I like Touka best when she is at her most flawed.
I love when her abandonment issues show, I love when she’s mean, when she’s rude and abrasive, when she’s violent. These are personality flaws that all stem from the turbulent and traumatic life that she’s led, and they are realistic flaws.
Each and every flaw that Touka is one that makes sense given her past. She had to grow up too young, had to fight tooth and nail to protect both herself and her brother, and had to distrust literally every human that she’s encountered since the faithful night that her father disappeared.
Of course she’s mean. Of course she’s rude, violent, and abrasive. Of course she’s afraid of being alone.
I love Touka’s flaws because they all make it much more poignant when you see that despite those flaws she is capable of great kindness and care. She loves her most important people deeply and will literally risk her safety for them or die for them.
Even at her angriest, she stopped Kaneki from killing his closest friend, she saved Shuu even when he repeatedly attacked her when she was a minor, she made Akira reconcile with Hinami even though her father killed Ryouko, she risked her life to bring Hinami back from cochlea, and she even helped Amon face his fears and talk to the woman that he cares about. I could go on and on about how Touka has helped almost all of the core characters in the series, even when some of them had previously wrong her.
She’s real – and she isn’t sugarcoated. And while some of you want an idealistic female character who is always sweet, and always kind, and always understanding that way of thinking always makes me appreciate characters like Touka that much more.
