Season 1
I Don’t Know What Moved into My Futon
One day, Yachi Haruaki receives a big black cube from his father, who works overseas. Overnight, the cube morphs into Fear, a tsundere loli who has turned up to remove the curse placed on her through accumulating negative emotions. At night, Haruaki encounters her stealing rice crackers, and allows her to stay at his place, much to the horror of Konoha, Haruaki's childhood friend.
Where, What, Something
Haruaki arranges for Fear to join his school, where to his surprise, she ends up well-liked and happy. After her first day, she goes home with Haruaki and Konoha only to be attacked by a strange woman trying to kill the "Fear in Cube".
The Antimony of Their Temperatures
Using her power to the full to beat Peavey, Fear calls up various torture devices using her cube to attack her, including a massive guillotine that cuts off her left arm completely. Still in a crazed state, Fear attacks Haruaki before running away and trying to commit suicide, but Haruaki goes after her.
At Night, a Mother and a Hugging Pillow
Haruaki and Fear are faced with a life-and-death decision when Mummymaker pays them a visit.
Even If I’m Cursed
The final battle between the maniacal Worse Hunter Peavey Barowoi and Fear happens just as Yachi and Konoha are sidelined! Making matters worse, Kirika is a defenseless hostage... or is she?
Weak, Like a Spherical Glass
After returning to school, Fear and Haruaki are contacted by the principal once again, who tells them that a certain student, Shiraho hasn’t been turning up. Coincidentally, Shiraho was recently sent a box containing a cursed tool, and the doll, Sovereignty escapes by assuming human form. Haruaki and Fear try to track the doll down.
Not Reflected in the Eyes of a Seer
Haruaki, Fear, Konoha and Kirika find some inconsistencies in Shiraho’s story, so they go to check her out in the school records. When they see a picture of Sovereignty instead, they realize that the identities of the two girls aren’t exactly who they assume them to be.
Like an Inescapable Curse
Fear, Konoha and Kirika lure Sovereignty out by threatening to kill Shiraho, and Haruaki is forced to go along with their plan. After managing to call out all parts of the Killing Organ curse, Haruaki dispels the curse and Sovereignty and Shiraho are able to finally embrace. Everyone returns to school and Shiraho becomes a normal student again, with Sovereignty working in the principal’s office in a maid outfit.
