In the present, the Japanese government has been conducting experiments to genetically engineer a human: a girl named Rizel. The experiment was a success -- sort of. While healthy and cheerful, 12-year-old Rizel also ended up possessing the uncanny need for “love” to further her development, as well as tears which were in fact volitile explosives! When sadness can end up destroying a city block, what's a girl to do except... get married?! For Iwari Tomori, the young man chosen as the most appropriate partner for Rizel, life is about to change, for better or for worse!
Both of these anime involve a little girl that is in love with a boy/man that is older than themself. I watched Kodomo no Jikan way before I had ever watched Rizelmine, but watching Rizel I kept thinking of KnJ. I also enjoyed both a lot, so if you enjoy one of these series, chances are you'll like the other just as much.
In the future, select humans have begun to evolve and acquire special ESP powers – powers that the rest of the populace fear and detest. While some ESPers are harmless, others desire to use their powers for their own personal gain. In order to suppress this threat, identify new ESPers and protect those with powers from the public, the B.A.B.E.L. organization is founded. At its helm are three ten-year-old ESPers: Kaoru, Aoi and Shiho. Together, they will put a stop to crime and attempt to gain the trust of the public; but can their guardian, Kouichi Minamoto, manage to help the girls mature enough so their selfish actions will stop hurting the world around them?
Hi there, your resident ZKC reccomender here! And you know, both ZKC and KnJ are about adults helping young girls mature, but ZKC's girls have superpowers, where as the only thing KnJ's girls have are a creepy level of cuteness
There's also a bit of comedy in both, usually at the expense of the hero.
Self-professed lover of all things small and cute, Souta Takanashi finds himself dragooned into working at the Wagnaria family restaurant by the diminutive and vivacious Poplar Taneshima. Though the pay is reasonable and the clientele polite, the high school student is often at his wits' end when dealing with the quirky staff. If the indifferent and street-tough manager, katana-carrying floor chief, and terminally weak Poplar weren't enough, Souta frequently fears for his life, as every encounter with the violently androphobic Inami ends in injury. How long can he survive before the combined stress and harm do him in?

She is the princess of Planet Deviluke, and she has run away from home to escape the prospect of an arranged marriage; and unfortunately for Rito, his accidental groping is the traditional engagement ritual of his otherworldly guest! Deviluke's emperor will destroy Earth if Rito backs down from his "proposal," but all he really wants to do is be with Saruyama! Naked antics, magical powers, misunderstandings, Lala's marriage-happy family and Rito's own shyness are many of the barriers he must face in his attempt to win the real love of his life – that is, if Lala doesn't win him over first!
Even though both are set in a different time (one being in highschool and the other in grade school) both have many similar aspects. Like, how both the male lead character have to deal with the mischievous female lead character. Also, how both female lead character initially loved the male lead character, but decided to slowly progress at the end. So if you like watching one of them you should try watching the other

Both of these anime are extremely perverted; especially the loli characters. Also, you have to make sure you watch both of these uncensored, as they are both so incredibly chopped up and editted that you just cannot take it seriously while watching it censored.
