Lamune is a rambunctious fourth grader who wants something exciting to happen in his life. His wish is granted when it turns out he's really a legendary hero destined to fight for the freedom of a far away dimension. The hero Lamuness is powerful, but has a weakness for cute girls. Lamuness follows in the footsteps of his predecessor, the original Lamuness, who fought over 5000 years ago.
"Lamune" is the name of a lemon soda, which tastes a lot like Fresca if you've ever had it. "Baba" is taken from the pro wrestler named "Giant Baba". Sometimes you may see his name written 'Ramune'.
Where would a hero be without a faithful sidekick? Tama-Q is Lamuness' Advisor Robot. Tama-Q helps Lamuness in his battles with his suggestions and encouragement. In addition, Tama-Q keeps the capsules of the Guardian Knight robots inside of him, which Lamuness can release by dropping coins into the slot on top of his head. Tama-Q spends most of his time sitting on top of Lamuness' left shoulder.
Tama-Q means "cue ball", like the white ball you use when playing billiards.
Milk is the youngest daughter of King Yokkohra. When not eating or screaming, which isn't very often, she accompanies and helps Lamuness on his adventures. Milk is approximately the same age as Lamune, although an exact age is never given. Milk has a short temper and an inclination toward violence (especially when hungry). Does she like Lamune or does she hate him? Maybe it's some of both...
Milk's name is fairly obvious. Yes, that white stuff you pour on your Golden Grahams.
Cocoa is the older sister of Milk. Her super-thick eyeglasses hide her really cute face; well, everyone seems to think so anyway. Cocoa is very quiet and polite, and has a knack for math, computers, and mechanical things. Basically she's the quintessential geek-girl. Cocoa can read the old scrolls that tell Lamuness where to go, and as such she's an invaluable member of the good-guy team. She also makes a very good referee when Milk and Lamuness aren't exactly being nice to each other.
Cocoa is named after Cocoa. (duh) Not the brown powder, but the liquid stuff you drink.
Cafe Au Lait is the older sister of Cocoa (and Milk, obviously)... or she would be, if she hadn't disappeared at a very young age. Cocoa and Milk never met her, and poor King Yokkora couldn't bring himself to tell them about her. What became of Cafe Au Lait?
Cafe Au Lait is a French phrase meaning "Coffee with milk"
King Yokkora is the paranoid ruler of Arara Kingdom. He helps explain to his daughters and to Lamuness some of the legend of the original Lamuness. His talent is worry, and he does that very well.
Da Cider is one of the evil sorcerer Don Harumage's best warriors. When Harumage senses the imminent danger to his evil plans, Da Cider is sent to destroy Lamuness. Da Cider's life is somewhat of a mystery, it seems he doesn't have any recollection of his childhood. Da Cider is a skilled warrior but a bit on the dumb side, and he tells really bad jokes and makes horrible puns.
Da Cider's name is probably taken from 'Mitsuya Cider', a readily available Japanese soda. In addition, 'dasai da' could be translated as "one without class".
What's good for Lamuness is good for Da Cider; his own Advisor Robot. Heavy Metal-Ko lives in the shoulder pads of Da Cider's costume, and despite the fact the pads are not connected, she can move between the two. Heavy Metal-Ko is furiously loyal to (and truly loves) Da Cider, who she refers to as "darling". She also has a burning hate for Leska. Metal-Ko carries the Queen Cideron capsule which Da Cider can release by playing his snake-charming flute.
Leska is another of Harumage's warriors. She is paired with Da Cider and given the task of destroying Lamuness. She's more cunning and generally more intelligent than Da Cider. Leska is more likely to use disguises and traps to trick Lamuness than Da Cider, who prefers the brute force approach. Like Da Cider, her past is mysterious. Leska is quite pretty, and she uses that to her advantage; and it also gives her a rather vain and selfish attitude. And oh yes, the implication is that Leska is easy.
Leska is short for Lemon Squash, which is the name of a soft drink. If you were in a cafe and ordered Lemon Squash, your waitress would be likely to ask the guy jerking sodas for a 'leska'. You may also see it written 'lesuka' or 'lesqua'.
Don Harumage is the evil sorcerer who lives in Hoy-Hoy Castle. Harumage has brainwashed many of Hara-Hara world's rulers into taking orders from him. Harumage awaits the imminent arrival of Calamity God Gobuhriki, a super powerful evil robot with which he will be able to conquer all of Hara-Hara World and Doki-Doki Space.
Don Harumage's name is a double pun. If you reverse it, you get 'harumagedon', which is Japanese for that big nasty battle at the end of the human race. Yes, that armageddon thing. In addition, reversing harumage gives you maruhage, which means "completely bald".
Gobuhriki is a take on 'gokiburi', which means cockroach. Interestingly enough, Hoy-Hoy is taken from a product called Gokiburi Hoihoi, which is a sticky roach trap.
