Ep 21 – “Performance” / “Katsuyaku” (活躍)
The third Kira sets his eyes on Misa after meeting her. While Misa is taking a break from meeting with the Yotsuba Group, Rem contacts her. Misa is able to see the shinigami, but her memories of being the second Kira do not return upon touching a portion of the Death Note that Rem has brought her. Rem then tells Misa about everything that has happened and that she must trust Light lest she be killed. Upon re-entering the room, she spots who the third Kira must be: Kyosuke Higuchi. Misa goes on a date with him and is able to obtain proof that Higuchi is the criminal L is looking for. Her ease in determining who Kira is leaves L very suspicious, since he could not deduce it himself.
