Akazukin Chacha EP35 - You're So Persistent! Nyandaber

Shironeko faints outside Seravy's house. After they carry her in, she tricks them into thinking she needs a place to stay and they offer to let her stay there. She puts a sleeping potion into the tea after contacting Dr. Mikeneko (her brother), but then drops the platter of teacups when Seravy offers her the best piece of cake, mistaking his offering her the piece with chocolate as a declaration of love.

Dorothy blows her top when she hears and subsequently destroys Seravy's house. Shironeko later tries to replace Chacha's Princess Medallion with a fake while Chacha is bathing, but is stopped by Yakko who suspects her of trying to peek on Seravy bathing. After Seravy tells her Shironeko is a guest, Yakko warns her not to try seducing Seravy, then leaves. Later, when Chacha is asleep, Shironeko tries again, but the medallion keeps moving around, keeping just out of her reach until she uses a butterfly net.

The next day Chacha and her friends see her off to meet her brother, Dr. Mikeneko. She offers them the Kitten House, a portable house shaped like a kitten head. Just when they are trying to figure out who she is, Dr. Mikeneko launches the Super Nyandaber robot. Chacha tries to transform, but then discovers the medallion is a fake. Dr. Mekeneko tries to attack them, but finds out the Super Nyandaber robot is too heavy to move just as Seravy arrives disguised as just-passing Renjishi Dancer. This distracts Shironeko so that she drops the real medallion, allowing Chacha to catch it and transform into the Magical Princess and summon the Phoenix Sword. She literally disarms the Super Nyandaber robot, and it crashes to the ground.

Afterward, Chacha asks Seravy if she can keep the Kitten House since it was left behind, and he agrees to let her keep it.
