Keikenchi 1 de Level Up Suru Ore wa, Saisoku de Isekai Saikyou ni Narimashita! #3

Keikenchi 1 de Level Up Suru Ore wa, Saisoku de Isekai Saikyou ni Narimashita!—often referred to by the shortened title Level 1 de Level Up—is a light novel series written by Akira with illustrations provided by Nekometaru. The series originated as a web novel published on the user-generated site Shousetsuka ni Narou before being acquired for print publication by Kodansha under their Ranobe Bunko imprint. The third volume, released in the late 2010s, continues the narrative of a protagonist who gains experience points and levels up in an unconventional manner, fitting squarely into the prolific isekai fantasy genre that dominated the Japanese publishing market during this period.

The character design and visual aesthetic for this volume were crafted by Nekometaru, whose style leans into the lighthearted and vibrant tropes common to modern fantasy light novels. The editorial intent for the third installment was to maintain the momentum of the series' core gimmick while expanding the world-building and introducing new companions. Upon release, the volume was received primarily by the established base of light novel readers who enjoy progression-focused fantasy stories, serving as a standard entry in a market where such titles are frequently adapted into manga and anime series.
