This short Japanese voice line runs just under three seconds, with Lute delivering the phrase 'Yuushu desu kara' in a bright, self-assured tone that translates roughly as 'I am superior after all.' It feels smug, playful and triumphant, like a confident boast after outplaying someone. The line comes from Lute's Japanese voice set in Fire Emblem Heroes.
