Koyuki Koyuki – författare

Soujirou is conducting special training in hopes of acquiring power from outside the system. However, right about then, an army of more than ten thousand Goblins appears on the Zantleaf Peninsula! In the face of this unprecedented situation, the West Wind Brigade musters its best fighters and sets off to guard the Ancient Court of Eternal Ice, where the nobles are assembled!

A mysterious Person of the Earth maneuvers covertly in the shadows of the capture of the difficult quest, The Return of the Goblin King. Does he hold the secret to the Adventurers' resurrection?! Soujirou clashes with an eerie, formidable enemy with powers that surpass the common sense of the game! As sparks fly, how will the battle play out?!

Does the “Cautious Hero” have a plan for taking on General Deathmagla’s army?! The misadventures continue of Seiya, the absurdly overcautious hero who tried to buy a thousand bottles of holy water as soon as he knew he’d be fighting undead, and Rista, a goddess who’s always waving her literally “holier-than-thou” attitude in his face! Things start off badly when Seiya immediately butts heads with the dragonkin who were supposed to become his allies—and does he have a plan for dealing with the army of ten thousand undead approaching the town?!

Is it time for Seiya’s bag carriers to fulfill their destinies?! Seiya probably doesn’t need to get any stronger, seeing as he just took apart a seemingly invincible monster with his bare hands, but you can never be too careful! This time, he’s headed to Dragon Village-along with Rista and his bag carriers, Mash and Elulu-to acquire the holy sword Igzasion. The ultimate weapon is surely a must-have for anyone as pathologically overprepared as Seiya, but what will he have to sacrifice in exchange...?

The Equipment Hunter returns with his sights set on one thing - Kuroe. But no way is Soujirou going to let him take her! With the Equipment Hunter's natural enemy in tow, Soujirou and the West Wind Brigade are gonna give it all they've got in this second fight to the death!

Can a neurotically overprepared hero and an underachieving goddess save a parallel world together?! When the inexperienced goddess Ristarte is tasked with the daunting mission of saving the S-ranked world Gaeabrande, she thinks that summoning Seiya Ryuuguuin, a Japanese teenager who has utterly broken stats as a Hero, will finally turn her luck around. Seiya’s abilities (and good looks) are all she has ever dreamed of, but she soon wishes she had read the fine print about his ”overly cautious” personality...

Will Seiya’s… “unique” methods stretch a new ally to the breaking point?! No sooner have Seiya and his friends made it back from Dragon Village than it’s time for them to face a new enemy— the Demon Lord’s army’s Aerial Assault Flies! These absurdly fast-flying monsters might be the most dangerous foes they have faced yet—and to make matters worse, the beautiful but hot-headed Rosalie, captain of the Roseguard Imperial Knights, is raring to charge in without a plan. Can Seiya squash these bugs before this underpowered but overly reckless knight gets herself killed?!

After a thief known as the Equipment Hunter suddenly appears in the city of Akiba and attacks people, making off with some weapons and armor, the chase begins for the members of the West Wind Brigade! Soujirou comes along for the ride, along with a mysterious person who looks just like him...!? But there's no time to ask questions-the Knights of the Black Sword have arrived, and an all-out war is about to begin!

After the monstrous Crossed Thanatos follows the party back to the spirit world, Seiya falls back on his standard response to the unexpected—running like hell in the opposite direction. Even a nigh-unbeatable hero might not withstand the implacable pursuit of this logic-defying enemy that effortlessly barrels through gods! But all hope is not lost, as Seiya apparently even knows what to do...when he doesn’t know what to do?!

With stakes this high, is there such a thing as being “overprepared”?! Arriving in the nick of time to save Rista from sudden betrayal, Seiya clashes in a fierce battle with a demonic Emperor Wohlks. Up against the God Eater, a sword capable of destroying the very soul of a being, Seiya quickly finds himself in a fight for his life! What’s worse—no one heard him say, “I’m perfectly prepared…” With the Demon Lord still alive and the fate of Gaeabrande on his shoulders, will Seiya be able to overcome such a fearsome enemy?!

After an unforeseen counterattack from the Equipment Hunter, Soujirou finds himself in a pinch! He is not alone, though, as the revived Kuroe comes to his rescue, backed up by the power of all their friends. As this battle to the death comes to a close, what will Soujirou and the West Wind Brigade lose...and what will they gain?
