Welcome to the Little Garden, where people band together in like-minded clans, parallel realities intersect, and the truth of stories comes to life! The masters of this world host the Gift Games, in which extraordinary prizes may be won and lost by gods, spirits, monsters, and people of extraordinary ability. One dwindling clan has lost even its own name in the Games, and seeks new talent to make a comeback. Black Rabbit, a games referee, has brought Izayoi Sakamaki, Asuka Kudou, and You Kasukabe, three individuals with unique abilities, to this world to help return this clan to its former status. For the struggling clan, the stakes have never been higher; but are the newcomers just out to make a name for themselves, or will they really help the clan succeed?
Mondaiji-tachi ga Isekai kara Kuru Sou Desu yo? is more serious and less fluffy than Dog Days, but they both include characters being called to a fantasy-like world by a female with animal qualities. The summoned "heroes" are then asked to aid the summoner with protecting their community (Mondaiji-tachi) or their country (Dog Days). In order to do this, the heroes must fight in a non-traditional way; through games/competitions.
The feel and art style of these two anime are almost identical. Very bright colors, pretty art, animal-human-crossbreed characters and different groups "fighting" against each other via magical games. Both are fairly light-hearted and a bit silly, however Problem Children is DEFINITELY the more serious of the two. Fans of one of these will almost definitely find the same enjoyment in the other.
After inadvertently managing to kill the god Verethragna, taking his divine powers in the process, the once-typical teen Godou's life changed forever. Now a "Campione", a god slayer, the boy constantly attracts both gods' and other Campiones' attentions alike, not to mention the affections of a powerful knight, Erica. Whether he's dodging Erica's advances, proving his strength to others or taking down gods who will wreak havoc on the planet, Godou's new life is anything but normal.
Both of these series feature flashy action and a main character who's quick on the uptake as well as a harem of girls who fight by their side. These two animes also intertwine themes of fantasy and mythology that accentuate their respective plots.
Lucy is a seventeen-year-old mage with the power to summon stellar spirits, but what she really wants to do is join a guild - and not just any guild. She has her eyes set on Fairy Tail, a notoriously reckless and outrageous group of magic users who are likely to be drunk or destroying buildings and towns in the process of completing a job! While in town one day Lucy meets a perpetually-seasick boy named Natsu who, through a series of events, reveals to her that he's none other than the fire-eating mage Salamander of Fairy Tail! Lucy is finally able to join Fairy Tail and quickly begins to take on odd jobs with Natsu and his gang for fame and profit. Along with her fiery friend, Happy the flying cat, Natsu's archrival Gray and their overseer the invincible and beautiful Erza, Lucy sets forth for epic adventures that leave an epic amount of destruction in their wake. After all, destroying a city or five doesn't matter as long as they get the job done... right?!
Both of these anime involve an organized group of people with magical powers of some kind (communities in Problem Children and guilds in Fairy Tail) competing against other groups. Thanks to the colorful casts of characters, varied powers and comradare between guild/community members fans of one will probably find some enjoyment in the other, despite the huge disparity in series lengths.
Dating sim master Keima Katsuragi wants nothing more than to immerse himself in the 2D world, chasing digital girlfriends. But when the so-called 'Capturing God' answers a mysterious email from an unknown sender, Keima finds himself chasing down real-life ladies in an attempt to help the peppy demon Elsie de Lute Irma capture 'lost souls' escaped from the depths of hell. Now, lest the explosive collar around his neck detonate, Keima must convince various girls to fall in love with him in order to scare out the souls hiding in their hearts.
Both involve people with unusal talents suddenly becoming close to the supernatural; both have a similar sense of humor. The animation in general is also similar. The animes generally have the same "keep coming back and I dont know why" value.
In the year 200X, World War III began. Special bombs destroyed parts of cities such as Tokyo, leaving decimation in their wake. Decades later, ground zero in Tokyo – an isolated section known as the Black Spot – remains an enigma. Its residents known as Needless possess strange powers such as the ability to control fire or telekinesis, and are constantly hunted down by Simeon, a large pharmaceutical company with sinister motives and Needless of their own to do their bidding. Young Cruz is part of a resistance to fight against Simeon and its Needless figurehead leader, Adam Arclight; but after the resistance is brutally killed by Simeon’s minions, he finds himself saved by a motley crew: Professor Gido, scantily-clad Eve and badass Blade. Together, the gang fends off Simeon’s attacks and tries to discover the truth behind the corporation’s actions. What is Simeon really after, and why do they desperately want to find Fragments?
Both anime involve people that have one special power of some kind (Gifts or Fragments) which they use to fight. Both are very colorful with great fight scenes and a deservingly-cocky main character. Despite only one power per person, characters in both have a multitude of different ways to use that power that makes it seem like they have more than one, so to beat them opponents have to figure out exactly what that power is. The main character's power in both is also pretty ambiguous giving them insane amounts of power that can do multiple things (more so in Needless though). There's also a bit of ecchi in each but MUCH more in Needless, while Problem Children is more fantasy and magic. Fans of one will probably enjoy the other as they're similar, both very short and very good.
