Sanpeita Kobayashi made a Childhood Marriage Promise ten years ago. To this day, he still keeps her photo around in his wallet. His life is about to change. One day, a Super-Deformed Powered Armor calling itself Kemeko blasts into his life and declares Sanpeita to be her husband. He now has to live with Kemeko, who was apparently sent to protect Sanpeita from the Mishima Electric Corporation, a Mega-Corp that is after his power. It doesn't help matters that everyone around Sanpeita is some degree of crazy.
Kemeko Deluxe! is a shonen manga by Masakazu Iwasaki, which was serialized from 2005 to 2011 (starting in Dengeki Comic Gao!, and moving to Dengeki Daioh in 2008 when Gao ceased publication) and compiled in 9 volumes. It was adapted into an anime by Hal Film Maker in 2008. The anime covers the first two and a half volumes of the manga.
For those that prefer legal options, the anime version can be watched on Crunchyroll.
Tropes in this series include:
- Action Girl: Ryoko Kurosaki, who manages pretty well in combat against Kemeko. As it turns out, she's also a student in Sanpeita's class, she just rarely shows up; she also has a cute cat sidekick.
- Applied Phlebotinum: The Nanoball is said to generate infinite energy out of nothing.
- Airplane of Love: Sanpeita has one of these in the first episode while Sitting on the Roof, thinking of his impossible 10-years-past Childhood Marriage Promise.
- Butt-Monkey: If you're not convinced Sanpeita is one, then what anime have you been watching...
- Cooldown Hug: Used by MM on Sanpeita after the Nanoball makes him experience his first Superpower Meltdown.
- Cosplay Otaku Girl: Sadly, Miura isn't a real maid... but that doesn't really diminish her awesomeness.
- Elaborate Underground Base: Kemeko has rebuilt Sanpeita's school as her fortress, full of concealed weapons that pop up on EVA-style lifts.
- Cute Kitten: Ryoko's cat Juumonji, who can take down grown men and androids, keep an eye on Sanpeita and give a darn good massage.
- Fanservice: Please, for the love of god - more M.M. fanservice! And more Kurosaki fanservice, too! And Izumi and Miura and Sanpeita's mother...no, wait...
- Frank's 2000 Inch TV: Mishima's 2000 foot headquarters screen. It's the biggest thing in the city, and dwarfs every building around it, spanning what looks like at least ten city blocks across.◊
- Frying Pan of Doom: Tamako, Sanpeita's little sister, effectively turns a frying pan into a weapon when she goes to fight Kemeko, believing her to be a burglar. Later in the manga, she uses two of them chained together nunchuku style for her Electrical Parade Attack.
- Gatling Good: Kemeko has used one of these on several occasions. Including in class. Although the anime uses a five barrel model, the manga has always had six, which is important in volume 5.
- Hammerspace: MM manages to fit into the Kemeko unit despite being bigger than it. Also where she keeps her BFGs.
- Imagine Spot: When she's packing for a trip to the beach, Izumi lapses into a romantic vision of her and Sanpeita watching the sunset. Sanpeita is unusually buff in her imagination.
- Last Episode, New Character: Kamishiro Yukina, miko and nanoball prototype, who appears in the manga a couple of chapters after the last anime episode. She appears right before the end credits.
- Megaton Punch: One of these, combined with a massive nosebleed, puts Sanpeita into critical condition in episode four.
- New Transfer Student: Subverted when a new transfer student is predicted - then Kemeko bursts through the window. Kemeko is not the new transfer student, though. That role belongs to a named extra completely unrelated to the main plot.
- The Ojou: Haya-chan is rich. In episode 9 she reveals that she is the "third-generation boss" — i.e she could be in line to head a Yakuza family.
- Paper-Thin Disguise: Used unsucessfully by Miura, using a cat mask and claiming to be "Neko Mimi Maid Kamen". Later, she dresses as Kemeko (with a Sanpeita dummy made of cardboard boxes that almost fools Izumi).
- Parental Obliviousness: Fumiko Kobayashi, Sanpeita and Tamako's mother, is a mangaka and frequently pulls all-nighters. She's oblivious in general, but the all-nighters don't help.
- Poor Communication Kills: As of Volume 7, MM still hasn't bothered to tell Sanpeita what's going on, leaving him to get the information from her less-than-truthful mortal enemies.
- The Reveal: In episode eleven, M.M. is revealed to be Mishima Mei, daughter of Mishima Souichirou, the founder and first president of Mishima Electronics, whom she killed to steal his ultimate invention, the Nanoball (according to Vanilla). This also makes Kemeko a Phlebotinum Rebel. Using the power of Mishima to fight Mishima.
- Among many other things, the show contains shout-outs to Magical Witch Punie-chan and Bludgeoning Angel Dokurochan (episode seven), written and directed by the same man who directs Kemeko itself. Also Neon Genesis Evangelion, through Kemeko's plug suit and a very conspicuous Lance of Longinus weapon
- There's a couple of Sayonara, Zetsubou-Sensei shots in episode 2 of the anime when Tamako attacks Sanpeita.
- Aoi does a Urusei Yatsura shoutout in chapter 8.
- Shower Scene: M.M. takes one after Sanpeita tries to find out her true identity in episode eleven, so it may also qualify for a mild Shower of Angst. Izumi, too. Both with lots of Censor Steam.
- Standard Snippet: Beethoven's "Ode to Joy" is played when Sanpeita is lucky enough to see Izumi's bikini top fall off right in front of him. The version played even has a chorus backing it, making the moment verge on Mundane Made Awesome territory.
- Sweet Tooth: Ryoko gets orgasmic over sweets.
- Transformation Trinket: MM has a little watch that she can use to summon Kemeko from a distance. It's rather nifty.
- Wise Beyond Their Years: Misaki is way more perceptive than she makes herself appear.
