Ich habe 300 Jahre lang Schleim getötet und aus Versehen das höchste Level erreicht

A lighthearted fantasy comedy from Altraverse, Ich habe 300 Jahre lang Schleim getötet und aus Versehen das höchste Level erreicht follows an immortal witch who, after spending centuries farming slimes for a peaceful living, accidentally becomes the world's most powerful being. Running since 2020, the series is best known for its gentle humor and the art of Kisetsu Morita, who brings the protagonist's chaotic daily life to charming, low-stakes life. It matters for its clever subversion of RPG power fantasies, turning a simple premise into a warm, ongoing slice-of-life adventure.
