Yui again ran into Chinatsu Mihashi, an acquaintance from her karate days. Chinatsu wanted to remind her of a promise they once made to fight at nationals. She also begrudged Yui for giving up karate and becoming a weak person. Aoki continued being unable to clearly know if he loved Yui for her or because she reminds him of Nana Nishino, a former girlfriend of Aoki's. After Aoki sorted out his feelings and reaffirmed her love for Yui, she realized that she needs to become strong again.
Episode 12 of Kokoro Connect was emotionally heavy but kind of disjointed. We finally learned more about Aoki. He had been probably the least fleshed out character up to this point. It is sad that Yui lost some of her conviction to live probably as a result of her attempted rape. This episode had very good moments but nothing overly dramatic. But the last episode of the Kako Random arc promises a whole lot of hell breaking. Episode 12 of Kokoro Connect gets a 9 out of 10.
