Miki is a psychotic mascot, waitress and delivery girl who works at her equally as frightening mother's ramen shop. Both survivor and instigator of years of ruthless, no-holds-barred domestic violence, Miki has a capacity for destruction usually found only in people with things like "the Impaler" added to their name. Yet, she also has a kind side to her and is often found going implausible distances out of her way to rescue both proverbial and literal lost kittens, though some malignant souls might misconstrue this as merely ditching her work...
On a day like any other day, Cacao (a chocolate-loving student of magic) awoke to find himself next to a mysterious girl ... made of wood?! Named Hinano, the green-haired beauty wasted no time in professing her very one-sided love to Cacao, much to his dismay. Now, in this colorful world of magic and technology, Hinano must do everything in her power to to win Cacao's love, even when hindered by a variety of obstacles including martial arts twins, bizarre teachers, and suitors after her own heart!
While having a completely different premise, the feeling of both shows and a number of characters are very similar. The main difference between Trouble Chocolate and Muteki Kanban Musume is that Muteki Kanban Musume has more slapstick humor than Trouble Chocolate. What the latter doesn't have as slapstick, it has as original (yet weird) humor.
Keep in mind that Trouble Chocolate is a bit slower and has old art and animation which might put off fans of better animation; hence I recommend that art freaks don't watch Trouble Chocolate, while I strongly recommend the other way around.
