Geki 15 and 16.
15 was the Mama Ran episode. It was cute. Ran was sweet and impatient. Can't blame her when 2 of her colleagues were turned into kids and she had to deal with it. Kid Jan was fun, I especially love the kid Geki Red. It's an odd technique for someone like Rutsu (The monster) to learn.
"Why are you here, young one?"
"To learn Rin Ju Swan-Fist!"
"Very well. But first, you must learn this technique to de-age others."

Anyway, at the end of 15, Mele awakens the Sea Kenma, Rageku, who uses her jellyfish style to become immune to most attacks as well as stinging tentacles to poison others. Seeing potential in Mele, she poisons Rio, which intensifies the stronger the Rinki in the poisoned target is (Which basically paralyzes the dude). Pitting Mele against Xia Fu, it was a neat fight. Mele using a technique to burn the cells in her body to gain strength, actually beating Xia Fu. Rio manages to save Mele (And, by extension, Xia Fu, since the killing blow would kill both him and Mele), and Rageku reveals her lesson. Jealousy. Burning anger and envy inside you to gain strength, taking both Rio and Mele as her pupils. Kata was okay with it.
