What Dwells In Your Heart? (胸の中にいるのは?; Mune no Naka ni Iru no wa?) is the second episode of the Akuma no Riddle anime series and was released on April 10, 2014.
The next school day, as more students join the 10th year's Black Class, Haru decides to have lunch with Tokaku, whilst the other students hear from Nio Hashiri about a meeting concerning their mission.
Later that day, classmate Isuke Inukai comes around to have tea with Haru, slipping her a sleeping drug with the intent of drowning her in a bath whilst she is asleep. When Tokaku learns from Haruki Sagae that Isuke is targeting Haru, she rushes back to her room to stop Isuke, fighting against her to protect Haru. Isuke overwhelms her after Haru becomes hesitant to kill her, but decides to take her leave. After Tokaku regains consciousness, Haru, who was actually aware of what was happening and knows she is being targeted, asks her why she came to her rescue, stating her determination to graduate from Black Class alive to honor her family who died protecting her.
That night, a meeting is held amongst the other assassins where they are briefed on their mission. Each assassin is given one opportunity to assassinate Haru, and whoever kills Haru first will have any wish they desire granted, with those who fail their assassinations becoming expelled. Upon arriving at the meeting, Tokaku announces that she has defected to Haru's side and will be her protector.
