If you liked the History's Strongest Disciple Kenichi manga, the Anime-Planet community thinks you'd like:
While rummaging through his grandfather's possessions, Hikaru Shindo stumbles upon an old bloodstained Go board. Much to his surprise, he also finds that the board is inhabited by the spirit of Fujowara no Sai, a Go instructor to the Emperor during the Heian period... and he's going to reside in Hikaru's body! Urged on by Sai, Hikaru begins to play - albeit with no intention of playing seriously; though as Sai teaches his host about Go, he awakens both Hikaru's interest in the game as well as an innate hidden talent for it. Before long he finds himself paving his own path in the world of Go. Although Hikaru is naturally skilled, does he have what it takes to defeat his rival, Akira, without Sai's help? And will he ever be able to achieve the ultimate move known as the ‘Hand of God'?
A board game vs. martial arts doesn't seem very similar at all. However, if you think of each game Hikaru plays as a fight, they relate quite well. Two protagonists slowly growing stronger by taking on new challenges. Kenichi and Hikaru also both have incredible masters. I know nothing about Go, even after watching Hikaru no Go, but I still enjoyed it a lot.
Five hundred years ago there lived a feudal lord with a vast amount of spiritual power. To keep it from falling into the hands of demonic Ayakashi, the mage Tokimori Hazama and his two students were called to defend the land. However, they fell ill, and the feudal lord was killed and buried on the land now called Karasumori. Years later the successors of the Hazama students, Yoshimori and Tokine, have inherited the powers of the Hazama clan. They are Kekkaishi, users of the Kekkai, a secret and powerful technique that creates a strong barrier to capture and eliminate Ayakashi. Protectors of the power buried beneath Karasumori, Yoshimori and Tokine spend their days in the school built on the land, and their nights defending it from attackers who wish to use the power for their own purposes. With Karasumori's power growing more unpredictable everyday, will Yoshimori become strong enough to protect the ones he loves?
At first these two might seem different because of the setting and premise, but they share many underlying themes. we have a younger boy infatuted with a older and more skillfull female. the female leads of both stories slowly come to respect the protaginists as they grow.
Another similarity between the two exist in how tactics and skills are employed in battles as they are learned, instead of random powerups
Both kongoh bancho and HSDK contain over the top fighting, and some near superhuman characters. HSDK has more character progression and is more enjoyable(in my opinion) and in-depth, though both are fun and crazy shounen/fighting manga.
There's an adage that one man's trash is another man's treasure; but for Kosuke Ueki, one man's trash is another man's... tree?! Junior high school teacher Mr. K is in the running for the title of Celestial King. Candidates must select a junior high school student to endow powers upon, and then the students might fight each other mercilessly. The victorious student's benefactor will become the new Celestial King! Kosuke was Mr. K's choice, and for his power, he chose the ability to turn trash into trees. Furthermore, if he uses his abilities to harm others, he will lose one of his natural talents. Now, Kosuke must battle a variety of other power users to help Mr. K win it all, all while keeping his talents intact!
Aside from a general, "Shounen FTW" aspect, both Law of Ueki and History's Strongest Disciple Kenichi share a few similarities that make either one worth trying if you liked the other. Both focus heavily on the idea of justice, and right and wrong, as well as that of hard work. While the two protagonistsare complete contrasts in terms of natural ability, both place heavy emphasis of working hard to achieve their goal. Both also have a similar tournament-esque format with the characters progressing through ever-increasingly difficult fights.
Middle school student Tsuna has always gone through life in last place; but when he learns that he is getting a tutor to help him raise his game, he had no idea that his benefactor would turn out to be... an infant and a mafia hitman?! As if things can't get much stranger, Tsuna then discovers that the powerful Vongola family has chosen him to be its next successor - a position that has control over all mafia families. Joined by friends Tsuna unwillingly starts out on his path to becoming a mafia boss - if he can survive the training!
Kenichi and Reborn! both star incredibly timid and weak high school boys. Both Tsuna and Kenichi also are motivated by their feelings for their friends and especially the girl they like. The battles get more extreme as each series progresses and the comedic nature stays strong throughout the series.
