Isekai Cheat Magician

Nishimura Taichi and Azuma Rin were normal high school students before the light of a magic circle enveloped them after they dodged a speeding bicycle on the way to school. When the two next awake they find an unfamiliar land with forests and open fields of grass. While they're both confused by the sudden turn of events, things take another turn for the worse as a huge horse with a sharp horn on its head attacks them...

The Golden Swordsman Myura leads Taichi and Rin to the mage, Lemiya. After a reevaluation they discover that both of them possess astounding magic power, and so they begin to train under Lemiya's tutelage. During their training Rin begins to get a feel for how to cast magic. On the other hand, Taichi faces difficulty using his magic power, but just as he's about to give up on mastering his task in one day he hears a mysterious voice.

After safely qualifying to become adventurers Taichi and Rin begin working out of the inn, Mithril, completing the easiest E-Rank quests. Then one day the guild makes its decision to directly entrust them with a difficult quest, holding high hopes for their abilities. The quest is one that D-Rank adventurers have already failed twice - the investigation of a smuggling operation in the slums.

Lately there has been a string of thefts targeting Azpire's local specialty - melila fruit. As a result, prices within the city are steadily skyrocketing. Taichi and the others accept a quest to guard the melila orchards, but when the monsters attacking the fields prove to be monsters that don't live in that region, they begin to suspect that someone else is responsible for setting up the attacks. Shortly thereafter a new threat begins closing in on Rin and Taichi.

Taichi manages to defeat the Red Element with the power of the wind spirit, Aerial. So when he speaks to Lemia about hearing the spirit's voice and using her power, she pronounces him a Summoner. While he feels like that power is just another cheat, he heads into the city to find Rin and Muller. Along the way he rescues a woman being harrassed by some men, but that woman seems familiar somehow...

After defeating the golem beneath Azpire Taichi and Anastasia encounter the young magicians Milo and Melo, who command a large horde of Red Goblins. Meanwhile Rin and Muller alert the guild to an impending attack from an army of several thousand monsters. A dour mood hangs over everyone there, but Rin and Muller resolve to defend the city. Luckily that's when Lemia arrives, having sensed something wrong within the city...
