Kono Yo wa Tatakau Kachi ga Aru

Itou Kiri has had enough. She's 25, is in her third year at a company she hates where she's also getting sexually harassed, and dating a shitty guy. She exists solely on energy drinks and one thought: "I want to be useful to others." But she's beginning to reach her limit and feeling hopeless about her future. That is, until she receives a mysterious letter one day.

No return address, no name, just a message she needed: Permission to live freely and on her terms. From that moment, something changes in her and she decides she's doing whatever it takes to live a life worth living. And she's not holding back or pulling any punches.
