Yotaka Futatabi

That woman is "Yotaka." Once famous in the underworld as the strongest assassin, she is now a 33-year-old (and very unlucky) drug addict and alcoholic. She's enjoying her unemployed life in a rundown apartment. ♪ With her mind and body completely slack, Yotaka receives an invitation from her assassin friend, "Kohai," to return to active duty...!!

Will she return to the battlefield once again?! Yotaka!!!
