My Lovely Ghost Kana/Nightmare Fuel

When Broken Bird Utako is introduced she is first heard as quiet sobbing coming from the apartment showers. After a frightening (for her) first meeting with Daikichi and Kana, they find she had been living on the streets before moving into the apartments and she becomes their new friend. Then Daikichi gives us this little expository gem, "Apparently while looking for work, she was led to an office and made to sign some contract written in some foreign language she had never seen before. And she hated it because she feared the big men and the cold showers and the dark little room..." Thank you for that gut-punch, Tanaka-san. (Fortunately it is never expanded upon because we really do not. want. to. know. and her life turns around for the better.)
Kana's description of her "life" after her suicide, sinking into the walls and thinking and wondering. And thinking. And thinking, until she lost all sense of who she was and where she was. Then at last she pulled herself together, left the walls, and wandered all around her deserted, rotting apartment, looking to see if anyone had come, until she gave up and went into the wall again. She spent years like that, all alone, trying not to go mad.
