When a support mage is kicked out of his group for outshining the hero, he becomes a member of an elite guild where he can really show off his powers! The light novel that inspired the manga–also available from Seven Seas.
Wim Strauss isn’t a flashy fighter—he’s a granting caster, a support mage who boosts his allies’ strength in battle. His magic keeps the party alive. But when his quiet power starts to overshadow the wrong person, the team’s prideful leader has him unceremoniously kicked out.

Enter his slightly clingy childhood friend Heidemarie, now a member of Nachtlibelle, a renowned A-rank guild counted among the strongest in the land. She offers Wim a chance to join her team—a fresh start among allies who actually value his skills. His magic may not dazzle, but with the right party behind him, he just might prove that the back line was never where he truly belonged.
