Kubo from Miss Kobayashi’s Dragon Maid
This dragonmaid creates food that’s unintentionally poisonous to humans despite her best efforts. Her cooking appears normal but contains toxins that would kill ordinary people. The hilarious contrast between her desire to be helpful and the deadly results of her domestic efforts creates a unique twist on the maid character archetype. Her inability to understand human biology makes each meal preparation a potential disaster, yet she continues trying to improve with endearing determination.
