実は俺、最強でした? [Jitsu wa Ore, Saikyō deshita?] #1

A lively opening volume of this isekai manga that sets its tone right on the cover: a blue-eyed young man in a white jacket juggles a glowing geometric crystal while a fox-eared girl with vivid red hair and a playful grin leans in beside him, the two framed against a charming European-style townscape. The title — roughly "Was I Actually the Strongest All Along?" — telegraphs exactly the kind of underestimated-hero fun this series promises. Published by Kōdansha under the Sirius KC imprint, it's a bright, energetic start to what looks like an adventurous and warmly comedic fantasy.
