All Purpose Cultural Cat Girl Nuku Nuku Dash!

A strange girl, Atsuko Higuchi, shows up at Ryunosuke's house and tells him to call her "Nuku Nuku." Her tragic past has left her with amnesia... but more importantly, he's head over heels for her! Meanwhile, Ryunosuke's mother Akiko is tasked by Mishima to retrieve their missing Androbot.

Ryunosuke's parents go on vacation, leaving him and Nuku Nuku home alone together. It's a dream come true for Ryunosuke—until their neighbor's nosy young daughter, Non, butts in. But a greater disturbance await when Mishima sends a prototype Androbot after Nuku Nuku!

Nuku Nuku and Ryunosuke go on a walk through the city together and show each other their favorite spots. But the mood sours when Nuku Nuku's a little too trusting of strange men. And then Mishima's genius inventor, Oh-izumi, dispatches his deadly flower girl Androbot to turn her into scrap...

Akiko has been appointed chief of the Runaway Androbot Capture Project! She's assigned two subordinates, Kyouko and Arisa, who immediately start causing trouble. When they go on a fighter jet joyride and start firing missiles willy-nilly, Nuku Nuku takes it upon herself to stop their rampage!

Ryunosuke's school friends spot him together with Nuku Nuku, and he tries to trick them into thinking she's his girlfriend. But instead he accidentally sets Nuku Nuku up on a date with his buddy Tsubouchi. He follows her in secret, but little do they know of Mishima's new scheme to capture her...

A very special cat escapes from the Mishima labs, and Akiko is told to find it! Meanwhile, Nuku Nuku finds kittens outside and brings them back to the Natsume house. She and Ryunosuke work hard to care for them. Then Akiko's underlings go wild again, and it's up to Nuku Nuku to stop them!
