The timid, virginal Kouta is a new student at Kunpo High School; and while others in his situation might be a wallflower forever, Kouta has no such luck – he has attracted the attention of the busty Chizuru, who happens to be a fox deity! However, Kouta’s misfortunes don’t stop there; he’s also pursued by Nozomu, a wolf deity. Between being molested, propositioned, having his face shoved between mammoth breasts or witnessing endless panty shots, Kouta must also attempt to maintain his studies – even though all Chizuru and Nozomu want is to be the one to deflower him first!
Kanokon and Kodomo no Jikan both have light-hearted ecchi strewn thoroughout. Both are hilarious, and have a heavy focus on the corrupted girl seducing the innocent virgin guy. They each also include young or young-appearing characters undergoing acts of perversion and light-hearted seduction while the main guy tries to resist because of his ever-wavering moral fortitude.
Major differences include switches in the age differences between the main male and main female(s); Kanokon has supernatural aspects, while Kodomo is realistic; and in Kanokon, the main male actually has two females vying for his affection, one who is older than him and one who is younger.
Lotte, the princess of Ygvarland, hates men - a fact that ordinarily wouldn't be a problem given she's just a child. There's just one issue: the girl is a succubus that must suck the life seed from the male species or die! Now approaching adulthood, Lotte must learn to tolerate the opposite sex, but her royal highness won't have any of it. That is, until Judith, the girl's lady-in-waiting, brings Lotte a human boy to the demon world. This unfortunate young man, Naoya, must now open the princess's heart to his gender, but as caring and considerate as he may be, he'll certainly have his work cut out for him!
Both shows try to find humor in questionable subject matter. Normally, descriptions like "10-year old succubus" or "perverted third graders" isn't the kind of thing you'd look for in a comedy, but they both do a good job of being funny in uncomfortable situtations. Kodomo no Jikan tends to be more serious at times, but they both seem to basically be cute stories. If you like one, you'll like the other.
