Taeko

Taeko is an assassin that appeared in the prequel Akame Ga Kill!: Zero. She is one of Chelsea's previous teammates.

History
Taeko was found and raised by the Oreburgs as an assassin. She was eventually assigned to work with Babara Oreburg and Chelsea.

She was then hired by the Revolutionary Army along with Babara to dispose off the Elite Seven which has been posing a threat to the Revolutionary Army by eliminating it's supporters. While staying at a hot spring inn to plan their next move after the failure of their first mission that ended with the annihilation of the Tengu Mercenary, she meets and befriends Cornelia, unaware of her Identity. Eventually learning about her Identity from Chelsea, she calls Cornelia out and engages against her in a death match and kills her after destroying the latter's Shingu.

Equipment and skills
Having been trained from a young age, Taeko is an extremely powerful combatant. She was also to fight on par with Cornelia. She also possessed an immense endurance, taking a direct hit from the former's Pulverization King with minimal injuries and continuing to corner Cornelia.

Taeko also carried a sword that contains a poison concocted by the Oreburg that can't be cured.
