"No!" says Vicky. "I should be the one to stay mermaid for the rest of my life."
"Calm down, girls. I don't want you to become enemies over this whole thing." says Melody.
"Sorry, mom." says Vicky and Katy.
"Alright, we need to come up with a fair way to decide which one of you who'll get to stay a mermaid." says Melody.
"Easy! Just pick me." says Vicky.
"No! Me!" whines Katy.
"Girls, stop! Please calm down a bit." says Melody.
"Dear mother, you should pick me. I'm more noble than my little lame sister." says Vicky.
"I think a magic duel would be the best way to select a winner." says Melody.
"Okay." says Vicky.
"What happens to the loser?" says Katy.
"The winner gets to keep her powers and the loser will be turned human and get to go and live with your dad." says Melody.
"No!" scream Katy.
"It's so crappy that our dad is not a merman." says Vicky.
"Don't say such rude things about your father, young lady." says Melody.
"As you wish, noble mother." says Vicky.
"Better." says Melody.
4 hours later.
Vicky and Katy are each on one end of an arena, ready to battle.
"I'm ready." says Vicky.
"Me too." says Katy.
"You know the rules...begin!" says Melody.
"Aqua tyfenantus!" says Vicky and trap Katy in a large water storm.
"Brechinte neautranses!" says Katy, but her magic can not break the storm.
"You're weak." says Vicky with a sassy teasing smile.
"I'm gonna hurt you!" scream Katy in anger.
"Requintae et mungoo la puertina." says Vicky.
Katy is released from the storm.
"Gravelus de locantium et sverta!" says Katy as she boil the water around Vicky.
"Ahhh! Damn it, stupid little kid." scream Vicky in pain as her skin get burned.
"Ha! Me will win 'cause you're soon dead." says Katy in joy.
"Never! Antargum." says Vicky as she summon a white beam of magic that trap Katy in a large piece of ice.
"Control, girls. Don't kill each other." says Melody.
"Shit...!" says Katy as she break free from the ice.
"Zergaani de la jourgaevium!" says Vicky as she throw a huge bolt of thunder and lightning that almost kill Katy.
