Cast-off Magic Tool Researcher is Actually an S-rank Mage

Werner, a brilliant and hardworking magic tool researcher at the Empire’s top institution, the Sage’s Academy, suddenly finds himself expelled by a jealous chancellor looking to profit off of Werner’s inventions. But without Werner, the Academy quickly hits a well, and not a single new magic tool could be developed. It turns out Werner’s theories are way too advanced for anyone else to follow! While the academy flounders, Werner attracts attention from all walks of life—from a maiden dragon to a princess. Armed with the strongest spells and magic tools, he’s ready to enjoy a laid-back life of research...surrounded by cute apprentices to boot! Source: Manga UP!
