Goddess Listarte, the savior of the super hard-mode world Gairbrunde, summons a hero to her aid. The hero, Seiya Ryuuguuin, holds the cheat-rank status, but he is ridiculously cautious. For instance, he would buy three sets of armor: one to wear, a spare, and a spare for the spare. Beyond keeping an absurd amount of item stock, he remains in his room for muscle training till he reaches the max level and fights slimes at full power just to stay on the safe side.
The adventure fantasy novel has been published on the Kakuyomu website since June 2016. Kadokawa began releasing the series under its Kadokawa Books imprint last February with illustrations by Toyota (Densetsu no Yuusha no Densetsu). The fifth volume (pictured) will go on sale on November 10.
Kadokawa's Dragon Age monthly magazine will serialize a manga adaptation by Koyuki (Log Horizon: Nishikaze no Ryodan) beginning this Friday.
